THE ANIMAL FILES

Common snapping turtle

Chelydra serpentina

A long neck changes the view from the mud.

The common snapping turtle can remain partly concealed in shallow mud while its long neck brings the snout to air. It also uses both plant and animal foods.[1]

Breathing from cover

A snapping turtle can rest beneath mud with little more than its head exposed. Its long neck reaches towards the surface, and the nostrils at the tip of the snout allow an occasional breath.[1]

An omnivore's opportunities

The menu includes aquatic plants, carrion, invertebrates and various vertebrates. Ambush hunting and scavenging are both part of the picture.[1]

Behaviour in context

When disturbed in water, these turtles often slip away or shelter in nearby mud and vegetation. This is a contextual observation, not a guarantee about every encounter.[1]

A COMMON MIX-UP

Does the name mean it constantly attacks other animals?

No. Its diet and behaviour are varied; observations in water often involve avoidance rather than confrontation.[1]

TRY A LITTLE REASONING

Why is a long neck useful to a turtle resting in shallow mud?

Reveal the explanation

It can bring the snout-tip nostrils to air while much of the body stays covered. The useful feature is the combination of neck length, nostril position and shallow water.[1]
