Gymnothorax gracilicauda, commonly known as the slendertail moray, is a species of moray eel found in the Indo-Pacific region. This relatively small eel can reach a maximum size of 32.0 cm and is commonly found at depths ranging from 6.0 to 20.0 meters.
Description & Characteristics
The Gymnothorax gracilicauda is characterized by its slender body, particularly its elongated tail. This species exhibits a brown coloration with darker brown blotches along its body, providing effective camouflage amongst the coral reefs it calls home.
Habitat and Occurrence
Gymnothorax gracilicauda is primarily found in the Indo-Pacific region, inhabiting the warm, tropical waters of this vast expanse. This species is particularly common in coral reef environments, showcasing a strong preference for these vibrant ecosystems. They thrive in shallow reef zones, generally ranging from 6.0 to 20.0 meters deep. These depths provide ample opportunities for foraging and shelter within the complex structures of the reef.
Taxonomy
The species Gymnothorax gracilicauda belongs to the Class: Teleostei, Order: Anguilliformes, and Family: Muraenidae. This classification places it within the group of ray-finned fishes, which are distinguished by their bony fins supported by rays. As an anguilliform, it is part of a group that includes eels and conger eels, known for their elongated, serpentine bodies. Finally, the Muraenidae family encompasses the moray eels, which are characterized by their powerful jaws, sharp teeth, and generally lack of pectoral fins.
Feeding
Gymnothorax gracilicauda is a carnivorous predator, relying on a diet of small fishes and invertebrates. Its sharp teeth are well-suited for seizing and consuming these prey, allowing it to effectively hunt within its reef environment. Its ambush hunting strategy involves concealing itself amongst the coral, waiting patiently for unsuspecting prey to come within range.
