They breed in both temporary ponds and permanent ponds, but appear to favor ponds with long to permanent hydroperiods. In Rhode Island specifically, pickerel frog tadpoles and egg masses were found in permanent manmade rural ponds, farm ponds, and urban ponds surrounded by roads; all of the mentioned habitats were well-vegetated. [12]
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.
They eat flies, crickets, caterpillars, moths, spiders, centipedes, millipedes, earthworms, and snails. [10] The tadpoles' diet is related to its surroundings and food supply. When they are first hatched, they eat plankton. [10] After a few days, they become carnivorous and eat animals. [10] Tadpoles sometimes resort to cannibalism to survive.
This is a list of large carnivores known to prey on humans. The order Carnivora consists of numerous mammal species specialized in eating flesh. This list does not include animal attacks on humans by domesticated species (dogs), or animals held in zoos, aquaria, circuses, private homes or other non-natural settings.
Filial cannibalism is a specific type of size-structured cannibalism in which adults eat their own offspring. [34] Although most often thought of as parents eating live young, filial cannibalism includes parental consumption of stillborn infants and miscarried fetuses as well as infertile and still-incubating eggs.

The relatively large amount of pigmentation in eggs and tadpoles is thought to help expedite development, and tadpoles will congregate in the shallowest, warmest margins of ponds during the day. [ 17 ] [ 7 ] [ 8 ] At nighttime tadpoles settle down into the silty detritus where they are more insulated from the cold nighttime temperatures.
Triops longicaudatus is usually greyish yellow or brown in colour, and differs from many other species by the absence of the second maxilla.Apart from Triops cancriformis, it is the only tadpole shrimp species whose individuals display as many as three reproductive strategies: bisexual, unisexual (parthenogenetic), and hermaphroditic; see below.
