Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
The kidneys of snakes are elongated, cylindrical [53] [50] and lobulated. [52] Turtles and some lizards have urinary bladder [50] that opens into the cloaca [54] but snakes and crocodiles do not have it. [50] Compared with the metanephros of birds and mammals, the metanephros of reptiles is simpler in structure. [21]
Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes , anteriorly-attached tongue , limbs folded underneath, and no tail (the tail of tailed frogs is an extension of the male cloaca).
Swim Bladder Disease: Common in fish like goldfish and bettas, swim bladder issues can make it difficult for them to swim properly. Treatment costs are generally minimal, around $50 to $100 for ...
Amniotes have the ability to procreate without water bodies. Because the amnion and the fluid it secretes shields the embryo from environmental fluctuations, amniotes can reproduce on dry land by either laying shelled eggs (reptiles, birds and monotremes ) or nurturing fertilized eggs within the mother ( marsupial and placental mammals ).
Hydric brooding is an egg incubation practice performed by some species of frogs. It involves either placing urine from the bladder on the eggs to keep them wet or holding the body over the eggs to prevent them from drying out. [1] [2] [3] [4]
The amphibian bladder is usually highly distensible; among some land-dwelling species of frogs and salamanders, it may account for 20%–50% of total body weight. [44] Urine flows from the kidneys through the ureters into the bladder and is periodically released from the bladder to the cloaca. [45]
