Sponges; Porifera

Sponges are especially popular with our scuba diving macro photographers. Both for their fine structure but also as food sources for a few of our Koh Phangan Nudibranch species.

The largest and most eye-catching of all the sponges, with a variety of growth forms.

Haliclona species - maybe caerulea - food of the Jorunna nudibranch.

Growing over all sorts of things...

With a growth form more plant-like than anything else, here's another atypical sponge!

You would never guess that this beautiful structure was actually a sponge!

Including Black, and Golf or Tennis Ball Sponges.

Quite possibly 1 or 2 of these are actually Ascidians ie Sea Squirts...
