Bufo melanotictus
Morphology
Bufo melanotictus of often called a toad feature field has it own body from various other
amphibiaris. Of the skin we can see that the nice toad has a more delicate structure and is
always wet. His head is triangular and there are a pair of eyes, lower eyelid and upper eyelid. In
the lower eyelid advanted transparent membrane which can be regarded as a membrane bed
that serves as a tool to keep the eye from the friction when he was in the water. Leg consist of
the upperarm, forearm, falm of the hand and fingers were four of posterior extremity and has
five for exterior extremity. Rear leg consists of the high, calf, poot, radius of five, the membrane
pool that is contained in the form of five, the membfrane pool that is contained in the form of
thin skin between the fingers.

Anatomy
Anatomy
Respiratory system
Respiration is a process of providing oxygen to the body and take carbon dioxide from the
process of metabolism. The system consists of the lungs and skin. This tool has a wet surface (
epithelial layer that contains blood vessel ). Oxygen from the air dissolved in the liquid surface
respiration by diffusion into blood of artery. In this process plays a role in the oxidation of
homolobin will then be taken into the body tissue that need. Toad lung consists of two elastic
pocket that contains folds that form small chambers called alriola, each pocket of the lung
bronchi associated with a short channel, then the two bronchi united.
Digestive system
Toad has digestivus system equipment consist digestive ducts and lymph gland. Digestive tract
starts from the oral cavity, esophagus, stomach , intestines and bowel axis. The length of his
intestines relatively short, it is adjusted to the food is insects. Digestive is composed of hearts
that have a two jowls. There right next to the dorsal jowls gall bladder. Pancreas located
between the curved and yellowish, discharge empties into the cloaca.
Circulatory system
Circulation system in the tool of arteries, capiler, veins, ducts lymphatictus, blood and lymphatic
fluid. Wropped by an oual pericardium membrane consisting of a ventriculum which is adjacent
to the posterior, thick walled muscular and light colored flesh. Has two antrium which is located
next to the anterior and ventriculum and thin walled muscular flesh colored older. And on the
observation there are two left and right of the fayer and one cubicle.
Urinary and reproduction system
Tools main excretion in the frog is a pair of kidney located on the right and left spine. Brownish
red that extends from front to back. The kidney are filtering devices that emit substance that
can dissolve the remaining (mainly urine ) mineral salts and excess water collected from the
body cells and fluid from the blood. Male genitalia in toad testes consists of a pair of yellowish
white. There are sperm and testes spermatozoa through fine channels leading to the kidney and
excreted along of urine through the ureter. Each testes have a coil-ring masca called
seminiferous tubules, which produce a sperm. Sperm are tiny when mature into several small
duseus associated with anterior part of uniferus tubules of the kidney. Sperm then travels
through the tubules and the ureter are united with the canal and temporarily stored
urinogenital posterior who have an enlarged tip that is visicula, while during the united sperm
sprayed through cloaca to fertilized the eggs
Mouth of frog
Mouth bounded by the lower jaw and upper jaw is narrow relationship with pharink associated
with esophagus.the tongue is flat attached to the anterior floor of the mouth but the back-tree
and have a taste bud or in a small papilla on the surface.s
