Deception
Camoflage (crypsis) To be effective – it must be linked with appropriate behaviour (Eg – select background and not move)
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.
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.
Batesian mimicry A good tasting (palatable) animal (the mimic) resembles a bad-tasting (unpalatable) one (the model).
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.
Mullerian mimicry No distinction between model and mimic – several bad tasting species resembling one another. It is easier for predators to avoid them altogether.
Diversion of attack Many butterflies have spots on their wings which look like eyes – this diverts the predator.
Autonomy Shedding of a body part – Eg – all NZ lizards can lose their tails and regenerate them later.
