Frog dissection
Frog dissection is one of those labs that almost everyone does at some point in the middle or high school years. The step-by-step dissection below features a grass frog that has been double-injected so the arteries and veins are much easier to see and identify.
Before You Dissect
Before you start to dissect, you always want to make observations about how the specimen looks.

Skin
The frog's skin is colored and spotted to help camouflage it. This coloring can change and is controlled by pigment cells in the skin called chromatophores. At the base of the frog's back, locate the cloaca, which is the opening from which waste, eggs, and sperm are discharged.
Hind Legs
Notice the frog's hind legs, and specifically, the large muscle that's used for jumping. Frogs can jump more than 20 times their own length - so they need those powerful muscles.

Digits
Take note of the frog's digits (toes and fingers). You'll see the hind legs have five digits and webbing. The webbing helps frogs be efficient swimmers.

However, the front legs have four digits and no webbing.
