Reproductive pattern and egg development of the deep-sea crab Paromola cuvieri (Brachyura, Homolidae) around the Canary Islands (NE Atlantic)
This work investigated the biology of Paromola cuvieri in the Atlantic Ocean, including reproductive patterns, sex structure, depth distribution and egg development. Females were more abundant than males, mainly at depths greater than 600 m. Males were dominant in size classes larger than 110 mm car...
