Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
This species is distinguished by the following characters; extremely elongate; head 4.6% TL; tail 52.3% TL; body depth at gill opening 1.1% TL; predorsal-fin length 58.4% HL; snout length 10.9% HL; lateral-line pores anterior to anus 104; vertebral formula 4-103-224; and dorsal-fin origin slightly behind middle of head and above fourth lateral-line pore. Colouration: body bicolored, no bands on head (Ref. 127464).
Cross section: oval.
The single specimen was collected by a trap net operated by a local fisherman who targeted glass eel species of Anguilla. It was collected together with other snake eels, such as Lamnostoma sp. and Ophichthus sp., and was probably chasing the fish larvae to the river mouth (Ref. 127464).
