Chitala chitala

Chitala chitala (Bengali: চিতল, Assamese: চিতল "sitawl", Tamil: அம்பட்டன்வாளை, சொட்டைவாளை or அம்புட்டன் வாழ) is a knifefish from Bangladesh, India, Nepal and Pakistan,[1] where found in the Indus, Ganges, Brahmaputra and Mahanadi River basins.[2] It is sometimes known as the Indian featherback/knifefish.[3] In the past it frequently included several related Chitala species, but these are now regarded as separate species.[2][4] The main species confused with this species is C. ornata (clown featherback or clown knifefish); a Southeast Asian species seen regularly in the aquarium trade.[3] The true C. chitala is very rare in the aquarium trade.[3]

Description
Chitala chitala in Assam, India. Notice the stripes to the back and the dark spots on the lower rear part of the body (both relatively indistinct)

Chitala chitala reaches a maximum length of 122 cm (48 in), but more commonly reaches about 75 cm (30 in).[2] It is overall silvery in color. Unlike all its relatives, it usually (but not always) has a series of golden or silvery bars along the back, resulting in a faint striped appearance.[3][4] Additionally, it has a series of fairly small, sometimes indistinct, non-ocellated dark spots towards the far rear of the body (at the "tail"). This separates it from C. ornata, which has ocellated spots (dark spots surrounded by a paler ring) and lacks bars along the back. The two species have frequently been confused.[2][3][4]

As food

Chital machher jhol or Chitala fish curry is a regional delicacy in Indian state of West Bengal and in neighbouring country Bangladesh.[5]

In religion

This species is based on Hinduism beliefs. It is one of the avatars of Lord Narayana (Vishnu), in the first episode titled "Matsya" that Narayana was born as a golden knifefish to kill the demon.[6]
