DNA barcoding adjudicate two different morphs of Bascanichthys deraniyagalai (Anguilliformes: Ophichthidae): re-description and first record from Chilika lagoon, India

Figures & data

Figure 1. (A) Whole-body specimen of B. deraniyagalai collected from Chilika lagoon. (B) NJ tree of the studied eel species with bootstrap support. A. rostrata of Family Anguillidaeis used as an out-group in the phylogeny. Green and orange bars represent the two known subfamilies of family Ophichthidae. Two morpho-groups of studied B. deraniyagalai were showed by pink and blue voucher ID and accession numbers. (C) Line diagram of B. deraniyagalai. (D) Dental pattern of B. deraniyagalai.

Table 1. The between and within-species K2P genetic distance of the studied eel dataset.
