6. Cold-blooded Animals
• They take on the temperature of their
surroundings
• They are hot when their environment is
hot and cold when their environment is
cold
• In hot environments can have blood
that is much warmer than warm-blooded
animals
7. • In warm environment more active
• In cold environment sluggish and lazy
– This is because their muscle activity
depends on chemical reactions which run
quickly when it is hot and slowly when it is
cold. Period of inactivity is called
aestivation (hibernation)
8. Warm-blooded Animals
• Try to keep the inside of their bodies at a
constant temperature.
– In a cooler environment by generating their
own heat
– In a hotter environment by cooling
themselves when they are hot.
• To generate heat, warm-blooded animals
convert the food that they eat into energy.
9. Types of Food-eating Animals
• Carnivorous Animals that eat other
animals
• Herbivorous only eat vegetables
• Omnivorous eat both meat and plants
10. Vertebrates
Vertebrates are further divided into five main
groups:
– Pisces Fish
– Amphibia Amphibians
– Reptilia Reptiles
– Aves Birds
– Mammalia Mammals
11. Pisces
• They are aquatic and live in
different habitats
– Fresh water, Salt water, Ocean,
Rivers
– Except Dead Sea
• Fish are cold-blooded
• Skin Scales
• Means of locomotion fins
12. • Respiration Through gills
– Exception: Lung-fish, and snake-head fish
have two respiratory systems
Lung Fish
Snakehead
Fish
13. • Eating habit
– Carnivorous Angler fish, Shark, Wolf
fish, Catfish, Snakehead
– Herbivorous Trout, Goldfish, Scat,
Pacu, Clown fish
– Omnivorous Panda corydoras,
Swordfish, Piranha
20. • Live both on land and water
Amphibians
• Cold-blooded
• Egg-lying
– Immature life in water Gills
– Adults live on land Lungs and
absorption through skin
• Slimy skin absorb moisture and
oxygen through skin
– Without moist conditions, their skin
dries out and they die.
21. • Habitat
– Mostly often found near ponds,
marshlands, swamps, and other areas
where freshwater is available
• Locomotive organs
– Young ones tail
– Adult Legs
• Examples
– Frog, Toad, Salamander, Axolotl, Blind olm
26. • Cold-blooded
Reptiles
• Skin Dry, Tough and Scaly
– As a reptile grows, it sheds its outer
layer of skin.
• Tetrapods two sets of paired
limbs
• Sprawling posture the upper
legs join the body at the sides.
27. • Respiration Lungs
• Hearing organs
– Lack outer ears
– Inner ear respond to vibrations
• Capable of regeneration
– Lizard
• Longevity
– Tortoise and turtles live up to 150 years
– Crocodiles can live up to 100 years
36. • Adapted for flight
Aves
– Exception: Hen, Penguin, Peacock, Ostrich,
Kiwi, Emu, Turkey, The Falkland Flightless
Duck, Rheas, Cassowaries, Flightless
Comorants, Snoring Rail, Campbell Island
Teal, The Kakapo Parrot
• Warm-blooded
• Egg-lying
• Skin Have feathers
– Prevents loss of body heat
– Helps in flight
– Exception: Penguin
37. • Hollow bones
– Provide passage for air from lungs, which supply it
direct to all parts of body
• Locomotive organs
– Wings, exception Penguins
– Legs
– Toes Adapted for particular purposes
• Hearing organ
– Lack outer ear
– Inner ear
38. • Mouth Beak (Adapted for particular
purposes)
• Neck Flexible
– For wide vision
– Aid feeding
– Helps in sleeping
• Sense of sight Most important organ
• Habitat Land, Air, Water
• Migration Annual and seasonal.
