Bullhead

Heterodontus quoyi goes by many names: in English it is known as the Galapagos Bullhead shark or the Peruvian Horn Shark (the latter because of it’s spines in front the first and second dorsal fin). It is one of the most elusive species of sharks that has recently come into the attention of researchers. Despite having been around since the late Jurassic, very little is known about the Galapagos Bullhead Shark. It has been classified as ‘Data Deficient’ under the IUCN Red List of Threatened Species, the most dangerous category to be in.
