Clarias planiceps explained

Clarias planiceps is a species of clariid catfish from Borneo. It is known from tributaries all over Sarawak, and possibly up to Kapuas Hulu Regency.

Habitat & distribution

It can be found in slower parts of relatively fast-flowing streams with mud or sand as substrate. The holotype has been described from Belakin, with paratypes found all over Sarawak's first, second, and third division[1]

Characteristics

Collected in 1994, the holotype was noted to be of 106.5 mm in length (10.65 cm) from skull to caudal fin, with 97 corresponding paratypes ranging from 46.9 to 297.3 mm (4.7–29.73 cm), therefore possibly including juveniles. The diagnosis of this species are defined by the following characters:[1]
