How do lobsters stay alive?

Answer 1

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.

Answer 2

After mating the female lays eggs, which hatch into drifting larval forms, which often become part of drifting plankton. Slowly the larva will develop into a full lobster to stop drifting and settle into its final form and habitat.
