Question

Mention any one major similarity and one major difference in the following pairs of animals:
A. Insects and birds.
B. Whales and fishes.
C. Snakes and earthworms.
D. Bat and pigeon.
E. Cuttlefish and dogfish.
F. Wall lizard and frog.

Answer 1

Hint: Some animals, like bats, use echolocation to detect other objects. They emit ultrasonic sounds and then listen to the echoes. Bats can detect similarities in different objects in biology by comparing the time-lapse between emitted sound and the echo. However, this method is not applied to identify similarities between organisms that are very small such as bacteria and viruses.

Complete step by step answer:
Insects have six legs or more and have antennae to locate their prey. Some birds have similar features: their four limbs may be adapted for catching insects in flight or digging up worms on the ground. Other than that though there is no relation between these two classes of animals at all. In biology, there is a hierarchy of life. This means that some organisms are more similar than others. There are two types of classification in this hierarchy: kingdom and phyla. A phylum is a group of organisms that typically have unique characteristics or traits when compared to other groups. When an organism is in the same phylum as another, it would have the same traits even if they were different species or kingdoms. However, for an organism to be in the same kingdom as another, they need not share many similar characteristics. It means that fish are not classified as mammals in the animal kingdom because they do not share any similarities with them within their phylum (animals
).

Pair of animals	Similarity	Difference
(A) Insects and birds	Both have wings.	Invertebrates are birds, while vertebrates are insects.
(B) Whales and fishes	Both are aquatic.	Whales breathe via their lungs, while fish breathe through their gills. Whales are classified as Mammalia, whilst fish is classified as Pisces.
(C) Snakes and earthworms	Both do not have anylimbs.	Snakes are vertebrates, but earthworms are invertebrates.
(D) Bat and pigeon	Both breath throughlungs.	Bats have external ears whereas pigeons have internal ears.
(E) Cuttlefish and dogfish	Both are marine entities.	Cuttlefish is an invertebrate, whereas dogfish is a vertebrate.
(F) Wall lizard and frog	Both are cold-blooded.

Note: While snakes and earthworms seem similar, they are very different creatures. Earthworms are invertebrates with a long tapered body that is usually pinkish-white in colour. They live in moist habitats and can grow up to 8 feet long. Snakes are reptiles that have a long slender body which gives them the ability to move through tunnels or holes in the ground easily.
