Macrognathus pancalus
Macrognathus belong to the family of proboscideans. This name they received for the unusual shape of the mouth: the upper jaw is elongated and pointed, forming a kind of proboscis. The genus name comes from the Greek words “macros” (large) and “gnathos” (jaw) and indicates their unusual mouth, which can stretch to swallow large food. Macrognathus are often marketed as eels, finches, and catfish, but they are a completely separate genus of fish.
Lead predominantly nocturnal lifestyle. Waiting for prey or resting during the day, prefer to bury themselves in the ground with their whole body, the head is left for observation. Also, regular burial allows you to remove excess mucus, which is constantly released on the skin of the fish. Powerful oslyzdenie also helps in case of accidental ingress to land, where the fish can exist for about an hour.
