Dissecting a frog is a common and important experience in introductory biology or anatomy. Although you may feel intimidated at the thought of dissecting an animal, you can have a profound learning experience if you know how to do it correctly.
Dissecting a frog is not easy if your those people who afraid to get it but for me it's very easy to catch a frog, since I already encountered this during laboratory experiments since when I was high students during college years and until now.
