Scientists have discovered a new species of giant amphipods, or shrimp-like animals, in one of the world’s deepest ocean trenches. The Kermadec Trench is found off of the northern coast of New Zealand. The largest of the amphipods is an amazing 11 inches (28 centimeters) long. “Amphipods are common to deep-sea trenches, but they’re usually 2 to 3 centimeters [about an inch] long. They turn up in a matter of minutes like a swarm of bees and simply devour all of the bait,” said Alan Jamieson, a marine biologist at the University of Aberdeen and co-leader of the expedition that found the animals.
