Lemurs, lizards, whales — all are famed for their tails in some way. But which animal has the longest tail of all?
In proportion to their bodies, grass lizards have the longest tails of any known living animal. The tails of these small, lightweight lizards are two to three times the length of their torsos, Tommy Owens, a manager in the department of birds and ectotherms (cold-blooded animals) at the Dallas Zoo, told Live Science. For instance, long-tailed grass lizards (Takydromus sexlineatus), a member of this family, can grow up to 1 foot (30 centimeters) long, but their bodies are only 2 to 3 inches (5 to 8 cm) long — the rest is all tail.
