Animal adaptations behind unusual appearances
These guides begin with the feature people notice, then connect it to anatomy, behaviour and habitat. Similar-looking structures may perform different jobs, while unrelated animals may solve the same problem in different ways.

Noses and faces
A conspicuous nose or bare face can be a sensory organ, air conditioner, feeding tool or social signal. Similar-looking features can perform very different jobs in different animals.

Feeding tools
Feeding structures make sense when the food and habitat are known. A projecting jaw, narrow tongue, suction strike or moving lure solves a particular access problem.

Skin, gills and pressure
Skin can exchange gases, display blood flow, reduce friction or respond to pressure. Soft and folded tissue should be interpreted in the environment where it functions.

Senses and signals
Dark water, tunnels, dense forest and noisy breeding grounds reward information channels that people may overlook. Touch, vibration, resonance and visible skin can all carry useful information.
Open guide
Camouflage and lures
Some predators do not search widely for food. They become difficult to notice, wait and use a small movement or rapid strike only when prey enters range.
Open guide
Digging and burrowing
Digging may create a home, uncover food or provide an escape. Different lineages have modified the structures they already possessed rather than evolving one universal digging body.
Open guide
Flight and movement
A body part that looks oversized often reflects the force it handles. Wings, legs and claws show how movement depends on habitat, speed, body mass and the surface beneath the animal.
