Hunting Pygmy Squid
This is the same Two-toned Pygmy Squid - Idiosepius pygmaeus which I found in a tidal pool during low tide.
It was swimming around, changing its colour from light to dark depending on where it is near to.
The size of the body is around 1 cm and with the tentacle extended, is around 2.5 - 3 cm.
