When hunting, a thresher shark's tail moves so quickly that it lowers the pressure in front of it, causing the water to boil. Small bubbles are released, and collapse again when the water pressure equalizes. This process is called cavitation, and it releases huge amounts of energy stunning the fish.

Bald Eagles (Haliaeetus leucocephalus) fly solo during winter & migration but reconnect with their mates each breeding season. Most eagles pair off by the age of 5 and stay together until one eagle dies. 90% of birds are monogamous but Bald eagles are one of the few that do not cheat on their mates.
