Phreatobius sanguijuela is a South American species of heptapterid catfish that lives in underground waters.[1]
This species was first discovered in a hand-dug well located within the Paragúa River drainage, a tributary of the Guaporé (Iténez) River in Bolivia.[1] Later it was discovered just across the border in several wells near São Francisco do Guaporé in the Brazil ian state of Rondônia.[2] This species is threatened by environmental degradation due to pollution, water extraction for drinking and irrigation, mineral extraction, and associated erosion.[1] It is often killed when accidentally caught from wells because of a superficial resemblance to leeches.[1]
This small fish reaches a maximum standard length of 4.2 cm (1.7 in).[1] P. sanguijuela differs from P. cisternarum in a number of ways, but the main differences are the absence of eyes (which are present in P. cisternarum).[1]
