What is Biology?

Have you hugged a tree, talked to a plant or dissected a frog today?  

Biology is the study of animal and plant life.  If you're planning to become a veterinarian, a doctor, a horticulturist - then you'll want to study your biology books!

Who lives the longest?

Humans are the longest-lived mammals and giant tortoises are the longest-lived reptiles, sometimes living as long as 150 years. Among birds, the record is held by turkey buzzards at 118 years. But thick-shelled ocean clams called quahogs hold the top longevity record among all animals. These slow-moving mollusks can live more than 200 years.
