FROG (RANA TIGRINA)
→ Kingdom : Animalia, Phylum : chordata, Sub-Phylum : Vertebrata, Superclass :
Tetrapoda, class : Amphibia
• Dual life, Poikilothermal (cold blooded), Winter sleep (Hibernation) Summer sleep
(Aestivation), Camouflage & Mimicry.
* Morphology
→ Eyes bulged (Covered with nictitating membrane)
→ Tympanum Copening of ear)
→ Body is divided into head & trunk (tail & neck absent).
→ Smooth & slippery body due to presence of mucus.
→ Dorsal side (Olive green), Ventral side (pale yellow)
→ Fore limb- 4 digit & hind- limb -5 digit)
→ Male having copulatory pad (1st digit of forelimbs)
→ Male having vocal sac.
* Digestive System
Start from mouth & stop cloaca.
→ Adult frog (Carnivores) (Short Alimentary canal), Tadpole (herbivoras)
→ Mouth → Buccal cavity → pharynx → Oesophagus → Stomach
Rectum ← L. Intestine ← S. Intestine
→ Biloped tongue, teeth only tryst in upper jaw.
→ Major digestion completes in Small intestine → villi & microvilli (Increases S.
area)
* Respiratory System
→ Skin (cutaneous respiration) (30%)
→ Lungs (pulmonary respiration) (65%).
→ Buccal cavity (Buccopharyngeal) (5%).
→ Frog : positive pressure breathing (Humans → -ve press breathing)
* Circulatory System
→ 3chambered heart, Incomplete double circulation.
→ Closed circulatory system
→ Heart (Myogenic) (blw lungs on ventral side of Thoracic region)
→ Dorsal view shape ventral view
• Sinus venosus (Triangular)
• Conus Arteriosus (Sac like) RBCS
Biconvex,
→ deoxygenated blood Ko right
