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

Nine million tons of plastic ends up in the ocean every year, killing one million seabirds and 100,000 marine animals.

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

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