Common sawfish

The common sawfish, Pristis pristis, is a sawfish of the family Pristidae, found in tropical and subtropical parts of the Atlantic, Mediterranean, eastern Pacific and in northern Australia.[1] As suggested by its name, it was once plentiful, but has now declined drastically leading to it being considered a critically endangered species by the IUCN.[1] Its maximum length is 7.5 metres (25 ft), though 2.5 metres (8.2 ft) is more common.[2] Reproduction is ovoviviparous.

Its taxonomy in relations to P. microdon and P. perotteti has caused considerable confusion, but recent evidence strongly suggests the three are conspecific (in which case P. microdon and P. perotteti are synonyms of P. pristis), as morphological and genetic differences are lacking.[3] Three main clades based on NADH-2 genes were evident (Atlantic, Indo-West Pacific, and East Pacific), but these do not match the distributions claimed for P. pristis (circumtropical), P. microdon (Indo-West Pacific) and P. perotteti (Atlantic and East Pacific) respectively.[3]
