Wolverines are observed finding large bones invisible in deep snow and are specialists at scavenging bones specifically to cache.

By targeting the USAG-1 gene, researchers believe that they can help people without a full set of teeth regrow teeth. The team says that humans have a third set of teeth available as buds, ready ...
This is due to its punctuality of migration during mating season as it moves from warm to cold waters. Atlantic mackerel can swim at a sustained speed of 0.98 m/sec with a burst speed of 5.5 m/sec, [123] [124] while chub mackerel can swim at a sustained speed of 0.92 m/sec with a burst speed of 2.25 m/sec.
