The sloth bear is not as specialized as polar bears and the panda, has lost several front teeth usually seen in bears, and developed a long, suctioning tongue to feed on the ants, termites, and other burrowing insects
To make up for this short amount of time, the queens produce many workers per generation. [1] The initial brood is a clutch of around twenty larvae that emerge in about ten days. [ 1 ] Arctic bumblebee larvae grow fast, and will experience a near tropical environment due to the heat production of their queen, and later on, of the workers.
Projected change in polar bear habitat from 2001–2010 to 2041–2050.
