Ipnops

Ipnops is a genus of deep-sea fish in the family Ipnopidae, also known as the telescopefishes or grideyes. The defining characteristic of Ipnops species is the presence of flat, plate-like structures on the top of their heads which function as eyes. These structures are not conventional eyes, however. While they are capable of detecting light, they are believed to be primarily used to detect bioluminescence from above, aiding in prey detection or predator avoidance.

Ipnops species are small, typically reaching lengths of around 8-10 centimeters. They are found in deep ocean environments across the globe, typically at depths of 800 to 1,800 meters. Their bodies are elongated and somewhat flattened, and they lack scales. They also possess long pectoral fins.

The diet of Ipnops is thought to consist of small invertebrates that live on the seabed. Their method of feeding is largely unknown due to the difficulty of observing them in their natural habitat.

The taxonomic classification of Ipnops includes several species, though the exact number and validity of each are subject to ongoing research. Commonly recognized species include Ipnops murrayi.

Due to the remote and deep-sea habitat of Ipnops, relatively little is known about their behavior, reproduction, and overall role in the deep-sea ecosystem. Further research is needed to fully understand these fascinating creatures.
