The Wonder of Deep Sea Echinoderms
Рет қаралды 554,712
Күн бұрынEchinoderms come in countless shapes and sizes, but there are a few unique features that unite the 6,500 living species. Many adults of this phylum have 5-way radial symmetry; a pattern most prominent in the shape of the starfish. In addition, they have skeletons made up of interlocking calcium carbonate plates and spines called ossicles. This provides rigidity for their complex structures, making up the protective shell of urchins, or the column-like spine of crinoids. These skeletons are also the reason why fossils for echinoderms are so widespread and well-preserved, with some crinoid fossils being as old as 500 million years. Perhaps the most peculiar creatures of this phylum are the holothurians. Sea cucumbers, with their retractable feeding tentacles and tube feet around the mouth which they use to forage in the sea floor mud.

@@lazyrshmuk I must say. Bitcoin price action has fluctuated over the past few days and weeks, with bulls and bears reaching a clear deadlock, the aggregate cryptocurrency market has been following Btcoin's lead and is struggling to gain decisive momentum. An analyst is now pointing out that BTC has been holding above a key macro level for the past few months. He believes that the recent consolidation above this level bodes well for his near-term outlook and could indicate that a significant improvement is imminent in the weeks and months ahead. Tips like this explain why it is recommended that investors and newbies trade with the help of professional traders like Nicholas Steven.

Aww thank you, that’s really nice to hear. I used to have this crappy ipod from the dawn of time - but the one upside was it was so old that KZfaq would keep on playing even with the screen off, so I’d listen to nature documentaries and clips from Attenborough shows on KZfaq while I slept. Hearing that my vids are now being used in that way is amazing 😁😁

🧠👍 I think the fastest way to reduce greenhouse gas effect is for whales to increase in population since when they eat krill in the night and excrete waste they release nitrite compounds and ammonia which enrich the krill population and those krill reproduce and increase their number repeating the cycle, trees that absorb 22kg of co² per year but a whale can store it in their bodies, 510kg of that per year but whales only reproduce after three years.

Wait I got that wrong here: In death, whales carry the tons of carbon stored in their massive bodies down to rest on the seafloor, where it can remain for centuries. Whale excrement fertilizes the ocean, producing large phytoplankton blooms that absorb enormous amounts of carbon dioxide. Thx cetaceans👍

Your videos are one of those places. Even when, sometimes, they end on a kind of sad note like this one. Because although life on the oceans is deteriorating more and more, there's got to be something I can help with. So, thank you for that, Leo.

Oooh hell yeah, echinoderms are the best!! That was a great video as usual :D The part on brittle stars was especially cool, those are my favourite echinoderms. You might find it cool that at the chalk fossil site I work at, over 30 different fossil brittle star species have been found. This diversity rivals that of brittle stars in the Mediterranean! Also about the 5-way radial symmetry - there are sometimes genetic defects, where these echinoderms have instead a 4-way or a 6-way radial symmetry! By the way, I've been really busy up until now, but I can't wait to catch up on your Marianas Trench video. :) Hope your end of year exams went well, too!

Thanks so much Christian!! I have a couple of echinoderm fossils, and what astounds me is both the detail of them, and how close they resemble extant species today. Got any nuggets of info on their evolutionary history? If do let me know - hope you’ve been doing okay!
@christianv-h3278 2 жыл бұрын
@@NaturalWorldFacts Yeah I've been doing well, just working to get a paper on crocodiles published. :) You're absolutely right, echinoderms have gone through loads of changes, but many body plans you see today appeared millions of years ago. The great thing about echinoderms is that their skeleton is made of easily-preservable calcium carbonate, which means they fossilise _really_ well. Thanks to this, we can record a long, 500-million-year old evolutionary history. The orders we see today (brittle stars, sea urchins etc) don't represent all the echinoderm groups, some of them have gone extinct (for instance during a mass extinction event roughly 250 million years ago). Some of these disappeared orders include "mitrates", an enigmatic group of echinoderms that are thought to have crawled on the seafloor using their tail-like appendage. Mitrates are known for instance from some truly spectacular fossils from Germany: www.fossilmuseum.net/Fossil_Sites/Bundenbach/Rhenocystis-latipedunculata/Rhenocystis.htm A tidbit of info closer to what I study, the chalk cliffs in Denmark I study have such abundant echinoderms that they represent roughly half of the entire fauna...
