Deception

Camoflage (crypsis) To be effective – it must be linked with appropriate behaviour (Eg – select background and not move)
3
Camoflage (crypsis) To be effective – it must be linked with appropriate behaviour (Eg – select background and not move) Eg – Eggs and chicks of ground-nesting birds rely on this to avoid detection. https://www.youtube.com/watch?v=pgDE2DOICuc https://www.youtube.com/watch?v=pgDE2DOICuc

Counter shading Open water fish (kahawai) have silver undersides and dark on top – this makes them less visible against the light background when seen from below and the darkness below when seen from above.
5
Batesian mimicry A good tasting (palatable) animal (the mimic) resembles a bad-tasting (unpalatable) one (the model).
6
Batesian mimicry A good tasting (palatable) animal (the mimic) resembles a bad-tasting (unpalatable) one (the model). This gives the mimic protection as the predator associates the colouration with the gross taste.

Batesian mimicry A good tasting (palatable) animal (the mimic) resembles a bad-tasting (unpalatable) one (the model). This gives the mimic protection as the predator associates the colouration with the gross taste. Eg – Monarch butterfly is distasteful and the viceroy mimics it’s colouration.

Mullerian mimicry No distinction between model and mimic – several bad tasting species resembling one another.
9
Mullerian mimicry No distinction between model and mimic – several bad tasting species resembling one another. It is easier for predators to avoid them altogether.
10
Diversion of attack Many butterflies have spots on their wings which look like eyes – this diverts the predator.
11
Autonomy Shedding of a body part – Eg – all NZ lizards can lose their tails and regenerate them later. https://www.youtube.com/watch?v=B2JdRPKYyTc https://www.youtube.com/watch?v=B2JdRPKYyTc
