Giant crab spiders have such a ferocious appearance that they earned a spot as extras in the horror film Arachnophobia. These creatures, however, eat only cockroaches, crickets, and caterpillars, more than compensating for their scary appearance. Giant crab spiders are about 2 inches long, are hairy, and have noticeable black fangs and black feet. Their egg sac is the size of a golf ball.
