Myrichthys ocellatus, commonly known as the Gold-spotted snake eel, is a species of ophichthid eel found in the western Atlantic Ocean. It is characterized by its elongated, snake-like body and distinctive pattern of golden or yellow spots, often ringed with black, against a pale background. These eels are benthic, inhabiting sandy or muddy substrates where they burrow, often leaving only their heads exposed. They are nocturnal predators, primarily feeding on small crustaceans and fish. While generally reclusive, they are not considered dangerous to humans unless provoked.
Physical Characteristics
- Body shape
- eel-like
- Coloration
- Pale white to yellowish or light brown background with numerous distinct, circular to oval golden-yellow spots, often outlined in black. The spots are typically larger and more prominent on the dorsal side, becoming smaller ventrally. The head also features similar spotting.
- Scale type
- none
- Mouth position
- terminal
- Distinctive features
- Elongated, cylindrical, snake-like body, Absence of pectoral fins, Small, conical head with a pointed snout, Distinctive pattern of golden-yellow, black-edged spots
- Dorsal fin
- Long, low dorsal fin originating behind the head and confluent with the caudal and anal fins.
- Tail fin
- Pointed, hard, and fleshy caudal fin, confluent with dorsal and anal fins.
- Pectoral fin
- Absent
- Distinctive fins
- All fins are continuous, forming a single fringe along the body, with no distinct pectoral fins.
Identification Tips
Spot Pattern
Look for the characteristic golden-yellow, black-edged spots covering the entire body. The size and density of these spots are key.
Body Shape
Its extremely elongated, cylindrical, and snake-like body, typical of ophichthid eels, is a strong indicator.
Absence of Pectoral Fins
The lack of pectoral fins is a definitive feature for Myrichthys species, distinguishing them from many other eel families.
Snout Shape
A relatively short, pointed snout with anterior nostrils tubular and posterior nostrils opening into the mouth.
Habitat
- Water type
- saltwater
- Depth
- Typically found in shallow coastal waters, from the intertidal zone down to about 50 meters (164 feet).
- Environment
- Prefers sandy or muddy bottoms, seagrass beds, and rubble areas near coral reefs. They are fossorial, spending much of their time buried in the substrate.
- Geographic range
- Western Atlantic Ocean, from Florida (USA) and Bermuda, throughout the Caribbean Sea, including the Gulf of Mexico, and south to Brazil.
Aquarium Information
- Care level: intermediate
- Temperament: semi-aggressive
- Diet: carnivore
- Minimum tank size: 120 gallons
- Temperature: 72-78°F (22-26°C)
- pH level: 8.1-8.4
- Hardness: 8-12 dKH
- Compatibility: Best kept in a species-specific tank or with large, robust, non-aggressive fish that cannot be swallowed. Avoid small fish, crustaceans, and other eels.
- Special requirements: Requires a deep sand bed (at least 6 inches) for burrowing. Tank must be securely covered as they are expert escape artists. Provide ample rockwork for hiding and exploration. Live foods or frozen meaty foods are essential for their diet.
Wild Information
- Conservation status: least concern
- Seasonality: No specific seasonal patterns for abundance or breeding are widely documented; they are present year-round within their range.

Key Facts
Burrowing Behaviorbehavior
Gold-spotted snake eels are highly fossorial, spending most of their day buried in sand or mud, emerging primarily at night to hunt.
Mimicryinteresting
Their snake-like appearance and burrowing habits are thought to be a form of mimicry, deterring potential predators.
Absence of Pectoral Finsamazing
Unlike many other fish, Myrichthys ocellatus lacks pectoral fins, which is a characteristic adaptation for their burrowing lifestyle.
Nocturnal Hunterbehavior
These eels are primarily nocturnal predators, using their keen sense of smell to locate prey hidden in the substrate.
Safety Information
Handle with care- Safety level: caution
- Venomous: No
- Edibility: not recommended
- Handling notes: While not venomous, Gold-spotted snake eels can deliver a painful bite if provoked or handled carelessly. Their skin is covered in a protective mucus, and handling them can remove this, making them susceptible to infection. Always exercise caution and avoid direct contact if possible. If bitten, clean the wound thoroughly.
Similar Species
Sharptail snake eel
Myrichthys breviceps
M. breviceps has a similar body shape but typically exhibits fewer, larger, and more irregularly shaped dark spots or blotches, rather than the distinct golden-yellow, black-edged spots of M. ocellatus. The spots on M. breviceps are often more brown or black and less vibrant.
Spotted snake eel
Myrichthys maculosus
M. maculosus, found in the Indo-Pacific, has a similar spotted pattern but the spots are typically dark brown to black and lack the distinct golden-yellow coloration and often the black outline seen in M. ocellatus. Geographic range is also a key differentiator.
