Give one example each of (a) protective colouration (b) structural adaptation in animals for temperature regulation 4.
4. (a) Fish bears a protective colouration. The darker upper part camouflages it against fishermen, while the silvery lower part protects it against predators (bigger sea animals), since looking from below the water blends it with the sky. The different colours in fish are referred to as countershading. Other forms of adaptive colouration are (i) green colours of grasshopper which camouflages it from predators like lizards, birds and mammals (ii) the colour. of lizards (ranging from brown to grey) make it to blend with the soil walls and tree-backs (for wild species) and as such are protected from predators such as snakes (iii) Chameleon possesses photosensitive cells on its skin and is able to change or blend with the colour of any environment in which it finds itself (iv) Bright colours to ward off enemies e.g ladybirds
