Etymology: Ghost shark is the name for a group of chimaeras, cartilaginous fishes more closely related to sharks than to bony fish, that live in deep water and have pale, almost translucent bodies. Despite the name, they are not sharks at all. Their lineage split from the shark line hundreds of millions of years ago, and they are sometimes called rabbit fish or ratfish for their long tails and large eyes. The compound is simply the two plain English words "ghost" and "shark" placed side by side, with "ghost" describing the pale, hard-to-see body and "shark" naming the closest familiar animal. Writing it as one word, "ghostshark", is an alternative form of the two-word spelling "ghost shark."

Synonyms: chimaera, ratfish, rabbitfish, elephant shark, hydrolagus
