Event details

Brittlestars or ophiuroids are close relatives of the starfish you find in rock pools along Britain's shores and can be found in many marine environments, including the deep sea where they are often important contributors to the sea-floor community.

The deep sea covers a vast proportion of our planet yet is poorly understood and new species are continually being discovered. The brittlestars in this talk were found in a recently discovered crater in the Antarctic deep sea, close to an area of active hydrothermal vents. The brittlestars are probably new species, with nothing being known about their ecology. This talk explores their ecology for the first time, including their population structure, reproduction and diet. The continual discovery of new species, such as these brittlestars from the Antarctic deep sea, demonstrates how little we know about this fascinating environment and just how much there is left to discover.

 

Further information

This talk is open to members of the public, staff and students. Admission is free.

Visitors attending the talk should arrive at the National Oceanography Centre Southampton at 7.15pm to be met in Reception

The National Oceanography Centre Southampton can be reached via Dock Gate 4 (between Town Quay and Ocean Village).

The talks are accessible via stairs or a lift. Since the lift cannot be used in an emergency, evacuation of less able visitors is down the stairs via an evacuation chair. You are therefore required to notify us in advance of the presence of a wheelchair user or anyone with access issues likely to require use of an evacuation chair.
