This red-white-and-blue shrimp was among the distinctive animals scientists found on a recent survey of French Frigate Shoals in the Northwestern Hawaiian Islands.

With its conspicuous blue eyes and shiny orange claws, this colorful crab seems hard to miss. But it’s one of many species that had likely never been seen until scientists went exploring in the Northwestern Hawaiian Islands Marine National Monument this fall.

This shrimp belongs to a species thought to have died out some 50 million years ago. Caught at a depth of 1,300 feet (400 meters), the new species is described as a “living fossil”.

Isopod crustaceans include both rare and abundant species. Unfortunately, finding different kinds of isopod species is like searching a needle in a haystack for researchers. Fortunately, this peculiar little one was found.

The “yeti crab,” discovered on the floor of the Pacific Ocean, is so extraordinary that a new taxonomic family had to be invented for it. The new species was found during a deep-sea dive expedition, some 900 miles (1,500 kilometers) off Easter Island. Living next to hydrothermal vents at depths of 7,540 feet (2,300 meters), the blind white crustacean, named Kiwa hirsute, was also dubbed the yeti (or abominable snowman) crab because of its hairy arms, which support colonies of yellow bacteria.
