NUDIBRANCHS UPDATE ~ INCREDIBLE FACTS AND VIDEOS

Since I first posted “NUDIBRANCHS – SAY WHAT?”,  May 14, 2012), I’ve found the time to delve further into these fascinating and exotic ocean creatures.  You will be thrilled and amazed with the facts shared on these YouTube videos and the awesome video footage from around the world (Indonesia, Philippines, Bali)

First a few very interesting facts:

Nudibranch ~ means “naked gills”
Nudibranchs ~ are sea slugs
~ are beautifully colored tiny vessels of danger
~ store toxins/stinging cells they steal from their prey
~ more than 3,000 species
~ range in length from 1/4 inch to over 1 foot
~ are hermaphrodites (meaning they have both male and female sex organs)
~ are found in oceans from Antarctica to the tropics

I won’t overload you with information, for as they say, “a picture is worth a thousand words”.

“Nudibranchs”, by Jean-Michel Cousteau, Ocean Adventures ~uploaded by on Dec 5, 2008 ~ “They might be tiny, but nudibranchs can pack a poisonous punch. Learn more about these extraordinary creatures”.

 

This next video is amazing ~ the music, “The Tahiti Trot” is very artistically adapted to the bizarre antics of the nudibranchs  ~ an award winner in my opinion!!!

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.
