Wildlife that proper freaks me out, like:

Dolphins, and whales. Especially Killer Whales [the clue is in the name!]; those white ones with heads like dildos that live near Greenland; and ones who are so big you only see them emerge, like shiny islands, above the surface of the water for a couple of seconds before disappearing completely.... no, wait, THERE'S A TEN FOOT LONG TAIL ABOUT TO SPLASH YOU.
Urgh, I don't trust these nasty fake-mammals at all. I'd rather swim with sharks- at least they are up front about their intentions.

Butterflies. Pathetic, I know, but I cannot get the thought out of my head that these so-called 'beautiful' insects want nothing more than to get tangled in my hair and then feel all flappy. Urgh.

Sammies. Sammies have 8 legs and provoke such terror in my soul that I cannot type the real word, or even dwell on the reasons why they freak me out.

Monkeys that look really human. Wrong. Never cute.

Babies.
