Study Notes

Animal Classification Overview

Animals are multi-celled eukaryotic heterotrophs that lack cell walls.
They demonstrate diverse structures and functions, categorized into various phyla and classes.

Phylum Platyhelminthes

Characterized by bilateral symmetry and a mouth, but no anus.
Commonly includes flatworms, many of which are parasitic.

Phylum Cnidaria

Known for stinging cells and radial symmetry.
Includes jellyfish and corals, with a mouth but no anus.

Phylum Mollusca

Soft-bodied organisms with shells and bilateral symmetry.
Have both a mouth and an anus; an example is the snail.

Phylum Annelida

Segmented worms that exhibit visible blood vessels and bilateral symmetry.
Possess both a mouth and an anus.

Phylum Arthropoda

Features jointed legs and bilateral symmetry.
Includes organisms like insects and spiders, with a mouth and anus.

Phylum Echinodermata

Comprises sea stars and sea urchins; exhibits radial symmetry.
Characterized by a digestive tract, gills, and open circulation (not part of the syllabus).

Phylum Porifera

Organisms that are multicellular and without symmetry.
Known as sponges, they are filter feeders and often attach to rocks.

Phylum Chordata - Class Mammalia

Organisms that have a mouth and anus, bilateral symmetry, and fur.
Warm-blooded and nurture their young with milk.

Phylum Chordata - Class Aves

Possess feathers, cold-blooded scaly legs, and exhibit bilateral symmetry.
Have a mouth and anus, and are warm-blooded.

Phylum Chordata - Class Amphibia

Features moist skin, bilateral symmetry, and a mouth and anus.
Cold-blooded, they lay eggs in water.

Phylum Chordata - Class Reptilia

Show scales, cold-blooded nature, and can lay eggs on land.
Have a mouth and anus and bilateral symmetry.

Phylum Chordata - Class Pisces

Fish with scales and a mouth and anus.
Cold-blooded and lay eggs in water.

Phylum Chordata

All members have bilateral symmetry and a mouth and anus.
Distinguished by possessing a notochord, which serves as a primitive backbone during development.
