Discussion Strong swimmers, softshells cruise submerged, breathing through snorkel-like snouts. They like to bask near the shore, but are easily disturbed, and display great agility and speed in retreating to the safety of the water. Extreme care should be taken in handling softshells. The long neck and sharp jaws have surprised many a careless person.
