Feather Starfish is acting like an alien

[batoo]

First time it came out

The night of the same day

The last 1min Video was just shot. I never expected a feather starfish could have an individual part just like a serpent, yet it’s extremely sensitive to light. Seems doing great

Since I introduced it to my tank, this feather star haven’t lost arms for like 80 hours now. But this ‘serpent’ came out like 30hours ago, the shell seems to be less active since. Can’t confirm the shell is still alive or just the nerves are dying. Anyone know anything about this?

Couldn’t find any possibilities of symbiotic relationship between the serpent and the feather starfish. Idk can feather starfish’s arm still swinging 30hours long after died?

Wierd. The mouth of the larger one is still there and the one that came out has a mouth, could that have been a second one that was piggy backing on the first the whole time? I couldnt find much on how they reproduce, (edit: or whether they have dimorphism) only that its sexual reproduction.
