What is fish taxonomy ?
May 7-15 Barcelona
A dichotomous key is a classification tool used to sort, organize and identify a collection of objects or living organisms.
The key is made up of a series of questions with two choices, such as “
Are the scales small or large?”
Each choice leads to another question.
By making choices and progressing logically through the key, users follow a path that ends with the correct identification of the organism.
