Macrognathus pavo is a member of the spiny eels family Mastacembelidae

Characteristic features
As their name suggests spiny eels have
  • elongate, eel-like body
  • long dorsal fins along their backs
  • 4 - 42 strong sharp spines on dorsal fins
    • when caught, these fishes can wriggle backwards driving the spines into their attacker.
  • long snouts or trunks
    • highly sensitive
    • used to probe around for insects and worms
Macrognathus pavo is the least spiny of the spiny eels with 4 to 6 dorsal spines only. Most spiny eel species have many more dorsal spines, up to 42.
Macrognathus pavo belongs to a group of eleven closely related species, the Macrognathus aculeatus group.Macrognathus pavo differs from the other members of the group in
  • its colour pattern
  • smaller number of rostral tooth plates on the underside of the trunk.
    • these tooth plates probably help the fish to grab their prey

  • Species name
    • Comes from the Latin word “pavo”, peafowl, referring to the numerous black spots found on the species.
