# Red Sea Clingfish (*Lepadichthys erythraeus*)

**Taxon:** Clingfishes (*Gobiesocidae*)  
**Conservation Status:** LC - Least Concern  


The Red Sea Clingfish, scientifically known as Lepadichthys erythraeus, is a small and fascinating fish species native to the biodiverse waters of the Red Sea. This particular clingfish is part of the family Gobiesocidae, known for their unique adaptation that allows them to cling onto various surfaces in their marine environments.

ypically measuring up to 4 centimeters in length, the Red Sea Clingfish is frequently observed in proximity to sea urchins. One of its most distinguishing characteristics is the ventral sucker disc, which is an adaptation derived from modified pelvic fins. This unique feature allows the clingfish to secure itself to a range of substrates, including rocks, coral, and even larger marine organisms. Such an adaptation proves critical in navigating the Red Sea's robust currents and wave dynamics.
