Caprid is very obscure taxonomic terminology. Let's rename it to Goat.
The Caprid taxonomical grouping is slightly broader than Goat, being its family of cousins that are also known as goat-antelopes, but the one and only Caprid profile is a goat. They're all close enough to Goat that the character can happily just call themselves an uncommon cousin of the goat, and mark themselves as a goat - or an antelope if they feel their goat-antelope is more antelope-ish than goat-ish; we're not taxonomy experts, we're here to find profiles to play with. I'm sure the Goaty caprids and the Antelopey caprids will appreciate the plain language, as will everyone interested in them who aren't deeply invested in taxonomic terminology.
(Looking at our bovid profiles there is also a Ram who might be a sheep or a goat. Since sheep =/= goats and it isn't useful equating them, I've suggested a sheep species.)
