How do scientists classify organisms?
• Group first into:– Kingdoms (the largest)– Phylum– Class– Order– Family – Genus (first part of scientific name) – Species (second part of scientific
name)
• Use binomial nomenclature (two-parted names) to identify species
How many species of animals do you think there are?

Some of the phyla… of 36• Phylum Porifera (“pore bearing”) – sponges• Phylum Platyhelminthes (“flatworm”)• Phylum Annelida (“ringed) - worms• Phylum Cnidaria (“possessing stings”) – corals, sea
anemones, jellyfish • Phylum Arthropoda (“jointed legs”) – insects and
crustaceans• Phylum Mollusca (“soft bodied”) – snail, squid, octopus,
clam• Phylum Echinodermata (“hedgehog skin”) - sea urchin, sea
cucumber, sea star• Phylum Chordata (chord = string)

lizards• Class Amphibia (amphi = on both sides,
double; bios = life) - frogs• Class Aves (avi = a bird) • Class Mammalia (mamma, mammil = milk fed)
