Extant animals size

[Catherine]

Those are all interesting animals. The blue whale is always impressive. We just can't take in how large it really is.

The real star is the Greenland Shark. They have an incredible life span and the species has been around a long time.
A lot of history has passed by as these sharks live and grow. The shark is older than my country. 

I still find it hard to believe that there are clams and sponges and other sea creatures that live that long. Life on land must be harder. Life spans are definitely shorter.
