You may very well be right. I didn't look into it to much. I'm no expert on them. As tbtb said to be sure of the exact species I'd have to read a little as well, while I'm a little familiar with the group not so much. I trust kno4te though so agreed with him. But we can all be wrong from time to time. Thanks for the brief explanation in why you think that's the correct speciesI agree with cogs. Google images shows that it is more likely to be neosilurus ater than a tandanus tandanus. Neo have narrower mouth.
