In part 2 of our name 5 things series, we make slightly more progress in finding possible animal opponents that a human might be able to take on in a fight, assuming the opponent is human-sized. As noted in part 1, the question is fraught with complexity. You have to fight the organism in its own habitat, but you may be allowed time to put on boots. Despite these constraints, we do come up with a short list of candidates. Without basking too much in this achievement, we then move on to consider which animal might win the battle royale of human-sized animals. Here again, there is some unexpected complexity to unpack, including the context-specific nature of fighting ability depending on one's opponent. We consider the importance of keeping your mouth closed, exploiting your hooves, protecting your neck, and discounting your horns. If you have any suggestions for contestants we have ignored, send us an email (maskedman@limitedappeal.net). Theme music courtesy of General Patton vs. The X-Ecutioners and Ipecac Recordings.

Welcome to Episode 91! Today we'll introduce the Deuterostome animals, and explore the taxonomy and phylogenetic relationships within the most basal extant branch; the Echinoderms.

Kirk gives us all deja vu with a story about an accidental discovery in Antarctica, Rachel talks hearts for Valentine's Day and Victoria talks about female sexual selection and interesting experiments to prove it exists. 

https://www.armatusoceanic.com/podcast/013-submarine-special   Thom thought he had the podcast to himself, but it turns out the professor is back after 88 days at sea. It's time for our submarine, or human occupied vehicle (HOV) if you're posh, special. First we reunite ‘Vegemite and Haggis' and talk to submarine pilot Tim Macdonald about his and Alan's undersea adventures around Australia. Manganese nodule fields, gothic cathedrals, and an undersea UFO. Life starts to imitate art. We chat with sci-fi author John Quentin who Alan has been consulting with while he writes his next book: The Galathea Legacy, about deep-ocean plastic pollution taking place at the site of the Galathea Expedition trawls in the Philippine Trench. A site which Alan and Tim recently dived… forcing John to tweak the draft as he strives for realism. We then speak with Patrick Lahey and Frank Lombardo of Triton Submarines, a bespoke submarine manufacturer, about privately owned submersibles. Initially as luxury pleasure craft but we soon find out that there is a wide range of reasons why someone would want their own sub. Throughout their careers they have had many incredible experiences, like seeing a sixgill shark give birth and communicating with bioluminescent organisms. The podcast wouldn't be complete without checking in with Don Walsh. He tells us about the large commercial tourist submarines which have now produced more tourist submariners than the US navy. It's a packed episode but we sneak some news in there too. Deep-sea fishes have more variation in body shape than shallow-water fishes. A new species, genus, and family of brittle star from a lineage dating back to the Jurassic. Coelacanth can live up to a century and Mesobot, a new method for studying open water animals.   Glossary Autonomous vehicle: A vehicle that doesn't need a human pilot Brittle star: Related to sea stars, they have very flexible whip-like arms. Echinoderms of the class Ophiuroidea Globular: Globe-like, spherical Human Occupied Vehicle (HOV): Another term for a submarine Hypoxic: Insufficient oxygen Thrusters: the propellers on an underwater vehicle that allow it to move   Links Deep-sea fish have a lot more body shape variation than shallow fish Deep-sea fish are confused by complex structures New family of brittle star Coelacanth can live to a century John's upcoming book The Galathea Legacy Triton submersibles Atlantis tourist subs   The hidden track is real, Thom did say ‘anus' on TV. You can see us and a lot of our guests, and experience the Five Deeps Expedition, in Expedition Deep Ocean on Discovery+

#050: Two massive oil refineries owned by Marathon Petroleum and Royal Dutch Shell operate on the Puget Sound, where tankers containing millions of gallons of crude oil ply the waters. What happens when an Exxon Valdez-style catastrophe occurs? An oil spill would devastate the cornucopia of wildlife that thrives in and around the Sound: Mollusks, Crustaceans, Echinoderms, Cnidarians ... Cetaceans and other vertebrates. Tribal fisheries and other industries of the ocean would be wiped out for generations.

This week's episode is all about echinoderms, or at least the star-shaped echinoderms! Thanks to Llewelly for the suggestion about feather stars and crinoids! A very pretty starfish: Crown of thorns starfish. Do not touch: Pumpkin starfish or orange throw pillow? YOU DECIDE: Sea daisies. Not much to look at tbh: A banded arm brittle star: Ruby brittle stars: Brittle stars riding around in a jelly: A basket star: Basket stars got TEETH THINGS: A stemmed crinoid: A lovely feather star: Further reading: Echinoblog, a really amazing resource and so much fun to browse Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we’re going to look at some marine animals that most people barely think about, but which are really interesting. It was going to just be about starfish and maybe one other animal, but while I was still researching starfish, listener Llewelly suggested I cover feather stars and crinoids. They’re related to starfish, so I thought I’d tack them on. And if you talk about starfish, you really have to talk about brittle stars too, and if you talk about brittle stars you have to talk about basket stars. Basically, I had to stop myself from breaking this episode into two big episodes about echinoderms. It’s just the stars this time. Before we get into echinoderms, though, a quick note about my schedule. Next week I’m going on a trip to Paris, France! I know it sounds like I’m rich and just travel as my whim takes me, but actually I just have really generous relatives. A week and a half after I return from Paris, I’ll be in Atlanta, Georgia for DragonCon, where I’ll be on a panel about podcasting. In other words, I won’t be around much on social media for the rest of August, but don’t worry, I’ll have episodes recorded and scheduled to run normally while I’m gone. Okay, now let’s get into echinoderms. Echinoderms include sand dollars, sea urchins, starfish, and many others, and every single echinoderm lives in the ocean. Many of them can regenerate limbs and other body parts, and instead of blood they have a water vascular system. In most echinoderms, seawater enters the body through slits or pores, then travels through canals within the body to transport oxygen to cells and waste products out of cells. Echinoderms have internal skeletons made of calcium carbonate, but they’re invertebrates because they don’t have a backbone. Heck, technically they don’t even have a back. Echinoderms show radial symmetry, which means their bodies are roughly the same in all directions instead of having a clear front and rear. The echinoderms we’re talking about this week are ones that also exhibit pentaradial symmetry, which means they have five sides. And the best-known echinoderms out there are starfish. There are about 1,500 species of starfish known, and some of them are really weird and some are only kind of weird. Most have five arms but some have a whole lot more. Starfish are members of the class Asteroidea, which just delights me. A better name for them is sea star, since they’re not fish at all. Starfish have been around for at least 450 million years, but in 2012 paleontologists found a fossil of the oldest known ancestor of starfish in the mountains of Morocco. It’s about 515 million years old, from the Cambrian period. It was only about an inch and a half long, or 4 cm, and looked similar to the modern-day sea lily, or crinoid. If you recall, the Cambrian period was when life was expanding rapidly in the oceans and evolving sometimes quite strange body plans. You know, like things with FIVE LEGS. Most starfish have ossicles in their skin, little hard beads of calcium carbonate that help protect the animal. In some starfish, the ossicles are more like spines or even spikes. Although cartoons of starfish usually make them look like their legs are always exactly star-shaped,

This episode was a blast to produce for a vertebrate scientist. I learned a ton about the echinoderms, the group of invertebrate animals to which sea stars, brittle stars, sea cucumbers, sea urchins, and crinoids belong. Be prepared for more adventures with invertebrate animals in the future. Engineering Echinoderms with Elizabeth Clark! This episode would […] The post Episode 23: Meet the Echinoderms! Adventures with Ancient Sea Stars! appeared first on Past Time Paleo.

Echinoderms are characterised by a mineralised skeleton, specialised water vascular system and five-fold symmetry. It is this unusual body plane symmetry that gives the starfish its star-shape. None of these features, however, are possessed by the closest living relatives of echinoderms – the hemichordates. Palaeontology offers a unique perspective into the early evolution of echinoderms, revealing that echinoderm characteristics were acquired in a step-wise fashion from a bilaterally symmetrical ancestor. We speak to Dr Imran Rahman, a postdoctoral researcher at the University of Bristol, about the early evolution of echinoderms, from worms to stars.

Dr. David Pawson talks about what it is like to be on a dive in one of the deep-sea submersibles. In the 1980s Pawson was a member of a team of four scientists who made more than 150 submersible dives off Florida and in the Caribbean, to study the echinoderms. They discovered about 200 species of these beautiful animals, about thirty percent of which were new to science. The team has published many papers describing these animals and their lifestyles, and they continue to conduct laboratory studies of the specimens they videotaped, photographed, and collected. Perhaps the most astonishing dive was made near Nassau in the Bahamas, where the team found about fifty automobiles piled up on the seafloor! These old cars had been transported offshore on a barge and then pushed into the ocean; they inadvertently created an effective artificial reef, and they were covered in animals—sponges, deep-sea corals, sea whips, and more. More recently, Pawson has been conducting research on deep-sea sea cucumbers from the northern Pacific and the western Atlantic. Dr. David Pawson is an expert on echinoderms—sea cucumbers, sea urchins, and sea stars.
