Porifera (Sponges)- Morphology, Classification, & Evolution- Invertebrate Paleontology | GEO GIRL

Ғылым және технология

Porifera is a phylum of invertebrate animals which includes sponges. In this video, I go over Porifera anatomy, structure, morphology, spicule types, complexity (ascon, sycon, leucon), classification (classes- glass sponges, calcareous sponges, demosponges, stromatoporoids, archaeocyathids), reproduction, ecology, & reef evolution. Sponges have a lot of body parts, all of which I label and discuss in this video. I also discuss the distinction between common sponge spicule morphology which helps when determining the spong species in a particular fossil. I also go over the 3 major groups of sponge morphology, ascon, sycon, and leucon sponges. Ascon sponges are most simple, while leucon sponges are most morphological complex. I then go over each of the classes of sponges and the time range they lived in throughout Earth's history, then we move to sponge reproduction, which can occur either sexually or asexually. Sponges can also regenerate complete animals from broken fragments of a sponge, which is useful after strong storms. I then go through the entire evolutionary history of sponges through the Paleozoic and Mesozoic Eras. I close out the video by discussing the mysterious history of archeaocyathids and avenues for future research that may help us finally determine which phylum archeaochyathids should belong to. Hope you enjoy! ;)

    Suddenly I understand what dream-Gary said to SpongeBob in SpongeBob’s dream when he said “Beware of your wandering eye you little *poriferan!* ” I always thought he was saying some word synonymous with ‘scoundrel’ or something, when he was actually referring to SpongeBob’s taxonomic classification 😂

    First and foremost: Thank you SO much for your content! It really saves me in my studies! However a minor nitpick: I think you got one thing wrong even on the second try: I believe it is SclerospongIAE not SclerospongEA, but as I said, a REALLY tiny nitpick! 😅Also, according to my knowledge, I believe they are considered to be contained within Demospongiae as well.

    Kind of like how multicellularity led to sex and death, and how sponges can reproduce from parts of themselves, and we can't because we've gotten too big . . . Natural Selection and genetics is something that comes at a certain stage/level. Before then was self-organization of stable non-equilibrium structures from a previous state of equilibrium structures like rocks?

    Such a happy approach to learning! Question, in areas where corals are dying due to rising sea temperatures are other reef builders such as sponges affected too?

    Yes, they are also affected by the acidifcation that is caused by the CO2 & temp. increase, but they are not as directly affected by the temperature increase alone because they don't have the symbiotic algae that the corals have. :)

    I was happy to stumble on your site because I think it's the best I've seen! You finally helped me identify some or many of the many marine fossils I find daily in the desert southwest where I live and where they are incredibly well preserved. Since I am a lay person, sort of a citizen scientist. I have some extremely unusual, possibly glass sponge fossils the likes of which I have never seen on any paleontological site. May I send you photos? if anyone could identify them it would be you. I have taken them to a rock shop co-owned by the guy who discovered a new fossil dinosaur named Sonorasauris (or something like that) and to a so called expert at Tucson Gem and Mineral Show, and no one knew what they were. My curiosity skilling me!
