Also:
porcine - pertaining to pigs
ovine - pertaining to sheep
caprine - pertaining to goats (hence caper and capriole)
piscine - pertaining to fish
lapine - pertaining to rabbits
aprine - pertaining to pigs, but used to refer to wild pigs/boars/related species rather than domesticated suidae (hence "caput apri defero"; "the boar's head in hand bear I")

Not all such zoological adjectives take the -ine ending; the next most common one is -ian, as in:

Some nice obscure ones:

also, although "avian" refers to birds in general, you have:
columbine, of or pertaining to doves and pigeons (while many places named Columbus, Columbia, etc., are named after Christopher C., many others are named after the goddess who is the personification of peace, sometimes called Columbia, and she in turn was named after the dove that represents peace.)
