Animals that are _______________________________________are asymmetrical.
Animals that are _________________________________ are symmetrical.
Animal has radial symmetry if it can be_____________________________________,
through a central axis, into equal halves.
 Animal has bilateral symmetry if it can be _____________________________________
into similar right and left halves forming mirror images of each other.
Not all animals have a skeleton  but some have:
 Exoskeletons: hard, ________________________________________________________ protecting internal
organs, providing framework for support, and places for muscle attachment.
 Endoskeletons: support _______________________________________________protecting some organs and a
bracing for muscles to pull against.

Kingdom Animalia
Multicellular
Heterotrophs (consumers)
Lack cell walls

Body Plans : Symmetry



Animals that are irregular in shape are asymmetrical.
Animals that are regular in shape are symmetrical. Animal has radial symmetry if it can be divided along any
plane, through a central axis, into equal halves.
Animal has bilateral symmetry if it can be divided down its length into similar right and left halves forming
mirror images of each other.
Invertebrates
8 main phyla
1: Phylum Porifera: Sponges
 simplest form of animal life
 live in water
 Do not move around
No backbones
95% of all animals are on this group
