		<H1>Phylum Mollusca</H1> ^Votes:0 PHYLUM MOLLUSCA Class Polyplacophora (The Chitons or Coat-of Mail Shells) The chitons have long been my main academic interest. When I moved to Scotland, I discovered a large population of the british intertidal species, Lepidochitona cinereus . Although common, it rarely occurs in densities which make ecological and population studies practical but at Easthaven, near Dundee, it occurs in unusually high densities. Thus my early publications were on the ecology of this species. However, the shell valve structures called aesthetes then caught my attention and a period of examination of aesthetes in different species followed. My interests have now widened, particularly with exposure to the Australasian species and my interest now lies in comparative anatomy and morphology of these almost uns Read More Go to Site

At the 1994 Abalone Symposium it was decided that communication between abalone researchers could be facilitated by setting up a listserver for posting of messages. This was done by Neville Sweijd of UCT. In 1995 it was decided to takes this one step further by distributing information via a worldwide web server. These pages are the result and the role of ABNET has now expanded somewhat. The ABNET listserver is still operating as it has before and you can subscribe and post to ABNET via these pages. The ABNET Archives will be viewable here for members and will be regularly updated.

They are the simplest of all theanimals, and have only three basic types of cells: epithelial cells,that protect the sponge; collar cells, that process food; andamoebacytes, that carry food from the collar cells to the epithelialcells. They have a central gastrovascular cavity, through which waterand food flow. Sponges are considered to be animals and not protistsbecause they are made up of several differentiated kinds ofcells.

		Crustacea - Introduction ^Votes:0 Unit: Crustacea 1 Introduction CRUSTACEA There are about 42,000 species of Crustacea, including many of the most familiar arthropods such as the crabs, the lobsters and the woodlice. Crustacea is the only group of arthropods that is primarily marine, though there are many fresh water species also. There are some semi-terrestrial species, but these are not, in general, well adapted for life on land. In contrast with other members of the phylum Arthropoda, most notably insects, crustaceans have not been very successful on land. This can be attributed to a number of CONSTRAINTS. However, Crustacea have exploited every habitat of the marine environment, and in so doing have become a very diverse group, from the very large Japanese Spider Crab (look at the specimen in the museum), to the tiny p Read More Go to Site

It?s called an exoskeleton , and it can?t stretch as the animal grows bigger. Crustaceans have to shed their armor now and then and grow a new set. This is called molting .?

		Echinoderm larvae are bilaterally symmetrical-even though the adults rarely are ^Votes:0 Echinoderm larvae are bilaterally symmetrical-even though the adults rarely are. This suggests strongly a bilateral ancestor. The larvae of each class have distinctive names associated with them. Echinoderms have well-developed powers of regeneration. Some voluntarily break themselves into pieces and regenerate into complete clones. This process can occur at various stages of development. In some species, the larval forms divide and give rise to new individuals. Before going through each class of echinoderm, I?d like to mention why they are an important group. Arthropods and Molluscs warrant studying by their extreme diversity and species number alone. Since echinoderms are a smaller group-I?d like to provide some justification for their study- Some are of great economic and ecological imp Read More Go to Site

		Echinoderm showcase ^Votes:0 Echinoderms are known from the Cambrian until today. The extant echinoderms comprise sea lilies, sea cucumbers, sea stars (starfish), brittle stars and sea urchins. They are all marine animals. The skeleton of an echinoderm consists of calcite plates covered by a thin skin. The calcite plates are therefore an inner skeleton. The animals breathe by assimilating oxygene from the sea water being pumped through a vascular canal system. Food is brought to the mouth through the movement of tube-feet along special food-furrows. The tube-feet are external extensions of the water vascular system. In addition, the starfish, brittle stars and sea urchins use the tube-feet for locomotion. Most echinoderm adults have a five-rayed symmetry. They do not posess a head, and in most free-living species, the Read More Go to Site

		Echinoderms ^Votes:0 Invertebrates in the Plankton: Echinodermata The echinoderms include the familiar sea stars, brittle stars, and sea urchins, as well as the more enigmatic sea cucumbers and crinoids. All species are marine, and most live in benthic habitats. Many of the animals have a planktonic larval stage, some of which may live in the plankton for months before settling as adults. Echinoid larvae are among the smaller meroplankton , approximately 0.01-0.03 mm in length, and are relatively rare to find in the plankton. Consequently, we borrowed some specimens from other researchers at FHL for these photographs. Asteroids Sea stars, or asteroids, develop through several larval stages, including this brachiolaria larva of the ochre seastar, Pisaster ochraceous .

A nimals are multicellular organisms with no cell walls and no chlorophyll. They usually ingest other organisms for their energy and other nutrient needs. Animals are divided into several groups [phyla]. The lower groups (sponges through echinoderms) are often classified together as the invertebrates. The Sponges. These simplest animals do not have any distinct tissues (a tissue is a group of cells with similar structure and function). They live in water, most being marine. These include a variety of sponges other than the common commercial sponge. The Cnidarians (Coelenterates). These animals have simple tissues and radial symmetry.

		Fossil Groups - Mollusks ^Votes:0 Mollusks What are Mollusks? Mollusks are an amazingly diverse group of animals that live in a wide variety of environments. They can be found inhabiting trees (Figure 1: D ), gardens, freshwater ponds and streams, estuaries, tidal pools, beaches, the continental shelf, and the deep ocean. Some mollusks are excellent swimmers, others crawl or burrow in mud and sand. Others remain stationary by attaching themselves to rocks, other shells, or plants; or by boring into hard surfaces, such as wood or rocks. Adult mollusks can range in size from a few mm (0.1 in.) to over 22 m (>70 ft.) in length as documented for some giant deep-sea squids. Their weight can vary from a few mg (a fraction of an ounce) to over 227 kg (500 lb.) as recorded for the giant south Pacific Tridacna clams. The number Read More Go to Site

Famous for its rich fauna, with many small animals swimming in the water, attached to substrates or living on the bottom. With some patience it is possible to find the larvae of animals like the common starfish ( Asterias rubens ) in the plankton and to follow the development of these larvae into miniature sea-stars. Larvae of other echinoderms are also present in the plankton, like those of sea urchins, sea cucumbers and brittle stars. Larvae of sea cucumbers and starfishes don't have a skeleton, those of sea urchins and brittle stars possess an internal skeleton, consisting of skeletal sp Read More Go to Site

The biomass of Gump's oceans is one and a half times that of Earth. There are many reasons for Gump's abundance of sea life. First, Gump is a planet that is mostly tropical. As mentioned earlier, this is due to the 10 degree tilt of its axis. Much of the JAM's solar energy, along with the heavy carbon dioxide in the air, help to make Gump a warm planet, especially at the equator where it is hot and steamy.

		Introduction to the Echinodermata ^Votes:0 Introduction to the Echinodermata . . . from starfish to sea cucumbers. . . A nyone who has been to the beach has probably seen starfish or sand dollars. The more intrepid beachcomber may find brittle stars , sea cucumbers , or sea urchins. These and many other organisms, living and extinct, make up the Echinodermata, the largest phylum to lack any freshwater or land representatives. Most living echinoderms, like this sand dollar from Baja California, are pentameral ; that is, they have fivefold symmetry, with rays or arms in fives or multiples of five. However, a number of fossil echinoderms were not pentameral at all, and some had downright bizarre shapes. Echinoderms have a system of internal water-filled canals, which in many echinoderms form suckered "tube feet", with which the animal Read More Go to Site

		MARINE CRUSTACEANS OF SOUTHERN AUSTRALIA ^Votes:0 Crustaceans come in many sizes and forms and are some of the most common creatures that you will find on the shore, in your fishing net and in the seafood section of your local market. This guide has been put together by Museum Victoria, Melbourne, as a reference for the identification of a few (about 100) of the thousands of species of marine crustaceans known to exist in southern Australia. Crustaceans are, like insects, arthropods. That is, they have a tough external skeleton and jointed legs. Most live in marine environments but a few are found in rivers, streams or on land. You are probably familiar with many of the groups of crustaceans described in this guide. Some however are less well known and thanks to the spectacular photographs, their beauty can be shared with you. CONTINUE St Read More Go to Site

		Mollusks ^Votes:0 Discovering Life on a Living Planet Mollusks The second largest phylum after arthropoda, Mollusca includes more than 70,000 species, including snails, clams, squids, and octopuses. Their primary characteristic is the hard shell to protect their soft bodies. Even squids and octopi retain evolutionary fragments of internal shells, as they usually lack external ones. The Smithsonian's Mollusk Collection contains more than 15 million specimens. Biologists study them to discover how these animals live and adapt. One of the most beautiful--and deadly--mollusk families represented here is the Conidae, a group of marine snails with cone-shaped shells. They possess a harpoon-shaped hollow tooth containing a potent neurotoxin that paralyzes their prey and can kill humans. Cuban Land Snails Imperial Read More Go to Site

		Mollusks ^Votes:0 Mollusks The Phylum Mollusca is second in size only to the Phylum Arthropoda. Although members of this phylum are extremely diverse in structure, physiology, and habits, they are built on a uniform body plan consisting of a mantle , shell , and foot . The mantle secretes the shell and is sometimes involved in respiration. The shell provides support, protection, and secure attachments for muscles. The foot is fleshy and contains most of the viscera. Figure1. Representative of the Phylum Mollusca.

Most Mollusca are soft fleshy slug like creatures that have an hard external skeleton type structure to help protect them. Mollusca can be found in both salt and fresh water, as well as on the land (snails). In the oceans, this structure is known as a seashell. There are over 60,000 known species of Mollusca. Mollusks are adapted to live practically anywhere. From the most barren sand bottom to the most elaborate coral reef. Shells have been in existence for millions of years and have been recorded in history in almost every journal. Sanibel Island is one of the best places to gather seashells on the beach in the world.

		MONSTER MOLLUSK FOSSIL FOUND ^Votes:0 -Advertisement- MONSTER MOLLUSK FOSSIL FOUND By Sean Henahan, Access Excellence WEST LAFAYETTE, Ind. - Sixty-five million years ago, a giant 12-foot long mollusk lived at the bottom of the sea near Antarctica. The discovery of a complete fossil of the creature, an ammonite known as Diplomoceras maximum, is causing researchers to rethink their ideas on mollusk evolution. Ammonites, which are related to the pearly nautilus, are among a group of invertebrates that date back more than 400 million years. The animals vanished approximately 65 million years ago, the same time that dinosaurs became extinct. The Diplomoceras takes it name from its tube-like shell that doubled back upon itself. The pleated shell resembled a clothes dryer vent hose curled in the shape of a paper clip. The fossil shel Read More Go to Site

		Science News Online (3/13/99): Octopus suckers glow in the deep, dark sea ^Votes:0 The Weekly Newsmagazine of Science Volume 155, Number 11 (March 13, 1999) Octopus suckers glow in the deep, dark sea By S. Milius A red octopus that drifts through deep waters off the eastern United States shines in a novel way: Its suckers flash on and off. Finding luminescence in any of the known octopus species surprised codiscoverer Edith A. Widder of Harbor Branch Oceanographic Institution in Fort Pierce, Fla. The seas where octopods live sparkle with constellations of bioluminescent fish, squid, crustaceans, and other creatures. Yet the only octopods previously found to luminesce belong to two or three species in which females develop bright rings around their mouths just before mating. The light organs that Widder and her colleagues describe in Stauroteuthis syrtensis lie in a singl Read More Go to Site

		Science News Online - Past Issues - News Feature - 9/14/96 ^Votes:0 September 14, 1996 An illuminating partnership for squid By John Travis The squid Euprymna scolopes , a denizen of the shallow waters surrounding the Hawaiian archipelago, provides a shining example--literally--of symbiosis in action. The cephalopod's symbiotic partners are the bioluminescent bacteria Vibrio fischeri . These bacteria colonize a specialized cavity called the light organ, located on the squid's underside, and allow the animal to emit a diffuse glow toward the seafloor. The result appears to be counterillumination, which eliminates telltale shadows, thus enabling a variety of fishes and cephalopods to move and hunt undetected at night. With the aid of its microbial tenants, E. scolopes may "camouflage itself against the moonlight and starlight," explains Margaret Mc Read More Go to Site

		Sea and Sky: Echinoderms Page 1 ^Votes:0 Enter your search terms Submit search form Web www.seasky.org Echinoderms Page 1 The echinoderms are a group of animals that includes starfish, urchins, feather stars, and sea cucumbers. They are simple animals, lacking a brain and complex sensing organs. Echinoderms are characterized by their radial symmetry and a central mouth. Although a sea urchin looks round, closer inspection reveals that it is nothing more than a starfish with its legs wrapped inwards to form a sphere. The echinoderms are found in a stunning variety of shapes and colors, and are found decorating reefs around the world. Some of these animals are carnivorous, feeding on corals and scavenging the ocean floor. Certain species of starfish actually extend their stomachs into their unwary victims in order to digest them.

		Some Weird Echinoderms of the Cincinnatian ^Votes:0 Some WEIRD ECHINODERMS of the CINCINNATIAN Compiled by Colin D. Sumrall Introduction Echinoderms are one of the most diverse groups of marine animals that today includes starfish and sea urchins. Most members of the phylum have five-part symmetry, although there is some variation. Echinoderms had a flowering of diversity in the Early Ordovician, and worldwide there are more than 21 classes known. In the local Cincinnatian, however, there is a surprisingly low diversity with only seven classes present, including crinoids, edrioasteroids, starfish, brittle stars, Glyptocystitid Rhombiferans, stylophorans, and cyclocystoids. Crinoids and edrioasteroids are familiar to most local fossil collectors and are relatively common fossils in this area. Although rare, starfish and brittle stars are com Read More Go to Site

(Okay, I don't often get asked this one, I admit it.) Or: "Tell me in highly technical terms how starfish find their food." Where do starfish fit in, taxonomically? (Kingdom, phylum, and other things you need for your homework.) Why do starfish always have five rays? Can starfish regenerate rays? What do starfish eat? What eats them? How do starfish move around? How do starfish digest their food? What about their circulatory system? And how do they breathe? How do starfish reproduce? How do starfish think?

		The Lurker's Guide to Stomatopods - Mantis Shrimp ^Votes:0 Sponsored Link //--> //--> Let's go Devils! Why Bush is Bad for US © Takata //--> Stomatopods (mantis shrimps) are predatory crustaceans that live in the shallow waters of tropical and subtropical seas. They use specialized raptorial appendages to capture and subdue prey by either "spearing" the animals or "smashing" them with heavily calcified clubs. The force of the strike of a large Californian species approaches that of a 22 caliber bullet, and is capable of breaking double layered safety glass. They are, weight for weight, probably the most formidable animals alive. I have been interested in mantis shrimps since I first read about them in early 1998 , and I hope this site will give you a very good idea why mantis shrimps are one of the most remarkable and fascinating animals on earth.

		The UnMuseum - The Giant Squid ^Votes:0 The Giant Squid The giant squid is a deep-sea dweller that can grow to the size of a bus. (Copyright Lee Krystek, 2003) The French dispatch steamer Alecton was cruising off the Canary Islands late in November of 1861 when its crew spotted something unusual in the water. It looked like a large sea monster with many arms and a long tail. The gunboat, firing cannon and musket at the strange apparition, pursed it until they could get close enough to throw harpoons into it's body. The harpoons wouldn't stay in the flesh for long, but finally the crew managed to get a noose around the tail of the monster. As they tried to pull the thing aboard, the rope tightened and cut though the animal. Most of the creature sank into the sea, but the ship's captain, decided to take the tail of the thing back Read More Go to Site
