"Diaphanous bags"

You see these diaphanous bags all over the reef.  What are they?

Thank You,

Diaphanous Bag

The object in the center?  Is it a parrotfish case?

I don't know

I don't know what it is; I'm asking you.  Is it a parrotfish case?  It was daytime.  Do parrotfish just discard their "sleeping bags" each morning? 

Thank You,

Marty

Parrotfish Sleeping Bags - I like that

Marty, Scientists don't know for sure if parrotfish can consume their cocoons in the morning.  However, if disturbed in the middle of the night, they will abandon the cocoon.
