Vertical distribution correlates with pressure tolerances of early embryos in the deep-seaasteroid Plutonaster bifrons
The astropectinid asteroid Plutonaster bifrons (Wyville Thomson) occurs on the continental slope of the north-east Atlantic between 1000 and 2500 m depths. As in most deepsea animals, the factors limiting bathymetric distribution of this species are unknown. Eggs were fertilized in vitro and incubat...
