The majority of verified records submitted to the Great Eggcase Hunt were from the south coast of England (in particular the eastern English Channel) with some records from southwestern coasts. Material examined. Fifty-two eggcases were examined in detail, most of which were collected by the Great Eggcase Hunt (n = 50), while the other specimens (n = 2) were from public aquaria. An additional aberrant specimen collected in January 2015 from Brighton (English Channel) was also supplied to the Great Eggcase Hunt for examination (see below). Description.
