U.S. Department of the Interior U.S. Geological Survey Arctic Ostracode Database Metadata: Citation: Originator: Thomas M. Cronin Originator: Thomas R. Holtz Originator: Elisabeth M. Brouwers Originator: William M. Briggs Originator: Robin C. Whatley Originator: Adrian Wood Title: Arctic Ostracode Database Reston, VA Publisher: U.S. Geological Survey Description: Abstract: The Arctic Ostracode Database provides species census data for about 100 species of benthic marine Ostracoda from modern surface and late Quaternary sediments from various parts of the Arctic Ocean and adjacent seas. Ostracodes are a microfossil group of bivalved Crustacea that secrete a calcareous shell commonly preserved in sediments in the Arctic region. Because many ostracode species have ecological limits controlled by temperature, salinity, oxygen, food and other factors, they can provide an important tool for paleoceanographic reconstruction in the Arctic. Some recent applications of ostracodes to understanding Arctic Ocean history include Briggs (1983), Reimnitz et al. (1983, 1992), McDougall et al. (1986), Clark et al.(1990), Pak et al. (1992), Brouwers et al. (1991), Cronin et al. (1993, 1994, 1995), Penney (1993a,b), Nurnberg et al. (1994), and Briggs and Mudie (in prep.). Purpose: Ostracodes are a microfossil group of bivalved Crustacea that secrete a calcareous shell commonly preserved in sediments in the Arctic region. Because many ostracode species have ecological limits controlled by temperature, salinity, oxygen, food and other factors, they can provide an important tool for paleoceanographic reconstruction in the Arctic.

23. Game, Poultry, Crustacea And Fine Foods From Land, Sea And Air Suppliers of game, poultry, crustacea and fine foods. http://www.landseaair.co.uk/

Welcome! A warm welcome to the web site of Land, Sea and Air. We are wholesale suppliers of game, poultry, shellfish and crustacea. We have been exporting game and shellfish from England to wholesalers in Belgium, France and the Netherlands, but are now expanding sales within the UK via the Internet. All game is supplied fresh and oven ready in season, with shellfish and crustacea being dispatched within hours of being landed, so that you receive wonderful fresh produce direct to your door. We are linked with a grower of the world famous Native Colchester Oyster. There have been flat oysters (ostrea edulius) grown within the boundaries of Colchester since the Romans settled there in 50AD, and the genuine Native Colchester Oyster can only be grown and harvested by a handful of companies operating within these boundaries. The Colchester oyster is a gourmet product to be found on the menus of some of the world's most exclusive restaurants. Home Page Colchester Oysters Contact Details var site="sm5landseaair"

Web Services Crustacea Research conducted in our laboratory focuses on biodiversity and phylogenetic relationships within and among the various crustacean lineages. Crustaceans are members of the phylum Arthropoda. They are primarily marine, but many also inhabit freshwater and terrestrial habitats from the deep-sea to the highest mountain lakes. More than 52,000 species of crabs, shrimps, lobsters and their close relatives have been described; that figure is twice the number of all amphibians, reptiles, birds, and mammals combined! Although the insects still rule in terms of numbers, the crustaceans are the most diverse in terms of form. The largest of the crustaceans include the the giant Japanese spider crab ( Macrocheira kaempferi ) with its four-meter legspan, the Alaskan king crab ( Paralithodes camtschatica), which can weigh more than 10 kilograms, and the giant Tasmanian crab ( Pseudocarcinus gigas), which has been recorded at an impressive 14 kilograms. On the other end of the spectrum, some crustaceans never grow larger than 0.25 millimeters, even as adults. Crabs, shrimps, and lobsters are well-known crustaceans. However, barnacles, pillbugs, amphipods, copepods, krill, crayfishes, sea fleas, clam shrimps, fairy shrimps, and many others also belong to the Crustacea, an ancient group that arose in the early Cambrian nearly 600 million years ago.

Deformed claw of the European Lobster This appendage with a extra claw was found on a lobster caught by John Barker (Shoreham) Hermit Crabs information file for children Hermit Crabs for the younger student (NE Atlantic species only) Intertidal Crabs: British Coast Why Do Crabs Walk Sideways? Because that's the way their legs bend. Muscles work in pairs. A muscle can only retract, or pull; to lengthen again it must relax and be pulled back by another 'antagonistic' muscle. The muscle blocks in crabs are attached to the inner surface of the exoskeleton, including the ten tubular legs, including the legs with claws, or chelae , as well as other appendages. Crabs do not have ball-and-socket joints but the legs pivot at numerous peg-in-socket joints that are sealed by flexible chitin, and can move in one plane (similar to our knee). Each joint moves in a different plane, and so together they allow the crab to move in all directions like our shoulder and hip joints. However, many crabs have joints in their legs moving in a restricted number of planes so that they can only move sideways. The sharp ends of each leg grip on to surfaces and can grip on to tiny irregularities (watch a Hermit Crab climbing up an almost smooth rock). In some crabs, the rear legs are shaped like paddles for limited swimming.

Palaemon serratus Crangon crangon Palaemon elegans Palaemon serratus PRAWNS AND SHRIMPS A long-handled prawn or pond net dipped into a rock pool at mid-tide level or below, or edged around the weedy surrounds of a pool, is likely to catch a jumping mass of prawns of different sizes. Crabs will grapple with both the inside and the outside of the net, and on many of the British shores small fish like young wrasse will almost certainly be caught, but they are likely to be far outnumbered by prawns. Is it a Prawn or a Shrimp? Alas, there is no absolutely correct answer. In common usage the names are interchangeable, and there are lots of prawn-like or shrimp-like animals to confuse the novice rockpooler. Marine biologists will use the scientific names. However, the casual rockpooler wanting to put a name to what he finds can follow the terms used for British species only:
