Feeding the Christmas Tree Worms!!

[pierrevanderweerd]

Wizard merboy! So that tail... I actually did it twice, as I didn't like how it turned out the first time. Anyway, this is (loosely) based on a "Christmas Tree Worm." Cool creatures that I didn't know even existed until a couple of days ago!

I moved the Christmas Tree Worms on top of the rocks and the Porites are already looking better! That’s the first time I’ve seen polyp extension in months!

The porites are regaining their green glow!

You can see the green Christmas Tree Worm, in the front, moving its lophophores (the colored tentacles that make the “tree”).

#MarineLife Post 5th edition by indahs.com #scuba It was named after its looks that resemble Christmas tree. Christmas Tree worm (spirobranchus giganteus) is a tube-building worm that lives in the stony coral. They have beautiful crowns that shaped like Christmas tree with bright color feather tentacles (radioles).  These worms are regularly seen in tropical sea water like in the Caribbean and Indo-Pacific. They are very sensitive to movement and lights and react very fast by retracting their radioles inside their tubes. The tube of the worm is lined with appendages that aid the worm in mobility. The worm does not move outside its tube and the appendages do not help the worm to swim. I have never seen the worm outside of the coral, so I have no clue about its appendages appearance. The worm itself is very small with average length of 3.8 cm.  But it is easy to spot because of its colorful radioles. Its radioles colors are varied from red, purple, yellow and blue. The radioles help the worm in filtering the water particles and plankton for food. The female and male reproduce by releasing sperm and eggs into the water. I think I managed to capture the moment on my first image. I hope y'all have a wonderful holidays! 💙 🐳🐙🐬💙 #saveourseas #christmastreeworm #christmastree #uwphoto #paditv #padi #instadive #marinebiologyshots #scubadive #sealife #marinelife #uwpic #marinebiodiversity #instagood #xmas pics by #indahs_photography https://www.instagram.com/p/BrxKmHvla_K/?utm_source=ig_tumblr_share&igshid=1femb59v8p8ku
