Chimaera

A rarely seen chimaera, spotted during the dive on the southeast side of Johnston Atoll on September 17, 2015. Chimaeras are most closely related to sharks, although their evolutionary lineage branched off from sharks nearly 400 million years ago, and they have remained an isolated group ever since. Like sharks and rays, they are in the cartilaginous fish group. They have a series of pores running along their snouts that are electrosensors used to help them find prey.
