Показать описание
These 9 phyla contain roughly 90 percent of all animals found on Earth. Phylum Porifera
Sponges are pretty basic animals with no specialized organs but they are filter feeders that suck up plankton and other organic matter found in the water

Phylum Annelida
This phylum is made up of Segmented Worms which include earthworms and leeches. This is a large phylum, with over 22,000 species including ragworms, earthworms, and leeches. In addition to having segments, these worms contain a digestive system, most have a closed circulatory system and a nervous system.

Phylum Nematoda – The Roundworms These worms inhabit some bizarre places. Inside your intestines, the hearts of dogs, or inside wasps. Nematodes are very small, slender worms: Many are parasites but others are free-living

Phylum Platyhelminthes – The Flatworms are ribbon-shaped worms that can absorb food and oxygen through their skin by diffusion.: Examples include planaria, and tapeworms Many are parasites and some like the planarian can regenerate a copy of themselves if it is cut in half.

Molluscs (Mollusca)
This phylum includes snails, clams, slugs, squid, and their relatives. Mollusks are the largest marine phylum, comprising about 23% of all the named marine organisms molluscs have a mantle with a significant cavity used for breathing the presence of a radula which is similar to a tongue and a nervous system.

Arthropods (Arthropoda)
The largest animal phylum, This phylum includes crustaceans, insects, arachnids, and other organisms. Arthropods have an exoskeleton, segmented bodies, and jointed appendages

Echinoderms (Echinodermata)
Include Sea stars, sea urchins, and sea cucumbers Echinoderms have radial symmetry and are found on the sea bed at every ocean depth Echinoderms contain a water vascular system that helps with gas exchange, feeding, sensory reception, and locomotion

Cnidaria
Cnidarians are famous for their stinging cells. This phylum contains
Jellyfish, and sea anemones They mostly have two basic body forms: swimming medusae and polyps, both of which are radially symmetrical

All of the previous phyla contain animals that are invertebrates which means they do not have a backbone
Chordates include animals that have a notochord most people call this the backbone and a spinal cord
The phylum includes
All types of fish,
amphibians,

reptiles,

birds,

Chordates includes a bit more than just vertebrates, it also includes tunicates, which includes sea squirts, salps and larvaceans. And the other being the cephalochordates, which today only just includes the lancelets, all others are extinct.

Phylum porifera
- Porifera means porus surface
- Pores are of 2 types
- Osteal small and many
- Osculer– large and few
- Body has two layered surface
- Outer layer ->pinecoderm
- Inner layer->choenoderm
- Pinacoderm has pinacocytes
- Choanoderm has choanocytes which are
flagellated
- Water canal system
- Asexual= Budding, Binary fission & Gemmule
formation
- Sexual ->Amoebide cells
- Produces sperm and ovum
- Skelton is spicules or spongine
- mycospongida without skeleton

The phylum is not "echnoderm" it's echinoderm. Echino = spiny, derm = skin, like the sea urchin.
