substance called “spermaceti”, one theory about “spermaceti”
is that the it hardens as a Sperm Whale dives helping
them dive to great depths. As the Sperm Whale begins
to surface the “spermacti” becomes more like liquid
returning the whales buoyancy.
Sperm Whales swim close to each other often touching
and caressing. Sperm Whales communicate using a series

Sperm Whales spend their winter months in warm waters
near the equator where they breed. In the Spring they
