NUDIBRANCHS – “SAY WHAT?”

 I really don’t know what I’d do without my e-mail account.  I’ve just discovered interesting information that I’d like to share with you about another amazing colourful mollusc-like marine creature, known as a “nudibranch” (pronouced NEW-dih-bronk) 

“Just what are nudibranchs?”, you might ask.

The nudibranchs are ocean bottom-dwelling, shell-less mollusks featuring featherlike gills and horns mostly found on their backs and are part of the sea slug family. They are noted for their often extraordinary colors and striking forms.

Nudibranchs are usually oblong in shape and measure anywhere from ¼ inch to 12 inches.

Nudibranchs are carnivores that graze on corals, anemones, algae, barnacles and sponges. To identify prey, Two extremely sensitive tentacles (‘rhinophores’) on top of their heads help them locate their food sources., called rhinophores, located on top of their heads.

The colour of the nudibranchs is retained from the food they digest.  This colouring and poisons they keep from their prey help the nubdibranchs protect themselves from predators.

Nudibranchs lifespans vary with some living under a month, and others living up to one year.

  1. I’ve been surfing online more than 2 hours today, yet I never found any interesting article like yours. It’s pretty worth enough for me. In my opinion, if all site owners and bloggers made good content as you did, the net will be much more useful than ever before.

  2. Keep functioning ,great job!
