Images taken by a friend yesterday (1-25-25):

These shots were taken by me, today, 1-26-25. Barnacle Billie was resting in a cave when I encountered her; :

I carefully grabbed the material coming out of her colaca to see what it felt like and a piece broke free with no real force exerted.After I surfaced, she opted to surface for air.

She went down and took a couple bites of turbinaria

Back to the cave to rest:

I kept a sample of what seems to be a thin membrane with shell bit and other mass on its surface. It felt rubbery in the water but tears very easily

Other side of film:
