Pied-billed Grebes feed mainly on aquatic invertebrates, and also on small fish and amphibians ( frogs, tadpoles ).

Its diet consists mainly of small fish, but will also eat tadpoles, frogs, and aquatic insects.

They feed on invertebrates, small crustaceans, planktonic animals, daphnia and also frog tadpoles.

These species feed on small aquatic animals such as mollusks, brine shrimp and other crustaceans, larval insects, segmented worms, tadpoles, and small fish.

At the larva stage, tadpoles feed on algae and other organisms in the water.

They feed on aquatic invertebrates such as mayfly larvae and small crayfish, and also on small aquatic vertebrates such as tadpoles and minnows.

The larvae feed on other small invertebrates, including tadpoles.

Aquatic species, such as U. vulgaris ( common bladderwort ), possess bladders that are usually larger and can feed on more substantial prey such as water fleas ( Daphnia ), nematodes and even fish fry, mosquito larvae and young tadpoles.

Aquatic invertebrates that feed on toad tadpoles include dragonfly larvae, diving beetles and water boatmen.

Larval newts usually feed on tadpoles, worms, insects and insect larvae.

Goliath tadpoles are vegetarian and feed on a single aquatic plant, Dicraeia warmingii, found only near waterfalls and rapids, which may help explain their restricted range.

Omnivorous, wood frog tadpoles feed on plant detritus, algae and also attack and eat eggs and larvae of amphibians, including those of wood frogs.

Do not feed the tadpoles celery or salad.

Adults feed predominantly on mosquitoes, gnats and midges ; the larvae feed primarily on other aquatic insect larvae and on tadpoles.

Members of the genus Ranatra, the most widespread and speciose genus, are sometimes called needle bugs or water stick insects as they are more slender than Nepa and feed primarily on invertebrates, but occasionally take small fish or tadpoles.

The tadpoles feed on detritus, algae and bacteria.

When the eggs hatch, he transports the tadpoles on his back, stuck there by a mucous secretion, to a temporary pool where he dips himself into the water and the tadpoles drop off.

When they hatch, the male carries the tadpoles around in brood pouches on his hind legs.

Its eggs are laid on the forest floor and when they hatch, the tadpoles are carried one by one on the back of an adult to a suitable water-filled crevice such as the axil of a leaf or the rosette of a bromeliad.

This classification is based on such morphological features as the number of vertebrae, the structure of the pectoral girdle and the morphology of tadpoles.

The newt tadpoles look initially like small fish fry, but later become more similar to miniature adults, but with " feathery " external gills emerging from behind the head on either side.

While tadpoles control algal populations, adult frogs forage on insects.

Most tadpoles are herbivorous, subsisting on algae and plants.

They take advantage when bodies of water begin to dry up in the summer or early fall and gorge themselves on the resulting high concentrations of fish and tadpoles.

The tadpoles are long when they hatch and live on yolk stored in the cells of the digestive tract for a month.

Wisty was famed for bothering members of the public on park benches on topics including tadpoles, royalty, newts, peace through nudism, inalienable rights, and his friend Spotty Muldoon.

Research is now underway into captive breeding and on which lifecycle stage-eggs, tadpoles or adults-promises the best chance of survival following return to the wild.

A reduction in the number of tadpoles may lead to an overgrowth of algae, resulting in depletion of oxygen in the water when the algae later die and decompose.

As the water builds up, frogs and tadpoles have an abundance of food, such as algae, vegetation, insects, dragonfly nymphs, and other tadpoles.

However, as tadpoles they also tend to eat algae and other small pieces of organic material found in their pools.

Tadpoles survive off of algae and will occasionally turn to cannibalism eating other tadpoles and on rare occasions recently metamorphism juveniles.

After this they start to eat freshwater plankton, and later insect larvae, molluscs and similar food ( unlike frog tadpoles, newts are carnivorous throughout their life ).

This connection was clarified by Smith and Smith ( 1922 ), who showed that saline extracts of fresh bovine pituitary glands could re-activate the atrophied thyroids of hypophysectomised tadpoles.

The female visits the nursery sites regularly and deposits unfertilised eggs in the water which are consumed by the tadpoles.

As the tadpoles mature they develop legs ( front first ), and the growth and use of their lungs is matched by a gradual shrinkage of the gills.

Once cysts are eaten by foraging tadpoles, they excyst ( hatch ) to yield gamonts.

Large quantities of conifer pollen are consumed seasonally by tadpoles.

The physics of tadpoles and the word tadpole was invented by Sidney Coleman.

Lloyd devoted several studies to the possibility, often recounted but never previously accounted for under scientific conditions, that Utricularia can consume larger prey such as young tadpoles and mosquito larvae by catching them by the tail, and ingesting them bit by bit.

Screening is done by use of in vitro test systems ( by examining, for instance, if an agent interacts with the estrogen receptor or the androgen receptor ) and via the use of in animal models, such as development of tadpoles and uterine growth in prepubertal rodents.

They can be distinguished from the tadpoles of other species by the fact that the mouth is the same width as the space between the eyes, and this is twice as large as the distance between the nostrils.

The researchers demonstrated this by genetic analysis and by noting the greater number of physical abnormalities among urban as against rural tadpoles when raised in a controlled environment.

Gowachin are born in a graluz, an indoor pool into which the tadpoles are born and live until their father tests them by swimming through the graz, eating those he can catch.

This may mean that tadpoles have not metamorphosed by late summer when their bogs dry out, and so perish.

It will also take prey and some fruit from vegetation by gleaning and jumping for it or ripping it off in mid-hover, and occasionally dives for fish or tadpoles in shallow water, making it one of the few fishing passerines.

This is believed to provide some protection of the adult frogs and their offspring ( eggs and tadpoles ) from predation by fish and other predators of permanent water bodies.

The bullfrog explains that he did not do it, as he and his wife were busy trying to save their tadpoles, who were eaten by a large fish.

The monophyly of Centrolenidae is supported by morphological and behavioral characters including: ( 1 ) presence of a dilated process on the medial side of the third metacarpal ( an apparently unique synapomorphy ); ( 2 ) ventral origin of the musculus flexor teres digiti III relative to the musculus transversi metacarpi I ; ( 3 ) terminal phalanges T-shaped ; ( 4 ) exotroph, lotic, burrower / fossorial tadpoles with a vermiform body and dorsal C-shaped eyes, that live buried within leaf packs in still or flowing water systems ; ( 5 ) eggs clutches deposited outside of water on vegetation or rocks above still or flowing water systems.

When hatched the tadpoles are recognizable by their skinny tails in relation to the size of their bodies.
