Expedition blogs and news from the Shallow Marine Surveys Group

New records are pouring in.

With so many divers in the water each day, it is no surprise that new records for Ascension Island are pouring in almost daily.

In 1980, Roger Lubbock compiled a check-list of the fishes of Ascension Island. Since then, quite a few new fish records have been accumulated, in particular by island residents and visitors Jimmy Young and John & Jane Bingeman. We are planning to update the fish list and additionally produce a number of publications on the invertebrates discovered during the expedition.

The sea anemone, Telmatactis cricoides, was known from St Helena island but not yet from Ascension.
