This is another that really needs no introduction. They're another one I wrote up a long time ago because they're cool. I do think some natural threats in a game world should be a problem for PC's but be unlikely to result in a life or death situation. Of course if you have a whole shoal of these each take a bit out of the PC's and then swim off at high speed that could be immensely dangerous!

The thresher is a 10' long silvery grey shark, capable of immense speed. Around half of its body length is composed of a long, thin dorsal tail fluke. Its favoured form of attack is to move in at huge speed, take a bite from a victim, and escape. When attacking thus, it has a +3 bonus to surprise a victim, and it will typically immediately try to escape the following round. Deaths due to thresher sharks are thus uncommon, but horrific injuries may result.
