If an animal bites you while in the lab or in the field, INFORM your teacher immediately! Remember that to handle animals is a privilege. Treat all live animals and preserved specimens that you encounter or handle with respect.
(In the Virtual Laboratory, there is no danger of being bitten, but you should always treat animals with respect, regardless of whether they are alive, preserved, or virtual!)
