The family Scyliorhinidae is the largest shark family, with at least 15 genera and over 100 species. Their common name, catsharks, likely derives from their elongated, cat-like eyes, although their scientific name is based on the Greek words, “Scylla,” meaning “a shark,” and “rhinos,” meaning “nose.” Some members of Scyliorhinidae are also commonly known as dogfish. Members of this family tend to be small, usually less than 1 m long, and are harmless to humans. Most catsharks live in seas above the upper continental slope, a location that makes it difficult to observe these sharks and collect specimens. Therefore, much information about catsharks remains to be discovered.
