Try Not To Stare At The Mouth Of A Basking Shark
The basking shark is the second-largest fish in the ocean, after the whale shark, and it happens to be one of the gentlest creatures. The giant, gaping mouth may make some beg to differ.

Basking sharks measure around 40-feet long and spend most of their time near the surface of the ocean with their mouths open. This species of shark is a filter feeder, which means they prefer to eat planktonic prey. According to Oceana, they filter up to four million pounds of water every hour while they feed.
