ungulata fu'ivla

x1 is an ungulate/member of clade Ungulata, of taxon/subclade/species/breed x2.

Includes cetaceans (being hooved/ungulated per se is not required); use "selsfu" for the sense of "hoofed animal" (a narrower description if discourse is restricted to currently-extant Terran fauna).

In notes:

selsfu
x1 (probably but perhaps not necessarily an animal) is hooved/has hoof/hooves x2 (body-part).
