I recently found myself competing with a friend over who could name the most animal adjectives (the 'ine' ones, although as you can see they're not all 'ine'). I'm not sure why. Anyway, I'm grateful to have stumbled across this comprehensive list from an interesting piece about the influence of Latin on English:
ant/formicid, bee/apian, bird/avian, crow/corvine, songbird/oniscine, cod/gadoid, carp/cyprine, fish/piscine, gull/laridine, wasp/vespine, butterfly/papilionaceous, worm/vermian, spider/arachnidan, snake/anguine, turtle/testudinian, cat/feline, rabbit/cunicular, hare/leporine, dog/canine, deer/cervine, reindeer/rangiferine, fox/vulpine, wolf/lupine, goat/caprine, sheep/ovine, swan/cygnean, duck/anatine, starling/sturnine, goose/anserine, mongoose/herpestine, grouse/tetraonine, ostrich/struthionine, horse/equine, chicken/gallinaceous, cattle/bovine, pig/porcine, agouti/dasyproctine, whale/cetacean, kangaroo/macropine, ape/simian, frog/batrachian, bear/ursine, man/human or hominid (gender specific: man/masculine, woman/feminine)
I used to wonder if snake went with "supine". But apparently not. The actual snake adjective is lovely.
There is one animal whose absence from this list is rather glaring, of course.
