Q. Which fish has ’wings’, breathes from behind its eyes and scatters purses in the sea?
Ans.: The rays are flattened cartilaginous fish which are related to sharks. Their fins are joined to the body by large flaps of skin so that they seem to fly through water. They breathe through slits or spiracles which are present behind their eyes. They do not take in the water from which they get oxygen through the mouth like most other fish as they swim close to the bottom of the water. They lay their eggs in hard cases which are commonly known as ‘sea purses’.

Q. Which group of birds do not have feathers on their heads and feet so as to remain clean?
Ans.: Vultures have a well-known ugly look as they do not have feathers on their heads and feet. This has primarily to do with hygiene and their mode of feeding. As they are scavengers feeding on carrion, they would rarely pick up the unclean bits of meat and germs that they otherwise would have on their feathers. This makes them on the whole one of the few species of animals that have adapted for the sake of hygiene.

Q. Which groups of animals have muscles that function without their commanding them to do so?
Ans.: The insects can manage very high wings beat speeds (a mosquito can flap its wings over 500 times a second) because their brain does not give instruction to their muscles to do so. The brain merely switches on the muscles which then continue to beat on their own inbuilt frequency. The speed of the beat is too fast for nerve impulses to normally reach them..
