Definition
Callechelys muraena is a species of marine fish belonging to the family Ophichthidae, commonly known as worm or snake eels.
Overview
Callechelys muraena was first described by Jordan & Starks in 1905. It is a benthic eel inhabiting tropical and subtropical coastal waters, typically associated with sandy or rubble substrates where it can burrow. The species is recorded in the western Pacific region, including waters around Japan and the East China Sea. Like other ophichthid eels, it is presumed to be a nocturnal predator feeding on small fish and invertebrates, although specific dietary studies for this species are lacking.
Etymology / Origin
The generic name Callechelys derives from Greek roots: “kalle” meaning “beautiful” and “chelys” meaning “tortoise” or “shell,” a name historically applied to snake‑like eels. The specific epithet muraena references the classical name for moray eels, reflecting a perceived similarity in appearance.

Taxonomy:
- Kingdom: Animalia
- Phylum: Chordata
- Class: Actinopterygii
- Order: Anguilliformes
- Family: Ophichthidae
- Genus: Callechelys
- Species: C. muraena
-
Morphology: Members of the genus typically possess an elongated, serpentine body lacking scales, with a pointed tail adapted for digging. Specific morphological data (e.g., total length, coloration patterns) for C. muraena are not comprehensively documented in publicly accessible literature; thus, accurate measurements are not confirmed.
-
Habitat and Distribution: Recorded from marine coastal environments of the western Pacific. Precise range limits and depth preferences are not fully verified.
-
Reproduction and Life History: Detailed reproductive biology for C. muraena has not been described in peer‑reviewed sources; typical ophichthid reproductive strategies involve oviparity with planktonic larvae, but species‑specific confirmation is lacking.
