Today’s interesting fact has to do with Blue Whales.

Blue Whales are as far as we know the largest animals to ever have ever existed.

The Blue Whale is a filter feeder using baleen, a hair-like substance that grows from the roof of the mouth, to filter out small fish, krill and plankton from water they engulf, but do not swallow.

All whales that have baleen have a special joint at their chin that allows each side of the jaw to rotate.

This allows them to engulf vast amounts of water.

The Blue Whale has a mouth cavity that can engulf a volume of water equivalent to its own body mass.

Today’s interesting fact has to do with Krill.

Krill are small shrimp like invertebrates that are found in all the oceans of the world and they feed many large animals, such as whales and basking sharks as well as many smaller species.

It is estimated that if you took all the Antarctic krill and placed them on one side of a balancing scale and put all the humans on the planet on the other side of the scale, the Krill would weigh more.
