According to the Sci-Fi network, all you need to solve the problem is a ruggedly handsome, tough as nails military officer who has a problem with authority, a beautiful and brilliant young scientist whose unconventional theories have yet to be accepted by the scientific community, and a young, geeky computer genius who can make any electronic device surrender to his talents. Add a bunch of disposable red-shirt type marines and you're good to go no matter what animal poses a threat.
Personally, I'd stock up on a bunch of
Holy Hand Grenades.
