Animal of the day: Mola mola, otherwise known as an Ocean Sunfish. These fish, as you can tell by the picture, can grow to a great size. They are the heaviest bony fish in the world! And its weight can reach up to 3,500 pounds! Although it has bony ancestors, this fish is made up mostly of cartilaginous tissues, which are much lighter than bone. This is what allows this species to grow as big as it does, allowing its body to reach sizes otherwise impossible for other bony fish.
One of the most captivating creatures I’ve ever seen, this big guy eats mainly jellyfish! They also pose no threat to human divers. They are very docile and calm animals.
