Despite their enormous size, whale sharks are actually a harmless filter-feeding species of shark. About the size of a school bus with a mouth that’s a meter wide, whale sharks eat by straining small organisms like plankton, schooling fish, and squid from the water. While whale sharks are the biggest fish in the sea, they're actually threatened by the tiniest plastic particles — micro- and nanoplastics. #4ocean 📸: @jesshaddenphoto
