- gall developing on acorn 1

This is not a sea bean or even a seed, but a gall of a seed, the acorn. The gall, Knopper Gall is caused by the wasp Andricus quercuscalicis, which inoculates acorns of oak trees with its eggs. The galls become detached from the acorns or fall with the acorns into rivers and streams where they are brought to the sea and washed-up on beaches.

Specimen above found on the strandline at Gwithian, Cornwall. 10.03.16.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help
people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
