Freshly-baited crab traps are lowered on a metal platform to the sea floor.

We lower a metal platform, called an elevator, loaded with freshly-baited crab traps down to the sea floor in order to catch deep-sea spider crabs. Most of the crabs captured here were juveniles. This is great for our study, because the hormone levels will span a wider range, giving us more insight into growth and reproduction. Image courtesy of Jeff Pollack
