Animal Phyla Assessment Study Guide
☻ Know the following chart of the Domain: Eukarya and Kingdom: Animalia.
Phylum
Porifera
Animal Phylum Characteristics
● asymmetrical symmetry
● all live in water floating or attached to one place
Examples
only sponges
● filter feeders (eat other organisms)
● no nervous system
Cnidaria
● radial symmetry
● all live in water floating or attached to one place
● most have tentacles with stinging cells called nematocysts
Mollusca
● bilateral symmetry
● live in fresh water, salt water, or on land
● have soft bodies with a foot
● most have hard shells or shell-like coverings
Annelida
(segmented
worms)
Arthropoda
(means ‘jointed
foot’)
Echinodermata
● bilateral symmetry
● bodies are divided into segments

bodies may have setae (not the leech)
● bilateral symmetry
● have jointed legs
● have exoskeletons -> skeleton on the outside
● radial symmetry
● only live in saltwater
● have spiny or leathery skin
Chordata
● only vertebrate
group
● bilateral symmetry
● have endoskeletons-> skeleton on the inside (backbones)
● paired appendages-> (legs, arms)

Know the following facts:

invertebrate- animals without a backbone
(snails, insects, worms)

vertebrate- animals with a backbone
(cats, birds, snakes, lizards)

bilateral symmetry – the body structures of the animal can be divided into two sides (a
left and a right side) that are alike. Most animals have bilateral symmetry.

radial symmetry – the body structures of the animal equally formed around a central point

asymmetry – no definite shape
