How does a slugs digestive system work?
Sea Slugs feed on a wide variety of different foods. Some are herbivores, feeding on sea weeds and other marine plants and others are carnivores, each species feeding on very specific food items.
Their digestive systems have evolved different features to cater for the different foods they eat.
I have prepared a page for you on the digestive system of a dorid nudibranch which is a pretty good example of how a slug's digestive system works.
For more information have a look at the General Topics Index for interesting pages and use the Search Button for more information. Try searching for food or feeding, and perhaps for gizzard, because many sea slugs have a gizzard with crushing plates to 'chew up' their foodbefore it reaches the stomach.
