Reproductive Biology

Separate sexes, with males spawning into the water and females releasing eggs after fertilizing them. Larvae must be capable of dispersing to new vents since vents are ephemeral habitats.

CONSERVATION STATUS Not listed by the IUCN.

SIGNIFICANCE TO HUMANS "Posterchild" of hydrothermal vents. ♦
