Humpback whales communicate with complex songs that can be as loud as the sound of a jet plane (around 150 decibels).

Illegal fishing accounts for an estimated 11-26 million tons of the annual catch of fish globally.

For every pound of trawled shrimp, up to six pounds of "bycatch” is also captured, including turtles and dolphins.

If not for whaling, ship strikes, pollution and entanglement in fishing gear, some whales could live for over 200 years.
