However, in contexts where " amoeboid " is defined more loosely, there are many amoeboid species that are in the Excavata clade.

Amphibians typically have a larval stage that lives in water but there are many different behavioural adaptations that have developed among species to bypass this necessity.

The two large families are cosmopolitan, with many of their species found in the northern hemisphere, and the smaller families are usually confined to Australia and the adjacent areas, or sometimes South America.

( Which of the two families is actually larger is unclear, owing to uncertainty about exactly how many species exist in each family ).

Flowers across the Apiaceae are fairly uniform and are usually perfect ( hermaphroditic ) and actinomorphic, but some are andromonoecious, polygamomonoecious, or even dioecious ( as in Acronema ), with a distinct calyx and corolla, but the calyx if often highly reduced, to the point of being undetectable in many species, while the corolla can be white, yellow, pink or purple.

The thick inner layer of the shell is composed of nacre or mother-of-pearl, which in many species is highly iridescent, giving rise to a range of strong and changeable colors, which make the shells attractive to humans as decorative objects, and as a source of colorful mother-of-pearl.

Amaranth species are cultivated and consumed as a leaf vegetable in many parts of the world.

Antibacterials such as penicillin and erythromycin, which used to have high efficacy against many bacterial species and strains, have become less effective, because of increased resistance of many bacterial strains.

As with many other game species, the best sources of historical and large scale population data are hunting bag records and questionnaires.

Due to decreasing availability and rising prices of premium-quality traditional tonewoods, many manufacturers have begun experimenting with alternative species of woods or more commonly available variations on the standard species.

This is because many species are unable to regulate their internal body temperature.

The importance of hybridization in creating new species of animals is unclear, although cases have been seen in many types of animals, with the gray tree frog being a particularly well-studied example.

Frogs are also fairly numerous, especially the green tree frog, Litoria caerulea, but there are many others.

One of many frog murals throughout the city.

In many birds, the esophagus is largely a mere gravity chute, and in such events as a seagull swallowing a fish or a stork swallowing a frog, swallowing consists largely of the bird lifting its head with its beak pointing up and guiding the prey with tongue and jaws so that the prey slides inside and down.

The importance of hybridization in creating new species of animals is unclear, although cases have been seen in many types of animals, with the gray tree frog being a particularly well-studied example.

Their scarcity outside of anuran hosts had led many to speculate that the others are just incidental infestations — maybe the infested snake had just eaten an infested frog, for example.

Sometimes, too, intra-species recognition is fallible: in many species of frog, the males are not uncommonly seen copulating with females of the wrong species or even with inanimate objects.

The many ways to search for a frog: linguistic typology & the expression of motion events.

This number can be expanded to as many as four ( juvenile dirt-dragons as larva, " adult " graboids as pupa, Shriekers as subimago, and Ass-blasters as imago ) or reduced to as few as two ( Dirt-Dragons as larva and Ass-blasters as adults ; similar to the sharp lexical division of amphibian metamorphosis into tadpole and frog / newt ).

The presence or development of the vocal sac is one way of externally determining the sex of a frog in many species.

He also designed a round-edged frog mounted to the butt by means of a recessed track, which he encouraged his bowmakers to use ; other details of craft, however, make it possible to identify the actual maker of many Vuillaume bows.
