Did You Know Tuesday

Did you know that the largest mammal on planet Earth is the blue whale? These majestic sea creatures can grow as long as 110 feet in length and can weigh upwards of 200 tons! It’s heart is also the largest of any animal, weighing nearly 1,300 pounds in an adult.

The blue whale was put on the endangered species list in 1966 after years and years of the whaling industry hunting them to near extinction. The species has rebounded thanks to these protections.

The diet of a blue whale consists of small, marine creatures called krill, which they strain from the ocean water using natural sieves in their mouths. An adult blue whale will consume nearly 40 million krill in one day.
