Modern classification
Today we classify species
based on shared ________
which is determined by a range

analysis, comparison of bio
-chemical processes, and more.
In Biology, classification is the _______ of species into ______. The Swedish

Let’s put your observational skills to the test - create
your own dichotomous key for these monsters! Doodle
and name your own monster first!
Tip: start by labeling the physical features of each
monster - you will start to notice features that
groups of monsters have and features that are
unique to each monster!
