καμηλοπάρδαλη comes from Ancient Greek καμηλοπάρδαλις
καμηλοπάρδαλις = κάμηλος (camel) + πάρδαλις (leopard)
This was also what they were originally called in English, camelopards. "Camelopardalis" is the genus name for giraffes, too.
"Giraffe", if you're wondering, is from the Arabic zarāfa.
And in Arabic lovely one is jameel or jameela and camel is jamal, so a lovely camel is jameel jamal (I hope:-)
I think it is more like καμηλο-πάρδαλη=spotted-camel and λεο-πάρδαλη=spotted-lion
Not by origin: "πάρδαλις: the pard, whether leopard, panther, or ounce" http://www.perseus.tufts.edu/hopper/text?doc=Perseus:text:1999.04.0058:entry=pa/rdalis
παρδαλός/πάρδαλη/παρδαλό has acquired the meaning "dappled" in modern Greek, but that came afterwards.

Το σκαντζόχοιρος τρώει τα γατοβισκότια μας is also an interesting concept. :-0 The hedgehog eats our cat biscuits. (Just experimenting!)
In most cases "the girrafe eats" would be ok. In this instance duolingo insists on "eating"...
