SNAKE-NECKED TURTLE (Chelodina longicollis) : AUSTRALIA 
The serpentine neck 1s too long to be tucked back into the shell. When the animal is 
frightened a portion of the neck is ‘folded sidewa ays along the inner margin of the shell (see 
page 609). Photo by Raymond L. Ditmars. 
LEATHERY TURTLE (Sphargis coriacea) : TROPICAL SEAS 
This sea giant is by far the largest of the turtles. There are records of 1,000-pound 
specimens. It appears to be the survivor of an ancient group of reptiles. Photo by Raymond
