Scientific Name:

Macrognathus aral

Species Authority:

(Bloch & Schneider, 1801)

Common Name/s:

English

–

Spiny Eel

Synonym/s:

Rhynchodella aral Bloch and Schneider, 1801

Taxonomic Notes:

Bloch and Schneider (1801) described Rhynchodella aral from Tranquebar. Roberts (1986) treated it under the genus Macrognathus. The species called aral in Sri Lanka is a separate species, M. pentophthalmos.

Assessment Information [top]

Red List Category & Criteria:

Least Concern ver 3.1

Year Published:

Assessor/s:

Vishwanath, W.

Reviewer/s:

Chaudhry, S., Britz, R., Allen, D. & Dey, S.C.

Contributor/s:

Molur, S.

Justification:

Macrognathus aral is considered to be Least Concern since it is very widely distributed and with limited threats. The species was earlier (1996, 1994) assessed, and the category changes from those assessments are due to new information.

History:

1996	–	Data Deficient
1994	–	Endangered (Groombridge 1994)

Geographic Range [top]

Habitat and Ecology [top]

Habitat and Ecology:	M. aral occurs in running and stagnant waters. Found in fresh and brackish waters and deltas of large rivers, common in ponds and slow flowing rivers with vegetation in plains. Inhabits still waters with silt or mud substrate. Believed to be common in rice paddy fields. Nocturnal feeder, on insects and worms.in lowland habitats and at moderate elevation in all the larger river systems of the Indian subcontinent.
Systems:	Freshwater
