Lost River Shark?

[Brittlebullet]

So I noticed this card on the Trello from the Machine Update https://trello.com/c/nXBuwu3f/5472-implement-lost-river-shark

Is this for the Spine eel that's supposed to be in the lost river or is there something else I missed that's going to be down there?

I haven't seen anything about a new species just for the Lost River but if you look at the other biomes, many have re-skinned versions of existing fish. Another Trello card, for example, shows the Lava Zone versions of the Eye-eye and the Boomerang (reddish colored). So maybe it's just a slightly different version of the Bone Shark or Sand Shark?

There is supposed to be a new version of the bone shark in the lost river I remember hearing awhile back.

It's just a reskin of the existing boneshark, like what was done with the lava boomerang and eyeye.

Honestly, I thought it was the Spine Eel for a minute. Then I remembered:
IT'S A ♥♥♥♥♥♥♥ EEL, NOT A SHARK.
