One of the more colourful creatures found on the ocean floor, sea slugs or nudibranchs (naked gills) are a favourite for divers and photographers. There are 3,000 species worldwide and the Pacific Northwest has over 200 species ranging in size and colour.
Nudibranchs are found at every dive site in the Campbell River region and certain species can be more seasonal providing some interesting dive opportunities. From the very common Noble Sea Lemon to the Giant Rainbow Dendronotids, these marine invertebrates feed on an assortment of creatures. Often the nudibranchs take on the colour of their prey and in some cases the natural defence system of some stinging cell creatures like anemones are transferred to the nudibranchs that consume them.
