Giant crabs make Antarctic leap


The crabs are large and dominant organisms, able to crush other animals

King crabs have been found on the edge of Antarctica, probably as a result of warming in the region, scientists say.

Writing in the journal Proceedings B, scientists report a large, reproductive population of crabs in the Palmer Deep, a basin cut in the continental shelf.

They suggest the crabs were washed in during an upsurge of warmer water.

The crabs are voracious crushers of sea floor animals and will probably change the ecosystem profoundly if and when they spread further, researchers warn.

Related species have been found around islands off the Antarctic Peninsula and on the outer edge of the continental shelf.

But here the crabs (Neolithodes yaldwyni) are living and reproducing in abundance right on the edge of the continent itself.

Search for life

The researchers sent the Genesis, a submersible remotely operated vehicle (ROV) from the University of Ghent in Belgium, into the Palmer Deep in March last year.

The idea was to look at what life was down there, rather than specifically to look for crabs; and the team was somewhat surprised by how many they found.
