The Naked Sea Slugs 



ish, dotted with black, and often roughly tuberculated. It 

 rarely exceeds three inches in length. Look for it at low tide in 

 shallow pools or in tangles of seaweed. It is worthy of study 

 in a jar of sea water. 



It is a diverting thought, and an enlightening one, that these 

 helpless creatures are protected by the expedient of wearing 

 their arborescent "liver and lights" on the outside. Sea ane- 

 mones are known as bad-tasting creatures, with projectile stingers 

 which they cast at the least suspicion of attack. Hence, resem- 

 blance to anemones is a strong defence to any nudibranch. One 

 little slug carries an anemone on its back. Many feed upon the 

 anemones they imitate, often hiding in the capacious bodies 

 they devour piecemeal. Those that feed upon ascidians, sea 

 fans, hydroids and corals imitate in their branching cerata the 

 tentacles of these creatures, as well as their colouring.
