Short description आकृति विज्ञान | मौरफोमैटरिक्स

This species is distinguished by the following characters: tail length as measured from cloaca much longer than disc width or length (means: tail length 53.7% of TL, vs. disc width 40.3% of TL and disc length 42.1% TL); nasal curtain much wider than long; colour pattern dorsally uniform light yellowish-brown, which is also present over preorbital snout region, no distinctive spotting or markings over disc and tail; low and inconspicuous lateral tail ridge, not resembling a distinct fold; mean preorbital snout length just over 10% of TL (Ref. 93928).

Usually found over sandy and muddy bottoms (Ref. 93928). Maturity size reaches at ca. 24 cm TL; born at ca. 7-8 cm TL. Biology little known (Ref. 114953).
