Animal Basics and Evolution
All animals share this trait: Hint - they are made of more than one cell.
Multicellular organisms
The main purpose of classification is to do this.
To make organisms easier to study
This type of symmetry has two even halves.
Bilateral Symmetry
This type of skeleton is found inside vertebrates.
Endoskeleton
This phylum includes insects, spiders, and crabs.
Arthropod
Animals that must eat other organisms for energy are called this.
Heterotrophs
This tool uses yes-or-no questions to identify organisms.
Dichotomous Key
Jellyfish have this type of symmetry.
Radial Symmetry
Insects and crabs are protected by this hard outer covering.
Exoskeleton
Snails, clams, squid, and octopus belong to this group.
Mollusk
About 95% of animals on Earth belong to this group.
Invertebrates
This is the science of naming and classifying organisms.
Taxonomy
Sponges usually show this type of symmetry.
Asymmetrical Symmetry
Worms use this fluid-filled skeleton for support.
Hydroskeleton
Jellyfish and corals belong to this phylum
Cnidarian
Squid and octopus lost this structure to improve speed and flexibility.
Shells
Which is the largest taxonomic group: species, class, phylum, or kingdom.
Kingdom
Earthworms, insects, and humans share this type of symmetry.
Bilateral Symmetry
This skeleton is found on the outside of the body.
Exoskeleton
Segmented worms belong to this class
Annelid
Metamorphosis can be classified into these two types.
Complete and incomplete metamorphosis
This scientist created taxonomy, the system of organizing living things
Carl Linnaeus
This symmetry type is common in sea stars and sea anemones.
Radial Symmetry
Name one type of skeleton found in invertebrates and explain why it is useful.
