Up UK Diving » Seasearch Sponge ID Course - Plymouth May 08 » Sponge course dives

The course fitted in a dive each day, from Fort Bovisand on Saturday and Phoenix quay on Sunday. We were searching out sponge samples but there was plenty of time to see other good stuff. What we mostly found out was how hard it is to tell sponges apart, many appear in lots of widely different shapes and lots look very similar and can only be told apart by microscopic analysis of their tiny 'spicules' - which are extremely attractive but invisible to the naked eye. So really the most important discovery was how little we knew.
