Fig. 156. Soft-Shelled Turtle (Young) 

 (Trionyx spinifcr) 



These curious creatures make interesting pets, and when small can be kept m 

 close quarters. When alarmed they dig into the sand, but must eventually come 

 out for a breath of air. If the surface is within reaching distance they will do 

 the original "rubberneck" act as above, rather than leave the sand. Soft-shelled 

 turtles are very aquatic and have broadly webbed feet, which enable them to swim 

 rapidly.
