These unique turtles draw fold their necks side-ways into the shell rather than drawing them straight in, as do the related Asian and Australian species. However, they lack the outlandishly-long necks typical of their Australasian cousins. Most are highly-aquatic (entirely so in the case of the bizarre Mata Mata) and make interesting long-lived pets. Delicate and larger species such as the critically-endangered Red-Headed Side-Necked Turtle and the 60+ pound Giant Amazon River Turtle, are best left to the care of specialists with space (and money!) to spare.
