Range Extension of Omobranchus punctatus (Valenciennes, 1836) from Sunderban Biosphere Reserve, West Bengal, India

West Bengal lies in the Northernmost part of peninsular India and has a rich variety of aquatic ecosystems such as hill streams, ponds, rivers, mangroves, mudflats, estuarine creeks, and small riverine channels which holds a large ichthyofaunal diversity of as much as 610 species of which a total of 350 species is harbored at Sunderban Biosphere Reserve, a jeweled crown of the southernmost estuarine and marine ecosystem of West Bengal. The present work reports the first record of one blenniidae, viz. Omobranchus punctatus (Valenciennes, 1836) from Sunderban, West Bengal, India. Morphometric data, live coloration and specific habitat details of the collected specimens are detailed here.
