Invertebrates

Phylum 1-Porifera The animals that are in this phylum are sponges. All sponges are filter feeders and the adults are sessile so they attach onto something. Most sponges live in the water and are found pretty much anywhere in the world from freezing cold arctic waters to warm tropical waters. Sponges are multicellular so they are made up of many different cells. Sponges have canal like things running through them where water comes in through pores and is pushed through the canal by the flagellums of many cells until it goes out through another pore.

Phylum 2-Cnideria Cnidera consist of animals like corals, and jellyfish. All cnideria have stingers or nematocysts. Theyre name comes from the greek word cnidos meaning stinging nettles. Cnideria are found in oceans all over the world and some are even found in fresh water lakes and rivers.

Phylum 3- Platyhelminthes Platyhelmenthes are flat worms that are mostly composed of three cell layers. These flat worms have no anus so they discharge waste through the same place where they take in food. Very few fossils have been found of the platyhelminthes.

Phylum 4- Nematoda Nematoda are round worms and there are over 15,000 known species of them. Nematoda can lay up to 200,000 eggs in one day. Nematode comes from the greek word nema meaning thread.

Phylum 5- Annelida Annelida are segmented worms. There are around 9000 known species of annelida.Things like earthworms and leeches are in the annelida phylum. All annelida are bilaterally symmetrical. They have a digestive track and a nervous system.

Phylum 6- Molluska There are atleast 50,000 known species of mollusks. Animals like squids, and snails are mollusks. Mollusks differ in size very much from the giant squid to microscopic mollusks. Most mollusks have soft squishy bodies and have a part called the head and a part called the foot.

Phylum 7- Echinodermata Animals like starfish are echinoderms. Most echinoderms have five fold symmetry or five arms. They also have suction cup like feet things that help them grip onto stuff or pull themselves around. There are roughly 13,000 known species of echinoderms.

Phylum 8- Arthropoda There are over a million known species of arthropoda. Animals like spiders or king crabs are arthropods. Arthropods have exoskeletons and segmented bodies. They live pretty much every where in the world from forrests to oceans.

Questions: Question C- The main difference is that incomplete metamorphisis never pupates or larvaets. Question D- an exoskeleton is a shell like skeleton on the outside of an organism, an organism that filters organisms from water, and an open circulatory system means that there are no veins it just pumps the blood into cavities where cells absoarb it.

Questions: Question A- Invertabrates are animals with no spines. Question B- sexual reproduction is when an organisms eggs are fertilized by another organism, asexual reproduction is when an organism splits apart, budding is when an organism grows a part that breaks off and turns into an organism, and regeneration is when an organism breaks apart and grows that part back.
