The largetooth sawfish (Pristis microdon), also known as the Leichhardt's sawfish or freshwater sawfish, is a sawfish of the family Pristidae, found in shallow Indo-West Pacific oceans. As its relatives, it also enters freshwater. This species reaches a length of up to 7 metres. Reproduction is ovoviviparous. Recent evidence strongly suggests P. microdon is synonymous with P. pristis. Consequently, the IUCN removed P. microdon from their list, instead recognizing it as part of the critically endangered P. pristis. Order: Pristiformes, Family: Pristidae, Species: Pristis microdon Latham, 1794. |
