Echelus
Echelus is a genus of snake eels, belonging to the family Ophichthidae. These eels are commonly known as “worm eels” or “snake eels” due to their elongated, serpentine body shape, and are found in tropical and subtropical waters worldwide.
Characteristics
Echelus species typically possess the following characteristics:
- Elongated Body: They are known for their very long, slender bodies that lack pectoral fins.
- Small Head: Their heads are relatively small compared to their bodies.
- Sharp Teeth: They have sharp, pointed teeth that are well-suited for catching prey.
- Dorsal and Anal Fins: They have a long, continuous dorsal fin and a long anal fin that extends along the entire length of their bodies.
- No Pelvic Fins: Echelus eels lack pelvic fins.
- Burrowing Behavior: Many species of Echelus are burrowing eels, meaning they spend much of their time hidden within sediment.
- Nocturnal Habits: They are generally nocturnal, becoming more active at night.
Environment
Echelus eels are found in a variety of marine environments, including:
- Coral Reefs: Some species inhabit coral reefs, where they can find shelter and food.
- Seagrass Beds: Other species prefer seagrass beds, using these areas for foraging and hiding.
- Sandy Bottoms: Many species inhabit sandy bottoms, burrowing into the sediment to escape predators and ambush prey.
Diet
Echelus eels are carnivorous, feeding primarily on small invertebrates such as crustaceans, polychaete worms, and other small fish.
Reproduction
Echelus eels are thought to be oviparous, meaning they lay eggs. The details of their reproductive cycle are not fully understood.
