I was going to say the same thing as the very wise 3kitties . the hyphen in animal-like delineates that there are two words and that they should be pronounced as two distinctive words. Otherwise it would sound, and I am using JFW with Eloquence, animallike, which is not right. But you cannot say animal like because that doesn't mean the same as animal-like. Plantlike and Funguslike do not have the two l's and as such do not need to be hyphenated.
Get it? Got it? Good. :)
