Crustaceans

The Antennules in a Crayfish, being short while the Antennas are long, are used to taste food.

No fishes dont feel pain or threat because they have very primitive responses and sensory developemnt.

The heart of the crayfish pumps to circulate the blood. The blood flows through the open cavities as there is a minimum of tubing in the crayfish. The circulation of the blood aerates and purifies it.

A herd

You can eat mole crabs if you wish, though in the United States these small crabs, also known as sand crabs, are more often used as bait. One way to eat them is to rinse the sand from them and boil them up into a broth.

No, for the most part, sea stars are meat eating predators, many choosing to feed at night. They are able to sneak up on sleeping fish, covering their homes in the reefs, and devouring them on the spot. Sea stars can extrude their stomachs and digest their meals.

Crown of Thorns sea stars are known for eating corals, but will scavenge on dead fish when found.

They got their name because they are similar to a crab.

The hermit crabs first pair of legs are their claws which they use for drinking, eating, and defense. The second, third, and fourth pair are for walking. The fith - tenth are for holding it's abomen inside it's shell.

A crayfish has eight walking legs and eight swimmerets.

No, crayfish are invertebrate animals, they do, however have an exoskeleton which makes up for the lack of a backbone.

Crayfish can sense changes in water pressure. They can also see to a limited extent. Additionally, they have two sets (pairs) of antennae that are sense organs. A link can be found below.

there are many types of prawns.

- tiger prawns

-lobster

-shrimp

-king prawns

-North Atlantic prawns

-baby prawns

i hope this i enough

what is a grade prawns

If you like seafood such as lobster or shrimp, you will likely enjoy crayfish (also called crawfish or crawdad in the US). There are many ways to cook them in dishes or boil them in a flavorful broth and eat them out of their shells.

I have a crayfish and its been alive for 4 years now. We feed it usually cheap goldfish, about a dozen 3xs a year or so. They also like earthworms, raw meat and anything else thats alive or lived at one time. They are bottom feeders so they will eat scraps

First, when it needs to get away, it tucks in the abdomen so it can swim away backwards, really really fast... Also, the abdomen can stir up the dirt so the predator can't see.

you take a cup of pee and pour it on the bug and the bug wil be gone in a giffy.(5SECONDS) you squash them under your shoe. if you are a woman wearing a high heel shoe you need to grind or smear him so he is squashed completely

Yes. I have a five gallon tank with two goldfish and a blue crayfish and they have lived happily for several months. Granted, the crayfish may snap at the goldfish, but if you choose fast goldfish they should be fine.

no, they have other mouth appendages though such as the 1st and 2nd maxillias, right behined the mandiable(jaw). Then the 1st, 2nd, & 3rd maxillpeds come after that. The maxillias and the maxillpeds hold the food in place and they sense taste and touch.

Because they are delicious!!

No seriously here is what I found:

"Crayfish are threatened by habitat destruction caused by dams, water pollution, erosion, siltation, in-stream gravel dredging and, particularly, the introduction of nonnative crayfishes and other exotics. About 65 species of crayfish are endangered, threatened, or listed as species of special concern by the states in which they live, and 48 percent of our native crayfish species are in need of protection. These numbers are best estimates only. The exact status of crayfish endangerment or extinction rates in the United States is largely unknown because very few distribution and population surveys have been completed. "

Here is a link to the site where I found this information:

They can have up to 15 babies at a time and can carry 30 in there tummy.


They are red poisonous spiders if you see one in your house kill it straight away.

I would feed it about once every two days in a little lid or something where it can get food and water as it needs.

It depends on the clam species. Apparently, some start out as little swimming larvae, and secrete a hard shell during one of their larval stages, or when they go through metamorphosis. Other species are released from the parent's mantle cavity as fully developed little clams.

A potato bug is a awful looking bug that looks like a half bee half spider and half cricket.

Type in Potato Bug on google.com the you will see how grose it looks like.

Crayfish look like small version of New England type of Lobsters. They live in fresh and brackish waters depending on the species. They will eat anything that is meaty, including worms, leaches, larvae or their specialty, sleeping fish.

Crayfish (or crawdads) live in aquariums.They can go extremely long periods of time without eating and they will eat gunk that is stuck to the bottom of the aquarium and live fish. Sometimes they will also eat fish food and shrimp pellets. if there are other fish living in the aquarium, make sure you cut of the crayfish's claws so they cannot catch the fish(it does not hurt them and the claws will grow back when they malt their exoskeleton). temperature and lighting do not really effect the crayfish so you don't have to worry about controling that. Every 3 to 12 months, a crayfish will malt its exoskeleton; leave the old exoskeleton in the aquarium for the crayfish to eat because this will help him grow a healthy one the next time. Crayfish like to have a rock or cave-like structure to shelter in.
