With 2024 approaching, here's another guessing game, this time about the natural world and its denizens.

Rules

Any animal extinct or alive is allowed.
Bacteria and single celled organisms aren't allowed.
You are allowed ask up to three questions per post (but please do it sparingly every round).
Rounds are allowed to go on for two days after the round's start, but if everyone is stumped, the OP can reveal it, and goes to the person who declares stumped first.
Please put the common name and scientific name when you reveal the answer for extant species.
- Note that I said Extant; extinct species usually have no common name, so put the full scientific name.
Images are recommened.
