The members of this order lack a rasping "tongue" (radula) and feed by secreting digestive enzymes and then absorbing the resulting nutrient "soup". This is very similar to the way starfish eat!

They can all retract their gills.

Dendrodoridae



Some Dendrodoris species with tubercles have mantle secretions that cause painful stings.

Dendrodoris tuberculosa

Phyllididae



Although the main gills have disappeared in this order, the pouch in which they could be retracted remains. A secondary set of gills exists under the mantle.

This group are extremely toxic due to the isocyanides that they take from their prey. The isocyanides can be secreted into the surrounding water is stress situations.

Help Save Reefs!



The organisations that work to protect coral reefs and our oceans need as much support as they can get. Check out:

If you are a diver, and especially if you are an underwater photographer, donate. If you do nothing, there will be nothing to dive on and nothing to photograph.

These are suggestions, but not endorsements of the suggested organisations. It is your responsibility to review and check the charities you wish to donate to.
