Shark Dichotomous Key
A dichotomous key is a tool used to identify organisms based on their physical characteristics. It presents a series of paired statements, each with two contrasting options. The user selects the option that best describes the specimen, and the key directs them to the next set of statements.
This process continues until the organism is identified.
Dichotomous keys for sharks typically use characteristics such as body shape, fin shape and position, tooth shape, and presence or absence of certain structures. These keys can be used to identify sharks to the species level.
