The animal taxa include Porifera, Ctenophora, Placozoa, Cnidaria, Xenacoelomorpha, Chordata, Ambulacraria (including phylum Echinodermata), Scalidophora, Panarthropoda, Nematoda, Rotifera, Chaetognatha, Platyhelminthes, Mollusca, and Annelida.
| The goal of the associated exercise is to gain an appreciation of the diversity of animal phyla, with emphasis on invertebrate animals. These include the sponges, the comb jellies, the placozoans, the jellyfish and relatives, members of phylum Xenacoelomorpha, the chordates as includes the vertebrates, starfish and their relatives, the arthropods and relatives (e.g., insects, spiders, shrimp, lobsters, etc.), the roundworms, the rotifers, members of phylum Chaetognatha (a kind of worm), the flatworms, the mollusks, and the segmented worms such as the earthworm. |
The above video is my take on the Universal Tree of Life, with brief focus here on kingdom Animalia.
The above video takes a very brief and very broad look at the diversityin body plans associated with kingdom Animalia. Note the distinction made between Parazoans, which basically are the sponges, and Eumetazoans, which are all other animals. Also, among the Eumetazoans are the Radiata versus Bilateria.
Though the above video is billed as considering especially the 'simple' animals, really not all of the animals covered, e.g., particularly the mollusks, are necessarily all that simple… Considered (in some cases very briefly) are members of phylum Porifera, phylum Cnidaria, phylum Platyhelminthes, phylum Rotifera, and the already mentioned phylum Mollusca. Note, though, that this statement is for sure incorrect, "Platyhelminthes have their mouth and buttholes on opposite ends of their bodies… ", as in fact for flatworms (i.e., members of phylum Platyhelminthes) the mouth and the anus are the same opening. In any case, this is the first of three Crash Course videos that together cover a diversity of animal types, almost all of which among that diversity which are invertebrates.
The above video is billed as considering especially the 'complex' animals. Considered are members of phylum Annelida and phylum Arthropoda, both of which invertebratephyla that display segmentation.
The above video is a fun compilation with an emphasis on invertebrate animals, but is more a series of ecological stories than much of a summary of anatomical or life historycharacteristics. Really, the goal is one of attempting to convince the viewer that invertebrate animals are ecologically important, or at least something to think about.
The above video is a "biggest" list, in this case of invertebrate animals.
The above video provides an overview of the chordates, only a few of which are invertebrates.
