A salp mothership flies through the cosmos of Davey Jone’s locker off San Diego, CA. -
Salps are barrel-shaped, planktonic tunicates. They may look like jelly fish but in fact tunicates are more closely related to humans than jellies. At a young age they even have notochord (similar to a spine) which makes them a chordate, like us. But, the notochord is only present during the larval stage and as an adult it is essentially brainless, making it an ideal candidate for congress. They move by contraction, that pumps water through their gelatinous body. As water is pumped through their body they are propelled (one of the most efficient propulsions in the animal kingdom) and they also filter water through their feeding filters, collecting food. Individuals in an ideal environment can grow 10% of their body length per hour.
During this form or part of their life cycle they will reproduce asexually by producing and releasing chains of tens to hundreds of individuals. -
These small chains are known as blastozooids and continue to grow. They can reach several meters in length. Now they can reproduce sexually (a bit more fun) with their sequential hermaphroditic neighbor (a bit more strange) and release individual salps like explained earlier. -
So why have an alternating life forms? Well, it seems it is good for business. With both life forms in abundance when they meet plankton blooms they are ready to grow like gangbusters.
Aug. 20, 2017: While everyone is looking up today and contemplating spacey things, we should also remember to look down to find other worldly creatures. Here is a pelagic drifter. A Salp chain, (Pegea sp.) 42 ft below the surface while free diving with @sdexpeditions 9 miles off the coast of San Diego, California.
I'm now on my way to the offices of Talpa Productions in order to (hopefully) get cast in a TV show that let's people talk about their passion in front of an audience. The audience then scores the talk and the best talk wins. This is not my favorite thing in the world to do, but I'll do pretty much everything to share my love for freediving! Fingers crossed!!!🤞
Royalty is in da house! 😀
Will Goodman, #worldrecord holder on the #JJCCR to a #depth of 290m, the 2 only female #techinstructors in Southeast Asia @yvonnepress and @theresia_gollner and @c_jolyane who just completed her TDI #Decompression Procedures course. And a very big thumbs up goes to @hiro_ccr_diver and @samuel._.mason who finished an amazing 10 days of #techdiving around the #giliislands with a 110m #trimix#rebreather#dive . We were also lucky enough to see a #hammerheadshark 2 days in a row...happy days #diving and keep up the amazing work.
And thanks Alfie for making us look good on the pictures. ☺
Yesterday was a great day for underwater visibility......the surge was really strong though, came in and out....so one second you are in a lake....another you are getting sucked into a sea cave....and another you are spearing head first into a 600 pound male sea lion. Oh ocean....you always keep me on the tips of my fins. #WHPadeventure
