Note on collection method: Lately we have devised a method of finding very small nudibranchs on small rocks from intertidal zones.
We refer to this method as ANAEROBIC EXTRACTION which simply involves placing the encrusted rock into a bowl of sea water and waiting until the animals are drawn out. The rocks are carefully replaced following the procedure.
We closely observe the rocks as the oxygen content of the sea water decreases and the animals make their way off the rock towards the surface where the oxygen levels are higher and where they can be more easily identified and collected.
They are collected by use of a pipette.
We observe and photograph using our Prism Optical Zoom trinocular, stereomicroscope with a digital camera attached to the third tube and remotely controlled via a P.C. The specimens are placed in a viewing dish of suitable background contrast (usually black or white depending on animal colour)
The combination of this collection method and the microscope photography has proved rewarding with new species being encounted every time we use the procedure.
