Both the male and female hermit crab produce inviting sex pheromones. The males are very aggressive during breeding and are known do be quite dominant over the females. [ 13 ] The Pagurus novizealandiae ' s behaviours around the transfer of sperm will be unique to the species but the process will still involve lining up gonopores [ 8 ] on the ...
Male hermit crabs will compete with other males for available females during breeding season. P. longicarpus , like many crustaceans, performs precopulatory mate-guarding behaviors, where males will grasp ahold of the female's shell once the female releases a pheromone signaling sexual maturity.

A hermit crab emerges from its shell, Coenobita perlatus Outside its shell, the soft, curved abdomen of hermit crabs, such as Pagurus bernhardus, is vulnerable. Hermit crab species range in size and shape, from species only a few millimeters long to Coenobita brevimanus (Indos Crab), which can approach the size of a coconut and live 12–70 years.
They reproduce through indirect sperm transfer between male and females. Courtship rituals involving touch and smell are common before mating. [8] Like other hermit crabs, they cannot make their own shells and instead they most often live in discarded snail shells. [9] Multiple Redleg calcinus have been observed sharing a single shell. [10]

Clibanarius tricolor is a hermit crab that lives in shallow water of the Caribbean Sea and is popular in the home aquarium trade. Its common names include blue-legged hermit crab, tricolor hermit crab, [1] blueleg reef hermit crab, equal handed hermit crab and blueleg hermit crab.
Like other hermit crabs, Clibanarius vittatus lives inside the empty shell of a gastropod mollusc. This protects its soft abdomen and normally only its head and limbs project through the aperture of the shell. The chelipeds (claw-bearing legs) and claws of Clibanarius vittatus are small, both the same size, and covered in short bristles. When ...
