Annelida propaganda!

Phylum Round 3

Annelida: Segmented Worms. This group includes earthworms, leeches, and many classes under the umbrella of “polychaete”. This diverse phylum encompasses deposit feeders (eating dirt), detritivores, scavengers, deadly ambush predators, filter feeders, parasites, herbivores, and more. They are broadly defined by their repeating body segments and parapodia, which are nubby appendages used for both movement and breathing. Some have curved jaws for catching prey or scraping detritus off of rocks, while others have wide, elaborate, brightly colored feather-like fans for filter feeding. While able to crawl freely, a majority of marine Annelids spend most of their time in self-built tubes or burrows. Among their many important functions, they play a key role in mixing soil/sediment, breaking down decaying organic matter, and providing a key food source to countless other animals.

Cnidaria: Jellyfish, anemones, corals, box jellies, and hydroids. They have a gelatinous body with radial symmetry, a decentralized nervous system, and tentacles surrounding a simple mouth. The defining feature of this phylum are their cnidocytes, or stinging cells. There are two different body plans of the Cnidaria; an immobile “polyp” attached to a surface, or a free-living “medusa” which can swim or drift in the water column. Many polyp Cnidarians, such as corals, live in colonies. Some corals build reefs which serve as habitat for other animals. Free-living medusa Cnidarians must return to the seafloor in a polyp-like stage as a part of their life cycle.

Echinodermata propaganda?

Phylum Round 3

Chordata: All animals with a backbone (Vertebrata), but also some invertebrates. Chordata includes fish, birds, mammals, reptiles, and amphibians, but also sea squirts and lancelets. All Chordates have a notochord (supportive rod-like structure), a hollow dorsal nerve cord, pharyngeal slits (for filter feeding/breathing), a post-anal tail, and an endostyle (feeding organ) or thyroid (hormonal gland). Interestingly, many Chordates have overcome the need to raise their young in water by laying shelled eggs or carrying young within the womb. Fur, feathers, and scales are all unique adaptations found within Chordata. This phylum exhibits remarkable diversity overall.

Echinodermata: Sea urchins, sea stars, sea cucumbers, brittle stars, and feather stars. This widespread phylum can be found near every continent, including Antarctica, where they are particularly dominant. They are distinctive for their radially symmetrical body and skeleton located between the outer skin and inner body cavity. They move by hydraulic power using a "water vascular system" which pumps water throughout their body. Hundreds of tube feet extend and retract using this system, allowing them to crawl on the seafloor. These organisms play important roles in the food chain of their habitats, like sea urchins grazing in kelp forests.

Phylum Round 3

Mollusca: Snails, slugs, cephalopods, bivalves, chitons, limpets, and others. This group contains the largest invertebrates, the giant and colossal squids. They are the largest marine phylum, but many members are terrestrial. Although they are incredibly diverse in body shape, all Molluscs generally have a hard “radula” used for eating, a mantle that may secrete a hard shell, and a body mostly composed of dense muscle. These animals can be predators, herbivores, filter feeders, symbiotic, and even parasitic. This phylum exhibits remarkable diversity overall.

Ctenophora: Comb Jellies. The largest animal phylum to swim using hair-like cilia. Their cilia are arranged in rows, called combs or ctenes, down the length of their body. The cilia move in a wave-like pattern that generates colorful reflecting light shows. Almost all Ctenophores are predators of small plankton as they drift in the ocean. They inhabit a variety of marine habitats from the coastal intertidal to the open ocean.

Phylum Round 3

Arthropoda: Insects, arachnids, crustaceans, and others. The largest and one of the most diverse phyla on Earth, Arthropods have thrived on every continent and ocean, including Antarctica. Their most defining feature is their exoskeleton, which provides both support and protection - Arthropods have developed a number of adaptations to overcome the drawbacks of, as my invertebrate zoology professor liked to say, “living in a vacuum-sealed medieval suit of armor”. They possess body segments that have been specialized for their lifestyles, on land or sea. They have relatively complex brains, and many species have shown remarkable cognition. We have had a complicated relationship with Arthropods since the dawn of humanity; they have been critical food sources, disease-carriers and parasites, essential farming partners, and maligned farming pests for thousands of years.

Onychophora: Velvet Worms. This is the only phylum containing exclusively terrestrial members, although their ancestors can be traced back to the Cambrian shallow oceans. Onychophorans are ambush predators, moving with slow smooth steps to creep up on their prey. They have unique mucus glands on either side of their face which can spray jets of sticky slime, which effectively immobilizes their prey. Onychophorans have relatively complex brains, and some even live in social “packs” that live and hunt together. Many species in this phylum are ecologically vulnerable, threatened, or endangered.

I llove tardigrades too and I love seeing this enthusiasm!! Tardigrada propaganda <3

Phylum Round 2

Tardigrada: Water Bears or Moss Piglets. These micro-animals have been found on every continent, including Antarctica. They are well-known for their ability to survive extreme conditions such as dangerous radiation, extreme heat/cold, or lack of food and water. Members of Tardigrada have even been studied on space missions, and survived the vacuum of space. They can endure these conditions by entering a "tun" state, where they lose almost all of their water and slow all their life systems to a near-stop. Tardigrades live on moist mosses and lichens, but can survive when their habitat dries out, and reawaken when water returns.

Ctenophora: Comb Jellies. The largest animal phylum to swim using hair-like cilia. Their cilia are arranged in rows, called combs or ctenes, down the length of their body.

what do you think the chances are that Homo Sapiens win the animal showdown

Honestly, with the tags I've been seeing from Chordata fans, I think some kind of fish is much more likely to win than Homo sapiens! Well. I mean. Technically humans are fish, but. That's a lot to get into
