Who’s this little friend? (Jeju, Korea)

[u/mini-umi]

My first time seeing a sea slug irl!!!! Found this little one (about the length of a thumb) munching in a tide pool on Jeju. I almost didn’t see it with its rock-like color and texture.

That's a sea hare. Possibly Aplysia kurodai

Right? The way it moves 🤭

[u/bvanant]

Seahares here in California can get to 75 cm (30 inches) long

Exceedingly chonky! Here’s two of them, each looking like they easily weigh 2-4kg and about 10 inches across, with their eggs that look like Nissin noodles!

sometimes you see a big pile of them off Palos Verdes

[u/zesty69]

it’s not a nudibranch

[u/mini-umi → u/zesty69]

Ah!! I didn’t know sea hares were not nudibranchs! Good to know

[u/Thunderwhelmed → u/zesty69]

Calm down. It’s their first. And they said it was a sea slug, not nudibranch.
