Though many tadpoles will feed on dead animals if available to them, only a few species of frog have strictly carnivorous tadpoles, an example being the frogs of the family Ceratophryidae, their cannibalistic tadpoles having wide gaping mouths with which they devour other organisms, including other tadpoles.
According to ITIS and WoRMS, this family is classified into 4 genera, although the 4 genera from each database has a little bit difference.The classification from the taxonomy by Bouchet & Rocroi (2005), [3] which is based on classification by Taylor (2003): [7] Taylor classifies Physidae according to the anatomical differences of their penis, the differences among the penial complex, penial ...
Eggs can hatch in under 30 hours and tadpoles can fully develop in one month. [13] They have wide caudal fins and two rows of labial teeth on the top of their mouths and four rows on the bottom. [14] Tadpoles survive on algae and will occasionally eat other tadpoles, [13] and on rare occasions, recently metamorphosed juveniles. [15]
The tadpoles feed on detritus, algae, and bacteria. [34] Tadpoles in more advanced phases of development may show a preference for vegetable matter, but also scavenge or become carnivorous on aquatic life. Captive tadpoles have eaten boiled lettuce and pet food in pellet form. [34] If population density is high, tadpoles have cannibalised one ...
[5] [9] [10] It is also a cannibalistic species—the male African bullfrog is known for occasionally eating the tadpoles he guards, [11] and juveniles also eat tadpoles. [12] An African bullfrog kept at the Pretoria Zoo in South Africa once ate 17 juvenile Rinkhals snakes ( Hemachatus haemachatus ).
When ants bite humans, it grabs the skin and also sprays a compound called formic acid, Frye explains. Ant bites tend to be small, swollen bumps that appear in clusters, Kassouf says.
Most species (e.g. Blyth's river frog L. blythii or the fanged river frog L. macrodon) develop normally, with free-swimming tadpoles that eat food. [5] The tadpoles of the corrugated frog ( L. laticeps ) are free-swimming but endotrophic, meaning they do not eat but live on stored yolk until metamorphosis into frogs. [ 5 ]
They are primarily transmitted by direct human to human contact. But they can be transmitted without touching another human if scabies are on blankets, towels, sheets, and other personal items.
