Spiny lobsters do not have the gonopods (first pleopods modified for reproduction) that occur in clawed lobsters and crabs, and females do not have a deep pocket on the sternum in which to store sperm. [11] Instead, a spermatophore is transferred directly from one of the male's gonopores to the sternum of the female. The male gonopore is ...

The eggs have an average diameter of 1 millimetre (0.039 in). The eggs are generally surrounded by the extraembryonic membranes but do not develop a shell, hard or soft, around these membranes. Some fish have thick, leathery coats, especially if they must withstand physical force or desiccation. These type of eggs can also be very small and ...

William Elford Leach erected the genus Megalopa in 1813 for a post-larval crab; a copepod post-larva is called a copepodite; a barnacle post-larva is called a cypris; a shrimp post-larva is called a parva; a hermit crab post-larva is called a glaucothoe; a spiny lobster / furry lobsters post-larva is called a puerulus and a slipper lobster post ...
