SEA SLUGS. 



By Then. Curreras. 



Although ill senetal form and movement the Slugs of the Sea remind us of the Slut:;s of the Land, the former are more richly coloured and 



decoraied ihan their relatives of the field and f^arden. This ornamentation serves the purpose of hiding them from their enemies by 



harmonizini; with their surroundings. Much of it is attained in the plumed and crested forms by wearing part of their liver in these 



appendages, which thereby take oh the colour of their food. The Slut^s are here shown about five times their natural size.
