REPTILES
•have changeable blood heat (cold-blooded)
•reproduction does not depend on water environment
•adapted to land life•breath by lungs•the surface of a body is protected against
drying by:shell bone
platescorneous
scales
REPTILES•secretion:•concentrate urine (they keep water in the
body)•most of them lay eggs lay eggs • ovoviviparieovoviviparie (young ones are come out from
eggs during laying) – a viviparous lizard, a slow-worm, a smooth snake
• viviparie viviparie – a viper•eggs on the land and some of them care of
them•growth of reptiles is slow, they grow whole
their lives
TORTOISES
•have shells from bone plates, vertebras and ribs grow out of them
• toothless jaws (hard keratin)• live in tropics and subtropics•200 kinds of tortoises•an european pond turtle is original in
our country•A red eared slider, a spur-thighed tortoise,
a galapagos tortoise, a green sea turtle
Crocodiles
•their body is covered by corneous carapaces, there are corneous plates under them
•they live in water (they swim with help of the tail)
•they lay eggs on the land•they eat fish, land vertebrates and
carrions, young ones eat insect and small fish
Squamata
•SNAKES AND LIZARDS•the body is covered by scales•they get the skin off (snakes whole,
lizards in parts )•tongue - jagged •there exist about 6000 different kinds• lizards (eyelids are not grown together)• snakes (eyelids are grown together)
Squamata
•warning behaviour (signals of threat):• they open their mouths •they extend their bodies •they produce sound signals
Squamata
•LIZARDS•the most numerous group of reptiles•most of them live in tropics and subtropics •on ground, in trees, in water•most of them have fully developed legs •their tail breaks off in dangerous
(protection against predators)•there are 3 kinds of lizards and a slow-
worm in our country
Squamata
• SNAKES SNAKES •the youngest group of reptiles•they do not have limbs •both halves of both jaws are flexibly
connected by extensible ligaments swallowing of big bites
•transparent eyelids are grown together •venom glands
Squamata
•their sight is imperfect •they do not have an outer auditory organ
and an ear drum •they have Jacobson´s organ (a hole in
the top plate of the mouth)– it reacts to chemical stimulations (smells)
•they have organs reacting to temporal changes
Squamata
•our snakes:•A viper, ringsnakes (a grass snake, a
smooth snake, an aesculapian snake)•boas :•constrictors, anacondas (South America),
pythons (SE Asia, Australia and Africa)•poisonous:•cobra, rattle-snake, sea serpent
