and ctenophora. ... Examples of animals that possess bilateral symmetry are: flatworms, common worms ("ribbon worms"), clams, snails, octopuses, crustaceans, insects, spiders, brachiopods, sea stars, sea urchins, and vertebrates.
Only now can we start to unravel the influ-ence of se a ice on the weather that is experienced in southern Australia. But in another way the extent of se a ice extends its influence far beyond Antarctica. Antarctic krill-the small shrimp-like crustaceans that are the staple diet for ...
In crustaceans, production of molting hormones (or ecdysteroids) by the molting glands (Y-organs; YO), is under negative control exerted by a neuropeptide, the molt-inhibiting hormone (MIH). MIH of the crab Carcinus maenas inhibits in vitro steroidogenesis of basal (intermolt crab) or ...
Why are small swimming crustaceans not nearly as streamlined as larger fish? Which animal species would be the best and worst ft to adhere to a ketogenic diet? Explain based on anatomy, digestion, absorption and metabolism of animal species....

This is a characteristic feature of certain animal phyla. 2. Evaluating the Options: - (a) Arthropoda: This phylum includes insects, arachnids, and crustaceans. They have an exoskeleton and do not exhibit a true coelomate body plan. - (b) Oligochaeta/Earthworm: Earthworms belong to this class...
There is also evidence to suggest that grazers (animals that feed on plants or stationary animals), particularly selective grazers, can influence the phytoplankton species composition.Many copepods (small, herbivorous crustaceans) and invertebrate larvae pick out selected phytoplankton species from mixed gr...
3. Examples of Molting Animals: - Various arthropods undergo this process, including insects (like cockroaches), crustaceans (like crabs), and arachnids (like spiders). 4. Identifying the Animal: - The question asks for an example of an animal that periodically casts off its exoskeleton. A...
