Microdesmidae
Microdesmidae is a family of eels within the order Anguilliformes. Commonly called “dwarf eels” or “pygmy eels”, they are found throughout the world’s tropical and subtropical oceans.
Characteristics
These eels are small, typically less than 10 cm long, with elongated bodies and a single dorsal fin that extends from the head to the tail. Their eyes are small and often covered with skin, and they have a unique feature: a single, barbel-like projection beneath their chin. Microdesmidae possess a unique combination of features, including their small size, elongated bodies, and a single barbel-like projection beneath their chin, which distinguishes them from other eel families.
Environments
Microdesmidae are primarily found in shallow waters, typically inhabiting coral reefs, rocky shores, and seagrass beds. They are often found in crevices or under rocks, where they can hide from predators. They are typically found in shallow waters, often in close association with coral reefs and seagrass beds.
Diet
Dwarf eels are carnivores and their diet primarily consists of small invertebrates like crustaceans and polychaetes. Their small size and barbel-like projection under their chin likely help them in finding and capturing their prey in tight spaces.
