Yes, some species of lobster can be cannibals, though this would never be the most important mode of feeding.
European and American clawed lobsters (Homarus gammarusand Homarus americanus), which are probably what most people will think of as 'the lobster', will prey upon smaller individuals of their own species if they are brought into close proximity. This can happen in lobster traps, for example, but in most cases the smaller individuals take care to avoid larger lobsters. Norway lobsters (Nephrops norvegicus), also known as scampi, langoustine, Dublin Bay prawn, ..., will certainly prey upon juveniles of their own species, and this is one factor thought to constrain the numbers of young added to the population when adults are dense on the ground.
Cannibalism may be less prevalent in rock lobsters (perhaps someone else can confirm this)? Some species will actually aggregate rather than avoid one another.
Technically, yes they are shellfish. However, for regulatory purposes, they don't fall under this classification. They are crustaceans; exoskeleton-bearing aquatic invertebrates that are used as food.
Yes.

The secondary consumers, such as lobsters, feed on the herbivores. The tertiary consumers, in turn, feed on the secondary consumers, and so on.
Studies of wild lobsters show that they prefer live prey, such as fish, mollusks, worms and crustaceans, but surgeonfish and lobster don't hang out in the same environments. Lobsters are are bottom feeders found in the cold waters of Alaska and Maine, while surgeonfish are herbivores that prefer warmer coral reefs and feed on algae, you will find them near rocks that get a lot of filtered sunlight.
Red lobsters are one of them, the other being the green lobsters
Lobsters are not decomposers. They are consumers.
Lobsters are crustaceans and are also aquatic. (life in the water)
Lobsters typically don't eat their own young, but they will eat baby lobsters from other parents. Lobsters often eat their old shell.
No it does not appear that Lobsters live in the Nile. Lobsters tend to live at the bottom of the ocean.
No, lobsters do not eat coral
