Sponges and what else from Cozumel

[designbysue]

I saw a lot of this sponge(?) in Cozumel.

1. What is the common name for these purplish things?

2. What is the white net-looking thing in the upper left?



Thanks
Sue

Anyone have any idea? (Trying to complete a video with id subtitles and this one is still missing)

Here is another image

and a zoom in

Closest thing I can think of is white condominium tunicates or an overgrowing tunicate of some sort.

Just found this one that makes it look like nd encrusting sponge, though the other pics are more blob like

and here is another shot but not sure these are the same


I saw these (all 3 kinds) through Cozumel and in the previous 2 trips never saw them. Hope the new pics helps someone id these.

What is an overthrowing tunicate - I can't find anything about them?

Looks something like Sea Pork, possibly a form of Amaroucium stellatum.

Interesting!

I searched for Sea Pork and

Amaroucium stellatum hoping I could find a picture to confirm but all I could find is pictures on the surface.

Over growing. I hate autocorrect.

Over growing. I hate autocorrect.

That is getting some promising images from a search now - you may be correct.
