Painted Spiny Lobster's Behavior & Ecology
Growth in spiny lobsters, as in many crustaceans, is impacted by biotic and abiotic factors, including water temperature, food availability and quality, salinity , and injury. In addition, growth is often slower for larger individuals that devote more energy to reproduction. Such factors may influence how lobster growth changes via either intermolt interval or molt increment . Size at maturity is, in turn, tightly coupled to patterns of growth. As a result, size at maturity not only varies between species, but between regions as well.
Painted Spiny Lobster's Feeding
It is a carnivorouse animal which is nocturnal and feeds on both carrion and fresh caught arthropods, other crustaceans, and occasional small fish.
