Cranes are tall wading birds in the family Gruidae. Cranes are found on every continent except for South America and Antarctica and inhabit a variety of open habitats, although most species prefer to live near water. [1] They are large birds with long necks and legs, a tapering form, and long secondary feathers on the wing that project over the ...
Hydra (/ ˈ h aɪ d r ə / HY-drə) is a genus of small freshwater hydrozoans of the phylum Cnidaria.They are native to the temperate and tropical regions. [2] [3] The genus was named by Linnaeus in 1758 after the Hydra, which was the many-headed beast of myth defeated by Heracles, as when the animal has a part severed, it will regenerate much like the mythical hydra's heads.
The common crane (Grus grus), also known as the Eurasian crane, is a bird of the family Gruidae, the cranes.A medium-sized species, it is the only crane commonly found in Europe besides the demoiselle crane (Grus virgo) and the Siberian crane (Leucogeranus leucogeranus) that only are regular in the far eastern part of the continent.
Of the four crane genera, Balearica (two species) is restricted to Africa, and Leucogeranus (one species) is restricted to Asia; the other two genera, Grus (including Anthropoides and Bugeranus) and Antigone, are both widespread. [5] [1] Many species of cranes are dependent on wetlands and grasslands, and most species nest in shallow wetlands.
The whooping crane (Grus americana) is an endangered crane species, native to North America, [3] [1] named for its "whooping" calls. Along with the sandhill crane ( Antigone canadensis ), it is one of only two crane species native to North America, and it is also the tallest North American bird species. [ 3 ]
Austroplatypus incompertus is a species of ambrosia beetle native to Australia, and is the first beetle (order Coleoptera) to be recognized as eusocial. [29] [13] This species forms colonies in which a single female is fertilized, and is protected by many unfertilized females, which serve as workers excavating tunnels in trees. This species has ...
Although presocial species are much more common than eusocial species, eusocial species have disproportionately large populations. [ 6 ] The entomologist Charles D. Michener published a classification system for presociality in 1969, building on the earlier work of Suzanne Batra (who coined the words eusocial and quasisocial in 1966).
Different species are physiologically adapted to consume different foods that must be acquired in different ways, and the manner in which they feed must correspond to these unique characteristics. Rodents share common species-typical feeding behaviors (also known as order-typical, since all these creatures are members of the same order, rodentia).
