- Polychaete worms and sea cucumbers. Part 23 of my DVD, "Reef Life of the Andaman", available at www.bubblevision.com/marine-li... or view the whole 2-hour video at • Reef Life of the Andam...
First we look at a feather duster worm, Sabellastarte sp., at Shark Cave in the Burma's Mergui Archipelago, and a hard tube coco worm, Protula bispiralis, at Richelieu Rock, north of the Similan Islands in Thailand. These polychate worms are rooted statically to the reef and feed by filtering plankton from the water with their tentacles and passing it into the central mouth.
Colorful Christmas tree worms, Spirobranchus giganteus, are common at many dive sites throughout the Andaman Sea. They embed themselves into porous stony corals and are highly sensitive to disturbances. At the slightest sign of danger, the worm retracts into the coral and seals the opening.
Also seen in the Mergui Archipelago, the large burrowing sea cucumber, Neothyonidium magnum, a type of Echinoderm, is another filter feeder. It roots itself into the substrate and holds its outer tentacles in the current. When it has captured sufficient plankton the tentacles reach down toward the centre, allowing the smaller inner tentacles to scoop the food into the mouth.
The Graeffe's sea cucumber, Pearsonothuria graeffei, is common at shallow depths in the Andaman Sea, for example at dive sites around Racha Yai. Its mouth contains 25 adhesive black tentacles which it uses to walk over the reef and to pick up food from the substrate.
The mouth of the amberfish sea cucumber, Thelenota anax, contains 18 tentacles and is underneath the body. After digesting what it can from the material it has ingested from the seabed, the waste products are expelled at the anus. The sea cucumber also breathes through the anus by sucking water in and out.

The video was shot by Nick Hope with a Sony VX2000 DV camera in a Gates housing. It was edited in Sony Vegas Pro then deinterlaced with QTGMC and upscaled to 720p HD in AviSynth.

Amazing! Never knew feather stars were a kind of worm! :O Always thought they were an underwater plant!
es realmente precioso.la naturaleza en el mas bello estado de expresion no hay nada comparable con ella sobretodo bajo el mar me gustaria poder disfrutarlaa directamente y admirar cada lugar recondito y oculto es impresionante.gracias por enviarme imaganes tan maravillosas
Welp, I won't look at a sea cucumber the same way ever again.
Einhander49 althought they look like sarlaccs, they just eat plankton... im sure....
Actually the "feather duster worms" at the start of this video are polychaete worms and are very different from the "feather stars" featured in the first part of this series which are a type of Echinoderm. So yes, neither are plants.
That sea cucumber wanted your camera lol
Lol they fold up like cocktail umbrellas!
So beautiful.
I just watched a sea cucumber take a shit. What is life
So, sea cucumbers are basically sarlaccs.
fabulos
Them worms inside the coral look like blackheads that look ready to pop
I need this background music from this video please tell me the name of this music
"Ultramarine" on the Studio Cutz label. Difficult to find now, I think
i want this background music
la video bloque
How very convenient it would be for swimming and diving humans if they could breather through their anuses. There would be no need for all that breathing gear to be strapped onto their backs and no need to have their mouths stuffed with breathing tubes or whatever those bits of apparatus are called. Safer too as they wouldn't drown as long as they didn't sink too far into the depths.
hmmmmmmm the anus is almost the same as the mouth so wut happened if the other sea cucumber enter the wrong way?
