The real life kracken, these spineless beasts can reach lengths of over 40 ft, hunting who knows what down in the darkest depths of the sea. Their cousin, the Colossal Squid, is the heaviest marine invertebrate.
The widest fish in the sea, these majestic flapflaps can have a wingspan of over 20 ft! They live a long time, and studies show that they can recognize themselves in a mirror, which is some high level thinking for a fish.
The mola mola is the most awkward fish in the sea. My soul critter. The world's heaviest bony fish, these chonks can weigh almost 5000 lbs and grow up to 14 ft tall!
The largest of the seven species of sea turtles, these sleek squirtles are the most wide-ranging reptile in the world.
Male elephant seals can tip the scales at over 8000 lbs, and only come ashore to mate and molt. Northern elephant seals were hunted to near extinction, down to only a dozen or so individuals, but have since recovered to impressive numbers!
The blue whale is arguably the largest animal to ever have lived. Their aorta is big enough for a person to swim through, and their flukes are as wide as an airplane's wings, and they can communicate across ocean basins.
The largest fish in the sea by length, and the sexiest if sexiness is measured in spots. Whale sharks are gentle giants, roaming tropical waters and slurping up small fish and crustaceans. I couldn't pick between the three biggest fish, so I made one of each.
