The sixgill sawshark, Pliotrema warreni is a sawshark of the family Pristiophoridae. Presence of six pairs of gill slits highlights this genus among sharks; outside Hexanchiformes order, Pliotrema is the only shark genus with more than five gill slits. Unlike other sawsharks, the barbs on this shark's rostrum continue onto the sides of the head. Its barbels are also closer to its mouth than in other species. At maximum, females can reach over 136 cm long, and males can reach over 112 cm long.

Barbodes is a genus of small to medium-sized cyprinid fish native to tropical Asia. The majority of the species are from Southeast Asia. Many species are threatened and some from the Philippines are already extinct. A survey carried out in 1992 only found three of the endemic Barbodes species, and only two were found in 2008.

Paramphilius is a genus of loach catfishes found in Africa.
The tropical sawshark, Pristiophorus delicatus, is a recently described species of sawshark, family Pristiophoridae, formerly known in literature as Pristiophorus sp. B. It is endemic to northeastern Australia, found on the upper continental slope off Queensland from south of the Samaurez Reef, at a depth of 246–405 meters (807–1,329 ft). Its specific epithet delicatus is Latin for "delicate", referring to the fine teeth on its saw-like rostrum.

Garra geba is a species of cyprinid fish in the genus Garra. It is endemic to Ethiopia.
Mesonoemacheilus menoni is a species of ray-finned fish in the genus Mesonoemacheilus. It is endemic to the southern Western Ghats in Kerala, India, where it occurs in the upper reaches of the Periyar River over substrates of cobbles, pebbles and sand in flowing water. It is common within the Periyar Tiger Reserve but may be threatened by predation and competition from the invasive African cichlid Mozambique tilapia, the common carp and Clarias gariepinus.
