Dragon turtle

Dragon turtles are aquatic creatures that are related to dragons. While they cannot fly, they are adept swimmers and many consider them to be the most powerful non-dragons, and one of the most dangerous things in the ocean, after Krakens. Many sailors avoid the territories of dragon turtles or attempt to placate the creatures with treasure.

Dragon turtles appear to be huge sea turtles with long tails used to attain great swimming speeds. Their bodies are protected with a heavy shell which makes it impervious to most weapons. Dragon turtles are capable of expelling a blast of scalding steam from their mouths. An adult dragon turtle can measure from 20 to 30 feet from snout to tail, with a shell from 15 to 25 feet in diameter, and can weigh 8,000 to 32,000 pounds.

The shell's actual color is about the same color as the sea around it. Its limbs and neck are a lighter color, highlighted with golden fringes. Adult dragon turtles can surpass 40' (12.2m) in length.
