There's a video I found on Facebook and I'm unable to figure out what the creature featured happens to be. Adding images that have been taken from the video itself, apologies in advance since they're not high qualify images.

Unknown creature

Unknown creature scaled using cigarette

Can anybody shed any light on what it is? The video was shot near Ratan Babu Ghat which is situated along the bank of Hooghly river, Kolkata, West Bengal, India. Here to be precise.
