Description Lobsters are among the largest marine arthropods, with a long life span. They are slow growing animals with a
complicated and prolonged life cycle, which greatly increases the risk of stock depletion through indiscriminate
fishing. Sand lobsters are known to inhabit the open unconsolidated sediments between the coast and
adjacent reefs and further beyond. These animals prefer soft, muddy beds. They are nocturnal feeders, with
specific predatory feeding habits. Unlike the spiny lobsters, they swim actively and cover large distances while
foraging for food. Gross morphological modifications including dorsoventral compression of the body, lateral
expansion of carapace and extreme reduction of antennae and body spines have resulted in a well
streamlined, energy-efficient swimming shape. An insight into the reproductive biology of an animal is a preliminary
requisite for broodstock development and breeding in captivity. The intricate processes underlying the actual
phenomenon of propagation of a species usually begin at the formative phase of the individual. They however
manifest as visible changes at a later phase of growth, commonly acknowledged as the “adult” or “sexually
mature” phase. These processes include a number of anatomical, physiological, morphological and behavioral
changes.
