Grass Frog Dissection

Where is it found?
Grass frogs are found throughout most of North America including Southeastern Virginia, eastern North Carolina, eastern South Carolina, and southern Georgia. The grass frog can be found in meadows, gardens and woodland, and prefer shallow areas of water.
What does it eat?
Frogs tend to prey on insects, worms, snails, and slugs.
How does it breathe?
The grass frog can breathe through its skin.  Because of this, the frog is able to hibernate for months.
Fun fact:
When a male frog successfully attracts a female companion, it will wrap its forelimbs around the female in an embrace.



Liver- secretes bile and processes digested food
Stomach- stores food and begins digestion
Large intestines- stores undigested food
Gallbladder- sac that stores bile made in the liver




Turn the frog on its back and pin down the legs. Cut the hinges of the mouth and open it wide. Use the diagram below to locate and identify the structures inside the mouth. Use a probe to help find each part: the vomerine teeth, the maxillary teeth, theinternal nares, the tongue, the openings to the Eustachian tubes, the esophagus, the pharynx, and the slit-like glottis.
