Crab hermit with anemone - specimens sunk in the material

MACHINE TRANSLATION (not authorised yet)

The transparent plastic block is filled with natural specimens - a hermit crab in a shell with an anemone attached to it. This is one of the best known examples of symbiosis (protocooperation) between two organisms, here: the hermit crab and the anemone. A hermit who protects his body (soft abdomen) in an empty shell provides the anemone with transport and food leftovers, and in return, the anemone's anemone's anemones provide protection. It is interesting that when the hermit changes the shell, the anemone "moves" with him.
The block is packed in a bubble pocket and placed in a lockable cardboard box. Dimensions of the didactic aid: 8.5 x 6 x 2.5 cm.
