American cockroaches (Periplaneta americana) lie inactive in lab container after being chilled in refrigerator in a demonstration to show their cold-blooded nature. Insects are cold-blooded which means their body temperatures change with the temperature of their surroundings. These cockroaches are not harmed in any way and will become active once they warm up. | |
