Red-Eared Slider Turtles 

What do turtles use to communicate?

A shellphone!

Interesting Fact: During brumation, T. s. elegans can survive anaerobically for weeks, producing ATP from glycolysis. The turtle’s metabolic rate drops dramatically, with heart rate and cardiac output dropping by 80% to minimise energy requirements.^[25][26] The lactic acid produced is buffered by minerals in the shell, preventing acidosis.^[27] Red-eared sliders kept captive indoors should not brumate.
