They may exhibit minimal migratory behavior. Larger, more mobile, adult lobsters may inhabit deeper waters and may return seasonally to shallow warmer waters. Female lobsters can carry live sperm for up to two years. At any time she may decide to fertilize her 3,000-75,000 eggs. By law, a female lobster carrying eggs must be thrown back if it is caught.
Lobsters come in just about every color but red.
They can be blue, light yellow, greenish-brown, grey, dusty orange, some calico, and some with spots. However, they all turn red when they hit hot water. The hot water cuts the link between astaxanthin, a red substance contained in the lobster's shell, and protein which in cold water brings out the predominant coloring. They can discard a limb, this can be a lifesaving phenomenon. Lobsters have the ability to regenerate some of their body parts, for example, the claws, walking legs, and antennae.
