Description

Meet the Paulasteriidae: a new family of seastars (starfish), including the first seastar species known to thrive at deep-sea hydrothermal vents. This video was recorded by the UK's Isis ROV (remotely operated vehicle) at a depth of ~2400 m (~1.5 miles) on the East Scotia Ridge in the Southern Ocean near Antarctica (latitude ~60 degrees South), during Voyage 42 of the RRS James Cook in 2010. Formal scientific description of the new family of seastars, and this new Antarctic vent species (Paulasterias tyleri) was published in April 2015: Mah C, Linse K, Copley J, Marsh L, Rogers A, Clague D & Foltz D (2015). Description of a new family, new genus, and two new species of deep-sea Forcipulatacea (Asteroidea), including the first known sea-star from hydrothermal vent habitats.
