The quokka (/ ˈ k w ɒ k ə /) (Setonix brachyurus) [4] is a small macropod about the size of a domestic cat. It is the only member of the genus Setonix. Like other marsupials in the macropod family (such as kangaroos and wallabies), the quokka is herbivorous and mainly nocturnal. [5] The quokka's range is a small area of southwestern Australia.
They can propel their vomit up to 10 feet (3.0 m). [4] The European roller, a much smaller bird found in parts of Africa, Europe, Asia, and the Middle East, uses vomit in a different way. A baby European roller will vomit a foul-smelling orange liquid onto itself to turn away a predator.
Quokkapox virus (QPV), also known as quokka poxvirus, marsupial papillomavirus, or marsupialpox virus, [1] is a dsDNA virus that causes quokkapox. It is unclear whether this virus is its own species or a member of another species. [2] It primarily infects the quokka, which is one of only four macropodid marsupials to get pox lesions.
The much lower frequency of attacks between nesting seasons suggests such behavior may have evolved due to its benefit for the mobber's young. Niko Tinbergen argued that the mobbing was a source of confusion to gull chick predators, distracting them from searching for prey. [10]
One baby tardigrade had the confidence to hitch a ride on the back of one of its greatest predators — a microscopic worm called a nematode — in a video that won fifth place and $600 in Nikon's ...
Laying eggs late prevents the chicks from being tossed out of the nest, but it can have a negative impact on the offspring's survival. [ 3 ] [ 2 ] Late egg-laying causes later hatching, which increases the probability of death, since these late chicks will be smaller than their nestmates, putting them at risk.
Anti-predator adaptation in action: the kitefin shark (a–c) and the Atlantic wreckfish (d–f) attempt to prey on hagfishes. First, the predators approach their potential prey. Predators bite or try to swallow the hagfishes, but the hagfishes have already projected jets of slime (arrows) into the predators' mouths.
When did Predators catfish hockey tradition start? 1999 or 2002, depending on who you ask. Bob Wolf , a former Broadway bar owner and musician, says he threw the first catfish on the ice during ...
