Mouth position

inferior

Distinctive features

Fleshy, branched tentacles (odontodes) on the snout of mature males, less developed or absent in females., Body covered in bony plates (scutes) instead of scales., Ventral mouth with a suckermouth disc., Prominent white or bluish-white spots over a dark body., Often possesses a white seam along the edges of the dorsal and caudal fins, particularly noticeable in juveniles and subadults.

Tail fin

Forked or emarginate, with the upper lobe sometimes slightly longer. The white seam is often very distinct here.

Identification Tips

1. 1

   Snout tentacles (odontodes)

   Males develop prominent, branched tentacles on their snouts, which are either absent or much smaller and unbranched in females. This is the most reliable sexual dimorphism.

2. 2

   Coloration and spotting

   The dark body with numerous small, bright white or bluish-white spots is characteristic. The white seam on the dorsal and caudal fins is also a key identifier, especially for distinguishing it from other Ancistrus species.

3. 3

   Eye color

   The striking blue eyes, particularly noticeable in younger specimens, can be a helpful, though not always definitive, identification feature.
