Re: Scientists - Dry bites
Yes eventually they do. A dive buddy (who worked in underwater videography), found a largish King Cobra wrapped around his toilet. So he tied his camera to a broomstick and decided to annoy it, first it made a threat display, then it starting dry striking the lens, after a few hits then it started using venom (you could see it on the lens), after a few more strikes it seemed to use a lot more venom.
Snakes will dry bite as a threat, because most animals aren't stupid enough to stay around and they want to conserve the venom, but they absolutely will use it if they feel like they are in danger and their opponent isn't backing down.
It also depends on the snake some snakes are mellower than other species, sea snakes are really chilled and yet almost all species are highly venomous I have never felt worried encountering one, I wouldn't fuck around with a black mamba though one African lady described them to me as "an extremely angry snake." *
Also it does not need to be adult a baby snake is born fully venomed and are said to be more dangerous as they have less control over there bites.**
*There was a beeb prog on rattlesnakes and the researches said even individuals among the same species had different temperaments.
**Recently seen an article somewhere saying this may not be true but have not read it yet.
