This is a Turtle-like creature, it can even curl into its shell.
About this creation
The Tarton's average lifespan is around 1000 years. It is a very defensive creature that curls up into its shell whenever it sees an aggressive creature. Its shell is almost impossible to penetrate, it is even harder than diamond.
Although defense is the specialty, I have seen this species attack, usually when provoked. The attack is subtle and slow. It begins with the creature rolling onto its back and spinning in a clockwise fashion. Human subjects are fascinated by this turn of events, and usually come in for a closer look. Once enough speed is generated, Tarton spews shards of fecal matter at its opponent. The feces are so hot that they penetrate the skin with miniscule burns. Once the feces invade the skin, small spores begin to mature into burrowing maggots that consume the flesh, eating the victim alive! What a turn of phrase!
