The story of the forest snakehead

A widespread Southeast Asian snakehead of forest swamps, slow streams, lakes and ponds, often among plants and sunken wood; an important food fish, sold fresh and often alive.

Georges Cuvier described this snakehead in 1831. Its long, pike-like body gave it the name 'lucius', the old Latin word for pike.

First described by Georges Cuvier in 1831. Named for 'Lucius' recalls the pike, after its long shape.

  • It has a row of dark blotches along its sides.
  • It lives in shaded forest waters.
  • It is a medium-sized snakehead, typically under 40 cm.
