Bonesharks in the Mushroom Forest?

ROBOCOPMAX

Today, I went in a new session to the Mushroom Forest to farm some litium.
I get into my seamoth, arrive and BAM!
I encoutered at least three bonesharks in this forest.
But this kind isn't registerd to be found in the mushroom forest.
Can i just stamp this as a bug or do some of you have encoutered some bonesharks in this biome too?

I have a moon pool in the mushroom forest. The bonesharks are there and it is completely normal, but I don't know about that registration thing.
