Synanceja trachynis
[ TOC ]
Image found too large...please help us acquire a smaller image...extremely poisonous oceanic rock fish...be very careful!
Identification
Family: Scorpaenidae
Scientific Names: Synanceia trachynis [Note: There are >1,000 currently named species in at least 67 current genera in this boney-fish Family (Scorpaenidae). This is one of 3 current very similar-looking species in this genus which can cause severe human envenomations & fatalities. The other 2 are Synanceja horrida & S. verrusosa.

Common Names: Stone fish, goblin fish, nofu, warty-ghoul, rock fish, lump fish, poison fish, scorpion fish

Description
Usually mottled greenish-brown (often w/ red or gray flecks/ blotches), many stone-like bumps & flap-like projections over most of its body make it very hard to detect in typical resting sites. Body relatively large, rounded in front, tapers to much smaller, rounded tail, eyes dorsal, w/ 13 grooved poison-dispensing spines within the dorsal fin, each w/ a pair of venom glands, & more such spines in the relatively short, wide pectoral & anal fins.

Habitat
Found mainly in moderately shallow (mainly marine, sometimes brackish) waters above coral reefs or in near-shore coastal shallows usually over at least partly sandy bottoms. Widespread along the coasts of nearly every country that borders the Indian & southwestern Pacific Oceans (not yet reported from some), mainly north of the Tropic of Capricorn & mainly south of the Tropic of Cancer.
Activity and Behavior
Typically rest on the bottom among protruding coral knobs, & any bottom plants or animals (e.g., sponges, annemonies), usually in water <20 m deep. Often lie partly hidden under sand & bottom debris. Can live out of water for many hours. Usually ambush & eat mainly smaller fish & marine arthropods that pass by them.
Venom Characteristics
Very potent neurotoxin w/ cytotoxic & possibly hemolytic factors (some spp. also have hyaluronidase & pre-synaptic transmitter blockers). Venom of most spp. is unstable at pH <5.5 or >9.0, & at temperatures above 50 degrees C. Spines can usually penetrate sand shoes when the fish is stepped on (or gloves when handled). Numerous human envenomations & deaths have been documented.

Bro It could be a lot useful if you could include Bangla names for these snakes. I have no business with these tons of English and scientific names.

GB wishes this was his thread.

Currently there is no Bangla name for most of these snakes.

Therefore I request all of you to propose Bangla Names (please refer post #s as there are so0 many of them). This is your chance to famous in snake kingdom.

[layperson]

Is this a new way of increasing your post count BK bhai ? I cant think of any other reasons for this thread and the sheer number of posts you have made here.

Nice post, BK. Back in the 70's, when Dhaka wasn't yet that much of a concrete jungle, and there were still many dobas and pukurs around, one often encountered snakes, and occasionally hired shapuraes (snake-charmers) to get rid of them. I remember becoming quite friendly with one shapurae who showed me some of his pet (venom-sac removed) snakes -- he had a live albino cobra, the only "white" one that I've ever seen.
