Cnidaria and identify parts
|
Includes hydras, anemones, corals, and jellyfishes. the basic body plan of a cnidarian is a sac with a central gastrovascular cavity, which function as both a mouth and an anus. there are two main life stages: a sessile polyp, which is cylndrical with tentacles; and a mobile medusa form.

Lophotrochozoans
|
has a wide range of body forms. they are named for the lophophore structure which is a ciliated crown used for feeding. Trochophores, named for a distinctive life stage shared by many of its members.

|
Platyhelminthyes and identify
|
Part of the Lophotrochozoans clade, have bodies that are flattened and lack a true body cavity. species include ones that live in marine, freshwater, and moist terrestrial enviroments. (parastic species such as tapeworms and flukes

Mollusca and identify
|
Part of the lophotrochozoans clade, include chitons, snails,slugs,oysters,scallops,clams,octopuses, squids, and nautluses. Bodies have three main parts: a muscular "foot", used for movement, a visceral mass containing most of the internal organs, a mantle (which is a fold of tissue that drapes over the visceral mass and sometimes secretes a shell.

Arthropoda
|
largest group of organisms on the earth, with more than one million described species most of which are insects. Common characteristics of arthropods include segmented bodies, a hard exoskeleton, and jointed appendages. The four members of arthropods are Chelicerates, Myriapoda, Hexapoda, and crustacea.
|
|
|
chelicerates and identify
|
Examples- spiders,horseshoe crabs, ticks, mites
this group is named for its clawlike feeding appendages called chelcerae, which serve as pincers or fangs. Cephalothorax is known as the fused head and thorax |
|
|
Myriapoda and identify
|
Examples- millipedes and centipedes
this group has a pair of antennae and three pairs of appendages modified as mouthparts, including the jawlike mandibles. Myriapods are known for their long bodies and having many pairs of legs |
|
|
Hexapoda
|
Identify (insects and relatives) They have six legs, consolidated thorax with three pairs of legs, where most arthropods have more than 3 pairs of legs.
|
|
|
Crustacea and identify
|
Examples-pillbugs, wood lice, crayfish, crabs, lobsters, shrimps. THey have a biramous (two-parted) limbs, appendages on their abdomen and two pairs of antennae.
