Here we discover can a lobster swim backwards? If you look carefully at the rear end of a lobster you will see that it spreads out into a scoop-like structure called a tail fan. Normally, of course, the lobster walks over the bottom or, if in a hurry, it can swim forwards using special swimming legs on its tail up underneath its body and paddles its way backwards out of danger at considerable speed.
Shrimps, prawns and freshwater crayfishes also have a tail-fan and so all these crustaceans can swim backwards in this way. Another thing they have in common is that they are all enjoyed by man as food.
Lobsters provide a lot of meat from the muscles in their large pincers and from the abdomen. The Spiny Lobster is found in both the southern Atlantic and Pacific Oceans. Europe produces the common European and the Norway Lobsters, the latter known as scampi.
Can prawns change colour?
There is one prawn that is particularly good at changing its colour. This is the Aesop Prawn. Normally it is pink but it can vary its body colour to match that of its surroundings. This usually occurs in times of danger when a predator is lurking nearby.
If it takes refuge on brown seaweed it gradually turns brown and on green seaweed it turns green. Strangely enough at might it always turns blue, no matter what colour its surroundings happen to be. The colour is produced by pigment cells all over the prawn’s body.
