What consists of the phylum porifera?

Porifera is the phylum of spongers, or pore-bearers. Water flows in many pores, and out. Choanocytes trap the bacteria unto the sponge. SPICULES are had skeletal pieces. Look for POROUS surface and very visible LARGE openings.

What consists of phylum Cnidaria and its different classes?

Phylum Cnidaria includes jellyfish, corals, sea anemones, and animals like Hydra. Their defining feature is cnidocytes, specialized stinging cells often found on the tentacles. A nematocyst is a tiny capsule inside one of these cells that shoots out a thread to catch prey or defend the animal.

Anthozoa: Polyp only. Sea anemones and stony corals live as polyps.

Scyphozoa: Medusa is the main form. Most also have a small polyp stage. (A broad, flattened bell with frilly feeding arms near the center.)

Hydrozoa: Many have both polyp and medusa forms. Hydra has only the polyp form. (With a cluster of tentacles around the mouth at one end. (thread-like))

What differentiates Nematoda from Platyhelminthes?

Platyhelminthes are shaped like a leaf, Nematodas are shaped like a strand of spaguetti. Platyhelminthes are flat from top to bottom, while Nematodas tend to curl at the end.

What differentiates between Class Errantia and Class Sedentarian?

Errantia: A row of bristly lobes on both sides, like little paddles. The fleshy lobes are parapodia, and the bristles sticking out of them are setae.

Sedentaria: Body rings and a wide, smooth band called the clitellum. Its bristles are small and easy to miss. A flattened body with fine rings and a sucker at each end. The suckers are especially helpful if the rings are hard to see.

Polyclaphora (chitons): Eight overlapping shell plates like armor.

Gastropoda (snails, SLUGS): A snail or conch typically has one coiled shell.

Bivalvia (clams, oysters): Two shell halves joined by a hinge.

Cephalopoda (octopuses, squids): Look for a cluster of arms around the mouth, near the large eyes.

What differentiates the phylum anthropoda from chelicerata, crustacea, hexapoda, and myrapoda?

Arthropods: Segmented body, jointed appendages, and exoskeleton

Chelicerata: No antennae. Horseshoe crabs, spiders, ticks, mites, scorpions, BARNACLES. 4 pairs of walking legs (typically)

Myriapoda: 1 pair of antannea. Many legs along a segmented truck.

Hexapoda: 1 pair in the insects shown. Insects typically.

Crustacea: 2 pairs of antennae. Crayfish, lobster, shrimp.

Class: Holuthuroidea

What differentiates all the classes from echinodermata?

Echinodermata: It has a water vascular system. Tiny tube feet. Endoskeletons

Asteroidea: Broad arms that blend into the center. (Sea stars)

Ophiuroidea: Thin flexible arms that begin abruptly at a distinct central disk. (Brittle stars, Basket stars)

Echinoidea: A rigid internal skeleton called a test. (Sea urchins, sand dollars)

Holothuroidea: A long, thick, leathery body. (Sea cucumbers)

What constitutes phylum Chordata and all its subphylums?

Phylum Chordata: Dorsal hollow nerve cord (a hollow tube of nervous tissue along the back, in vertebrates it develops into the brain and spinal cord), Notochord (a flexible rod that supports the body UNDER the nerve cord), Pharyngeal slits (Openings in the throat region), Post-anal tail

Subphylum Urochordata: A sea squirt loses the notochord as it gets older, keeps the pharyngeal slits for filter feeding. (Look for siphons sticking out)

Subphylum Cephalochordata: Keeps all four traits, including the notochord. Siphons have a slender pointed body. Lancelet.

Subphylum Vertebrata: A backbone develops around the notochord. (Frogs, fish, cats, humans, birds belong here)
