Disadvantages of the Big Headed Turtle

The big-headed turtle is aptly named for its large, triangular head that can measure up to half the width of its shell. Found in the wild from China and Vietnam to Thailand, this aggressive, carnivorous species prefers to reside in rocky mountain streams. Depending on the species of big-headed turtle in questions, adults may measure between 5 inches and 11 inches long. Disadvantages of the big-headed turtle in the wild include its over-sized head, poor swimming ability while disadvantages of big-heads kept in captivity include their climbing skills and aggressiveness as well as health risks like obesity and overheating.

  1. Inability to Withdraw Head into Shell

    • Because the big-headed turtle has an over-sized, triangular head that can be up to half the width of the turtle's shell, the big-headed turtle cannot withdraw its head into its shell for protection. This disadvantage is somewhat alleviated by the fact that the turtle's skull is solid bone covered in horny scale and they only have a thin band of unprotected skin that stretches from its eye to the corner of its mouth.

    Poor Swimming Capabilities

    • Big-headed turtles are poor swimmers. In their natural habitat of fast-moving mountain streams, the big-headed turtle's well-developed ability to cling to rocks, walk and climb are more important. On the other hand, in deeper waters, big-headed turtles with their large head and resulting forward center of gravity ,in combination with their poor swimming ability, can drown.

    Agressiveness and Climbing Skills

    • When keeping big-headed turtles as a pet, their climbing skills can be a disadvantage, as they may be able to climb out of their designated cage or habitat. The top of the enclosure where your big-headed turtle lives should be screened to prevent escapes. Handle big-headed turtles carefully, as when provoked, they are capable of delivering a painful bite with their heavy jaws and hooked beak. Since big-headed turtles are aggressive, they should not be kept with other big-headed turtles in a social environment as they will attack each other and fight.

    Health Risks

    • Big-headed turtles in captivity tend toward obesity. To prevent problems with obesity in big-headed turtles, make sure they have room to exercise in their habitat and feed them less often. Another health risk for big-headed turtles is high temperatures and sun exposure that can cause big-headed turtles to overheat. Make sure turtles are kept in cool habitats with plenty of water and shade where they can protect themselves from the heat.
