Coelacanth

The coelacanth is like a fish that time forgot, kind of like a dinosaur but with fins. Imagine a chunky, prehistoric creature that looks like it got lost on its way to a rock concert. It has lobed fins that are more like arms, making it look part fish, part awkward amphibian. Its skin is scaly and kind of lumpy, with a color scheme that screams "I live in the deep dark ocean, and I don’t need fashion advice." It’s been hanging around for roughly 400 million years, just chilling in underwater caves like a reluctant hermit. Overall, it's like the ancient relative of fish that decided to skip evolution for a few eras.
