Common Names
Heteroconger eels are commonly known as "garden eels" due to their habit of living in large, dense aggregations that resemble gardens. They are also known as "spaghetti eels" because of their long, slender bodies.
Characteristics
Heteroconger eels are characterized by their long, slender bodies, which can reach up to 1.5 meters in length. They have small heads with large eyes and small mouths. Their dorsal fin extends from the head to the tail, while the anal fin is located on the ventral side of the body. They possess a single, long fin that runs the length of their body. The color of Heteroconger eels can vary depending on the species, but most are a mottled brown or yellow.
Environments
Heteroconger eels are typically found in shallow, tropical and subtropical waters. They inhabit sandy or muddy bottoms and often congregate in large groups. They are mostly found in the Indo-Pacific, with a single species known from the Atlantic. They prefer to live in areas with moderate currents and good visibility. They are often seen in close proximity to coral reefs, seagrass beds, and rocky outcrops. They are known to live in burrows in the substrate, usually with their heads exposed, which allows them to feed and keep an eye out for predators.
