Hyalopterous Lemure and Mystic Remora are really funny parallels to each other because they were both originally printed in Ice Age with comically misdrawn art. although they sound like gibberish, both "hyalopterous" and "lemure" are real words; the former means "having transparent wings", and the latter is a form of spirit or ghost from Roman religion. however, Dick Thomas made the same mistake as Google here and drew a hyalopterous lemur
since "lemur" and "lemure" are both different, real words, WOTC was pretty easily able to correct this one with a reprint. they also printed another Lemure in Time Spiral, mostly as an excuse for some Norin the Wary flavor text:
Mystic Remora, on the other hand... you know, i always thought it was weird that something as creature-like as a fish would count as an enchantment instead of a creature, but i (embarrassingly) recently learned that "remora" can also mean "drag" or "resistance" (apparently out of the belief of sailors that remoras stuck on their ships increased drag). this makes way more sense with the card type and effect than a fish. unfortunately, "remora" and "remora" are not different words[citation needed], and by the time the card was up for a reprint, it was because it was such a powerful and iconic EDH card that suddenly "fixing" the art would be way more trouble than it was worth. so they've kind of just rolled with it lmao
woe, fish be upon ye
