Adults hunt in spring and summer, but only at night or during light rains. Spadefoot tadpoles are dimorphic. Within a cohort, some tadpoles have large mouthparts, while others have much smaller mouthparts. As well as consuming other types of food, large-mouthed individuals are cannibalistic, swallowing other tadpoles whole. [4] [10]
A tadpole or polliwog (also spelled pollywog) is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails.
The adults of this species is primarily fossorial for most of the year, but terrestrial during warm, wet periods. It only enters the water for breeding when nocturnal temperatures are at their yearly maximums and within 2–3 days of rain. [6] The tadpoles hatch from eggs after 2 days and metamorphose within 2 weeks.
Felidae (/ ˈ f ɛ l ɪ d iː /) is the family of mammals in the order Carnivora colloquially referred to as cats. A member of this family is also called a felid (/ ˈ f iː l ɪ d /). The 41 extant Felidae species exhibit the greatest diversity in fur patterns of all terrestrial carnivores. Cats have retractile claws, slender muscular bodies ...
After multiple experiments, Paul Székely, Marian Tudor, and Dan Cogalniceanu concluded that tadpole development is influenced by hydroperiod, or the period in which an area is full of water. [ citation needed ] Since American spadefoot toads breed in shallow waters, they are under "constant stress from drying waters, increasing temperatures ...
Also where the larvae develop into tadpoles and transfer into a terrestrial area. The Houston toad is generally found in areas with loose, sandy soils greater than 40 in (100 cm) in depth and large rolling uplands. Slow-moving or still bodies of water that last at least 30 days are needed for breeding and tadpole development. [16]
The subfamily Felinae includes 12 genera and 34 species, such as the bobcat, caracal, cheetah, cougar, ocelot, and common domestic cat. [ 5 ] Traditionally, five subfamilies have been distinguished within the Felidae based on phenotypical features: the Felinae, the Pantherinae, the Acinonychinae (cheetahs), the extinct Machairodontinae , and ...
Feliformia is a suborder within the order Carnivora consisting of "cat-like" carnivorans, including cats (large and small), hyenas, mongooses, viverrids, and related taxa. Feliformia stands in contrast to the other suborder of Carnivora, Caniformia consisting of "dog-like" carnivorans (includes Canoidea).
