Ecology

Dragon turtles inhabit deep coastal waters, oceanic trenches, and the great rivers leading to them. They are apex predators, devouring whales, sharks, krakens (rarely), and the occasional ship. They migrate annually across thousands of leagues following warm currents and breeding grounds. Their shells host entire ecosystems: coral, anemones, parasitic crustaceans, and sometimes shipwrecks half-grown into the carapace. Sailors who recognize the patterns of these encrusted shells learn to recognize specific dragon turtles by name, paying tributes accordingly to specific elder turtles whose territories overlap shipping lanes.

Behaviour

Dragon turtles are territorial but not aggressive without cause. They demand tribute from passing ships, calculated by the season and cargo, and accept payment with ceremonial dignity. Refusal triggers immediate retaliation. They speak Draconic and Aquan, though they prefer silence, communicating through ripple-patterns on the water and tail-strikes on the seafloor that travel for miles. They mate rarely but devotedly, raising young alongside long-lived merfolk and sahuagin tribes who serve as honor guards in exchange for protection.

Origin

Sages debate whether dragon turtles are true dragons, marine reptiles convergent toward draconic form, or hybrids of an extinct primordial lineage. The dragon turtles themselves consider this question impertinent and refuse to discuss it. Their lairs occasionally contain artifacts predating any known civilization, suggesting they remember oceans now drowned beneath continents long since uplifted, and continents now drowned beneath oceans long since formed. They are old in ways that resist easy taxonomy.
