Cetopsorhamphidae

Cetopsorhamphidae is a family of freshwater catfishes found in South America. These fish are characterized by their elongated bodies, a flattened head, and a wide mouth. They typically possess three pairs of barbels, which are sensory appendages used for detecting food in their environment.

The members of Cetopsorhamphidae are primarily nocturnal, meaning they are most active at night. During the day, they tend to hide in crevices, under rocks, or among submerged vegetation. Their diet consists mainly of small invertebrates, crustaceans, and other small fish.

Currently, the family Cetopsorhamphidae contains only one genus, Cetopsorhamphus, and a single described species, Cetopsorhamphus diphrysi. This species is known from the Amazon Basin, inhabiting rivers and streams. Further research is ongoing to better understand the diversity and evolutionary relationships within this family.

Due to their limited distribution and specific habitat requirements, conservation status assessments for Cetopsorhamphidae are important. Factors such as habitat degradation and pollution can pose threats to their populations.
