Crustaceans

Insects must have a head, thorax, and abdomen. They have three pairs of legs and usually two pairs of wings. The crayfish obviously doesn't have wings, (not sure about the other requirements) so it is not an insect.

the colours of a cray fish are usully red , orange and brown

Crayfish, lobsters, and crabs are all examples of crustaceans.

Tie up the lobster's claws and then hold its body with two hands. After that, crack it in half. The most humane way is to put the live Lobster into the deep freeze for about an hour before you want to cook it, this shuts down the Lobsters systems, it goes into a deep sleep, then drop it into lots of boiling water to cook it.

• Blue crabs grow and reproduce quickly, but many populations are threatened by habitat loss from pollution and coastal development.
• In the Gulf of Mexico, there is high by catch of blue Crabs from shrimp trawls.

how do crayfish grind up there food in there stomach

Yes, according to some documentation I found online. There was a year, I want to say 2002 were there was lots of rain fall and crayfish were coming out of the river and into people's yards.

Where I am from in Northern California, in the only place I ever fished for them, I used a flyrod. My local shop told me to use a Calliabaetis dry fly (think that's how it's spelled) and I and my friend had good success, but this may be seasonal, as it was in September of the year and relatively warm. They like to hit close to the bank as opposed to rainbows or brookies who tend to range all over...hope this helps!

They will eat any and all flies, smaller fish, mice and even other trout.

Krill live in the southern oceans. but one type called the Antarctic Krill does live in of course the antarctic. Euphausia superba, makes up an estimated biomass of over 500,000,000 tonnes (490,000,000 LT; 550,000,000 ST), about twice that of humans. more than half is eaten by whales, seals, penguins, squid and fish every year, but they are replaced by reproduction. Most krill species have large daily vertical migrations, by doing this they provide food for many other animals.

There are no land animals on Antarctica.

The only danger to the sea life in the Southern Ocean that surrounds Antarctica is the natural danger afforded in any animal that is part of any food chain.

No. Vertebrates are only one phylum (Chordata), all the others don't have a backbone. Those are literally everything but fish, amphibians, reptiles, birds and mammals.

Unlike us humans with an internal or endoskeleton, the lobster relies upon its outer skin or exoskeleton both for support and for its armor. The internal organs are protected by this hard outer shell, made from chitin, a very tough protein used by other crustaceans and by insects. It is similar to the hard protein keratin in your fingernails and hair. You might also argue that the lobster is mostly protected by its own behavior - avoiding predators by hiding in crags. This is especially important when the lobster moults periodically, since the shell can't grow it has to shed it, then wait for the new shell to harden.

chelicerata have got 5 pairs of legs whereas crustaceans have 6 pairs.chelicerata have 2 pairs of antenae whereas crustaceans doesnt have antenae.chelicerates have uniramous appendages,crustaceans have biramous appendages.

Lobsters in the wild are generally mottled yellow, green, brown, and almost never red. The reason they turn red during cooking is that other pigmentations are broken down by heat, but the red pigments are not.

Lobster survival strategy involves a good deal of hiding from predators. They accomplish this by locating and occupying crags, hiding below rocks, and burrowing into the sea floor. They also have a highly acute chemical sense and have been shown to react to minute trace of chemicals indicating the presence of predators.

One might also argue they stay alive by blind luck. The vast majority of lobsters die before reaching adulthood; their reproductive strategy involves releasing tens of thousands of eggs. This is necessary since only one in ten thousand is estimated to survive long enough to end up on your dinner plate.

The lobster you might be used to seeing with the big claws is the american lobster (Homarus americanus), and lives off the east coast of North America, from below Maine up to Newfoundland. They are actually not red in the wild; the red color is a consequence of non-red pigments breaking down during cooking.

It depends on which artery. If your femoral artery is severed, you have minutes to live without immediate medical attention. Same for the Carotid artery in your neck, or the jugular vein in your neck. If the aorta artery feeding your heart goes, same thing. I would say the smaller the artery, the longer you may have to live before you bleed out.

The biggest life threat as far as arterial bleeds is the aorta. If any part of the aorta ruptures, a surgeon couldn't save you if he already had you cut open on the table. Essentially, if the aorta ruptures, it will only take about 3 beats of the heart to bleed out. The further away from the heart you get, the slower the bleed will be, but any compromised artery is potentially life threatening. The femoral artery in the thigh (the femur is the thigh bone, hence the name fermoral) is another big bleeder. The carotid is the second biggest life threat if it's compromised. So basically, if the aorta ruptures, 3 heart beats. If the carotid ruptures, perhaps 2 minutes. If the femoral is severed, perhaps 5 minutes. The difference is that the carotid and the femoral arteries can be controlled with proper treatment. The aorta is untreatable once it's compromised.

According to oxford dictionary a group of prawns is called Michelle

In the wild, prawns eat plankton, microscopic organisms that live in the water and include krill, algae, copepods and zooplankton. Prawns are scavengers, also feeding on decaying animal and plant matter.

Crayfish have an exoskeleton, meaning that their support structure is found on the outside of their body. The skeleton is composed of one large body covering that is scleritized (hardened) in some places and left unslceritized (flexible) in others to allow for movement at joints. Humans have an endoskeleton, meaning that their support structure is found internally. The skeleton is made of hard bones that are held together at the joints by ligaments and muscles.

Krill are a key component of the Antarctic food web, serving as a primary food source for many species including whales, seals, and penguins. While they play a crucial role, they are not the dominant herbivores in the Antarctic ecosystem, as there are other herbivorous organisms like algae and small fish that also contribute to the food web.

Crustaceans are well-adapted to life on the Rocky Shore because they have a hard shell, camouflage color-patterns, and strong claws. Crustaceans found on the Rocky Shore include crabs, lobsters, crayfish, shrimp, krill and barnacles.

Similarities: Daphnia and crustaceans (such as shrimp) share the same kind of "jerky" movement through a body of water. Also, like crustaceans such as lobsters and crabs, both have a hard outer shell.
