KEY TO ANIMAL GROUPS
• We will use a “key” for animal groups
Why?
A key is a simple to use tool
Versatile, adaptable
Avoid confusion between “look-a-alike” groups
Carry it with you – low tech
Using a key teaches you about the groups (anatomy, life style, habitat, relations)
Provides consistency between users and repeat applications = “standardization” and “quality control”
KEY TO ANIMAL GROUPS
Dos and Don’ts
Do proceed systematically
Don’t jump ahead
Do think about each choice
Don’t make assumptions
Do carefully note specimen characteristics
KEY TO ANIMAL GROUPS
The provided Dichotomous Key is specific for the groups commonly found in the Aquatic Reserves
The Key is for the groups illustrated by the Beach Watcher ID guides The Key is “Artificial” because it does not use embryology,
phylogeny, or relations to other groups The Key uses only those characteristics that can be discerned from
a specimen in hand or on a rock. Let’s walk through some examples Use your keys Ask questions We may not get through all my examples, but you will get the idea.
We’ll Start with an Easy Example – (1)

Review: Who are they? (Picture it in your head and think
about a key feature)
