How do crabs have sex

Hermit crabs are a common sight scuttling across warm beaches, but many of these charismatic crustaceans wield something surprising and hidden—very large penises, sometimes half the length of their shell-anchored bodies. New research suggests the crabs evolved such outsized organs to help them mate without straying far from home. These animals can whittle their shells and secrete erosive chemicals, allowing them to create a smooth and expansive interior. These refurbished homes give them space to grow and may even provide room for egg storage—making the shells extremely valuable.

Penis Size Matters for Hermit Crabs Trying to Keep Their Shells During Sex

By Jim Giles. The discovery of the sex-for-security trait helps to explain a surprising quirk: how it is that females defend their territory just as successfully as males despite their smaller claws. It is also the first known case of male and female neighbours teaming up to defend territory in any species, according to lead researcher Richard Milner of the Australian National University in Canberra. Fiddler crabs live in burrows and often fight to protect them from would-be squatters.

How can you tell if my Hermit Crab is a boy or a girl? - Sea Shell Shop, Rehoboth Beach, Delaware

The sexual behavior of the hermit crab Coenobita compressus was studied. The size, gastropod shell species, and sexual behavior of males measured in terms of successful or unsuccessful mating assessed by spermatophore transfer are compared, as well as the role of these variables in male-male encounters for the access to females. Since female receptivity assessed as degree of egg development could also influence male mating success, the relative number of receptive and unreceptive females that had or did not have spermatophores is used to evaluate whether unreceptive females were induced to mate. We assessed how frequently receptive and unreceptive females were present in the population. An experiment determined if males were able to grab females according to female sexual receptivity.
