Hydrolycus scomberoides

Hydrolycus scomberoides is part of the Hydrolycus species and are characin members of the Neotropical fishes in subfamily Cynodontinae.

The big fangs they have are a main characteristic of this species and although they might seem to be an adaptation for feeding behavior, no casual mechanism can be infered. Long canineform teeth and their oblique mouth help make the species distinctive. Their looks remind one of the deepsea fishes found in the world's ocean. The swimming angle is also bizarre and is reminiscent of the characin head standers.

They can reach at least 650 mm SL.

Hydrolycus scomberoides is restricted to the Rio Amazonas and its tributaries above mouth of Rio Tapajós.
