Crustaceans
Usually considered as a subphylum, Crustaceans comprise a group of arthropods including crabs, crayfish, lobsters and shrimp. Most crustaceans are aquatic animals, though some are terrestrial, parasitic and barnacles. Crustaceans have a chitinous exoskeleton, segmented body, and paired jointed limbs.

Why is the krill so important to the survival of every other animal that makes Antarctica its home?
Antarctic krill -- Euphausia superba -- form the base of the food chain in the Southern Ocean that surrounds the Antarctic continent. It is the most productive protein source on earth.
No animal 'makes its home' on the Antarctic continent.
Krill provide a bait source to catch fish. Fish is a food source common taken in Antarctica due to lack of other food sources and the soil has no ability to farm with. Also Krill are important food sources to seals and penguins.
I suppose you could call the crayfish the cousin of the lobster. Crayfish certainly look like lobsters. But they are fresh water animals and lobsters are salt water creatures.
Crustaceans are organisms under the subphylum crustacea, encompassing over 50,000 species. Their eating habits are not all the same, so you can not make a general statement.
Mantis shrimp are carnivorous hunters, copepods are often herbivorous, caridina shrimp are often omnivorous scavangers... It would be better to refine the question further.
I wish I could give you a reliable general statement, but I don't know the 50,000 species, haha. Sorry!
yes krill is eaten by pretty much any fish in the ocean were krill can be found. When most people think of krill they think of a whale, being that the krill is the whales main source of food.
How do crustaceans respond to their environment?
Crustaceans use their antennae to discern changes in their environment. They can sense changes in water pressure with their antennae. They use these because their hard outer shell does not have any sensitive nerve endings.

Where do lobsters live in the ocean zones?
Adult lobsters live from the shoreline to beyond the continental shelf. Lobster eggs and larvae have a planktonic phase usually near the surface, for up to about 10 weeks, are subject to irregularities of ocean currents and can get carried beyond this zones. Lobsters also evidence the phenomenon of long distance migration which they accomplish in single-file formation; in these cases they still remain fairly close to the shore. In winter times the females may prefer deeper waters for warmth because of reproductive considerations.
Why are mandibles removed last on a crayfish?
mandables are removed last because attached to them are the maxillae and aixilliped, so those would be removed before, leaving the mandibles last.

What kind of tails do lobsters have?
The tail of the lobster is often intended to indicate the muscular, chitin-plated articulated segmented abdomen (which ends up with butter and lemon on your dinner plate); which has six segments and bears pleopods (swimmerets). At the terminus of the abdomen are the uropods (on the outside), which together with a telson (center) form the lobster's tail fan, which among other functions assists in locomotion in an escape behavior shared by other decapods called the caridoid escape reaction.
What are some water invertebrates?
Some invertebrates that live in the water are:
* Shrimp * Lobster * Clams * Jellyfish * Starfish * Crabs * Mollusks * Snails
