A team from the University of Alabama at Birmingham will sail around Antarctica for three weeks to study the movements of king crabs. The researchers are concerned that the crabs are moving up the Antarctic slope toward the shelf because of warming waters and will shake up the ecosystem there. "These crabs, they're like skeleton-breaking crabs, they feed on sea stars and things like that, so they have the potential to really change the ecosystem at the bottom of the ocean," said C.J. Brothers, a Ph.D. student who is part of the team. "We're worried that as they move towards a new spot, they're going to be eating basically everything in their path."
