which organism eats crustaceans?

wow...  it might be easier to list the animals that don't. When you add in fresh-water crustaceans, you get even more mamals and such. In fact, between zooplankton and shrimp alone, probably 90% of the aquatic population eat crustaceans, from simple hydra all the way up to baleen whales.

insecto (some people eat insects)

There are many species of crustaceans, which are you referring to (i.e shrimp, crab, lobster, etc)?  Most have considerable cholesterol and modest levels of protein.

What you're looking for is Krill, they're tiny arthropods in the same family as shrimp.

Usually they are scavenging feeders but to be specific they eat certain types of fish, crusteans and mollusks such as octopuses, squids and crabs\n\nhttp://www.sea-ex.com/fishphotos/flathead.htm

That sounds like the mantis shrimp.  It's not a crab, but it isn't really a shrimp either.  Shrimp and lobsters belong to the order decapoda.  Mantis shrimp belong to the order stromopoda.\n\nThey have two club-like apendages in front of their legs.  The power of the appendage can produce a blow close to the power of a .22 caliber bullet.  They use this club for self defense, fighting rival mantis shrimp and cracking open hard shells of its prey such as crabs and mollusks.

They vary as widely as the body plans of different mollusks, but basically there are both macrophagous (herbivores and predators) and microphagous (suspension feeders) forms.\n \n**Gasteropods (snails and slugs) are mainly herbivorous; they use their radula to scratch plant tissues. However, there are also predatory snails (with modified radula, or proboscis, or even a venom-injecting radula). There are also microphagous planktonic forms (pteropods).\n**Cephalopods (squids, octopi and their relatives) are predatory carnivores, they have a modified radula and a horny "beak" with which they eat different invertebrates and vertebrates.\n**Bivalves (clams, mussels, oysters, etc) are primarily microphagous or suspension (filter) feeders. They don't have a radula and rely on their modified gills for filtration. There are also some primitive detritivores among the bivalvians.\n**The chitons (Polyplacophora) are grazing herbivores (with  radula).\n**The Scaphopoda (tusk shells) capture small food items (particulate matter) with their tentacles (captacula).\n**Other less known mollusks include the caudofoveatans (these capture foraminiferans and other very small organisms from sediments), solenogasters (these eat corals) and monoplacophorans (with a radula, but not much is known about their ecology).

usually, they eat each other. Have you ever heard that "the big fish eats the small one"? Also, they can eat plancton, or algae... there are plenty of food (organic material) floating around in the ocean.

Most arthropods: insects, lobsters, shrimp, crabs, etc. all have a tubular heart on the dorsal area just under the thorax, cephalothorax. Your vertebrates begin the two chamber linage.

Most Water Bugs feed on aquatic crustaceans, fish and tadpoles.

the large ones eat meat..like pieces of raw chicken and beef...the smaller ones just eat bugs the fly by and land on it

Rotifers   are the only I can think of  now if it were Phylum Mollusca it could be Snails, Clams, and squids\n                                 good luck

There are many species of insect eating plants throughout the world. The Venus Flytrap is only one of many. There are sundews which use sticky tentacles to trap prey, Pitcher plants which use a pit fall method to drown prey in a pool of digestive juices, Butterworts are like flypaper, and bladderworts have a unique suction trap that sucks microscopic animals into them. There are many sites covering these plants on the internet, and most people are surprised how easy these plants are to grow. You'll find the link to my site below.
