And welcome to Frantz Biology and Genetics! Yes that is a “real frog” but it has been dead for at least a year. The frogs come from a biological supply house, they were raised for scientific investigation in highschools across the nation. The frogs are preserved in a solution of alcohol with a small percentage of formaldehyde. These two students have chosen to wear surgical gloves which can protect the hands from drying, but are otherwise not necessary.
