CLASSES OF VERTEBRATES

8. PISCES
 These are fish.
 These are exclusively aquatic animals.
 Their skin is covered with scales.
 They obtain oxygen dissolved in water
by using gills.
 The body is stream lined, and a
muscular tail is used for movement.
 They are cold blooded
 and their hearts have only two
chambers.
 They lay eggs
 Example – Rohu, flying fish, dog
fish and sea horse fish.

9.  These animals differ from
the fish in the lack of scales.
 They having mucus glands
in the skin.
 Respiration is through either
gills or lungs.
 They have three chambered
heart.
 They lay eggs.
 These animals are found
both in water and on land.
 Examples – Frogs, toads,
salamander and tree frog.

10.  These animals are cold
blooded.
 They have scales, and
breathe through lungs.
 While most of them have a
three chambered heart.
 Crocodiles have four
chambered heart.
 They don’t lay egg in water.
 They lay eggs with tough
coverings and do not need
to lay their eggs in water,

are modified for flight

12. MAMMALIA
 Mammals are warm blooded
animals
 They have four chambered
heart
 They have mammary glands
for the production of milk to
nourish their young
 Their skin has hairs as well as
sweat and oil glands
 Most mammals familiar to us
produce live young once
 However , a few of them , like
the platypus and the echidna
lay eggs , and some like

poorly developed young ones.
 Examples – human, elephant,
cat, camel and dog etc.
