Tyrannophontes theridion

Tyrannophontes theridion is an extinct species of mantis shrimp. Mantis shrimp, members of the order Stomatopoda, are marine crustaceans known for their extraordinary hunting capabilities and complex vision. These shrimp-like creatures are notable for their powerful, specialized appendages used for capturing prey. 

Mantis shrimp have one of the most sophisticated visual systems in the animal kingdom. Their eyes can move independently and are capable of trinocular vision and depth perception. They can see a broad spectrum of light, including ultraviolet and polarized light, which helps them detect prey and predators in various lighting conditions.

These crustaceans are found in tropical and subtropical waters, often inhabiting burrows in the seabed or coral reefs. Despite their small size, ranging from a few centimeters to around 40 centimeters (16 inches), mantis shrimp are formidable predators due to their speed, strength, and sensory capabilities.
