Spotted Moray

The Spotted Moray is chiefly solitary, spending most of its day hidden within narrow crevices and holes in coral reefs or rocky substrates. Although active during daylight hours, individuals remain close to their shelters, poking only their heads out to survey for prey. They exhibit strong site fidelity, often returning to the same lair after foraging excursions. Movement involves a sinuous, undulating swim, allowing them to navigate complex reef structures with ease. While not migratory, they can traverse tens of meters nightly in search of food, relying on keen chemoreception and sensitive lateral line detection to locate hidden crustaceans, mollusks, and fish. Spotted Morays are non-territorial toward conspecifics outside breeding aggregations, but may display aggression if their lair is invaded. They are relatively shy around humans but can become conspicuous in aquarium settings when prey is offered.

Diet of the Spotted Moray consists primarily of benthic prey such as crabs, shrimp, small fish, and cephalopods. Using a rapid strike and powerful bite, they seize prey and draw it into their narrow burrows. Their double rows of sharp teeth and pharyngeal jaws enable them to clamp, manipulate, and process slippery prey effectively. Nutritionally, crustaceans and fish provide essential proteins, lipids, and micronutrients critical for muscle maintenance and energy storage. Ambush feeding reduces energy expenditure, while consumption of diverse prey items ensures a balanced intake of nutrients. They forage most intensely at dawn and dusk, matching prey availability, and may feed on up to three percent of their body weight daily. Occasional scavenging of carrion supplements their diet when live prey is scarce, aiding survival in variable reef environments. Digestive enzymes and efficient nutrient absorption enable rapid growth in juveniles and support reproductive investment in adults.

Reproduction in Spotted Morays is poorly documented, but like most moray eels they likely spawn pelagic eggs in open water. Courtship may involve synchronized swimming and tactile interactions near reef edges during night. Females release thousands of buoyant eggs that hatch into planktonic leptocephalus larvae, which drift with currents. No parental care occurs, and larvae metamorphose into juvenile eels before settling on the reef.

The Spotted Moray is classified as Least Concern, with a wide distribution across the Western Atlantic and Atlantic islands. Precise global population numbers are unknown due to cryptic behavior and inaccessible habitats. Local declines occur in areas of high bycatch and reef degradation, but overall stability is supported by their adaptability. Conservation measures include reef protection and bycatch reduction to ensure healthy populations in coastal ecosystems.
