Scuba Diver And Yellow Boring Sponge

Scuba diver observing yellow boring sponge among sea weeds on flat silty bottom of Mahurangi Harbour, New Zealand.

Note: Reviewing these pictures from a couple of years ago I am wondering how clear the water in the harbor used to be. Or perhaps it’s just I don’t dive there often enough to experience it at its best. Also if I remember well the pictures were taken in winter when the visibility is usually better … if it’s not after a period of rain.
