Como los animales aguantan el frio?

We did  a  Experiment  abut how  the  animals  keep  warm  in  the  Artic. We put our hands on 2 different bags  one  had  crisco  the  other  one  did not have anything.there  was  a  container with ice.we used  termometros to know the temperature.The bag that did not have  anything  was colder.The animals like pinguins,whales keep them  selves with their  skin.
