Some can use these wings to fly; however, hybrid High Entia such as Melia, who is half-Homs, have smaller wings. The Shi'ar from Marvel Comics, a species of cold-blooded humanoids of avian descent; they resemble humans with feathered crests atop their heads in lieu of hair. Birdperson, a character from the television series Rick and Morty, is a ...
They usually do so when the temperature is warmer and will re-emerge in the late summer or early fall. [5] Mosquitoes also are reported to undergo aestivation. [6] False honey ants are well known for being winter active and aestivate in temperate climates. Bogong moths will aestivate over the summer to avoid the heat and lack of food sources. [7]
Invertebrates cells fire in response to similar stimuli as mammals, such as tissue trauma, high temperature, or changes in pH. The first invertebrate in which a neuron cell was identified was the medicinal leech, Hirudo medicinalis. [14] [15] Learning and memory using nociceptors have been described in the sea hare, Aplysia.
A tau emerald (Hemicordulia tau) dragonfly has flight muscles attached directly to its wings. Insects are the only group of invertebrates that have evolved wings and flight. Insects first flew in the Carboniferous, some 300 to 350 million years ago, making them the first animals to evolve flight. Wings may have evolved from appendages on the ...
Two Schistocerca gregaria nymphs beside an adult. In biology, a nymph (from Ancient Greek νύμφα nūmphē meaning "bride") is the juvenile form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (hemimetabolism) before reaching its adult stage. [1]
A cynocephalus. From the Nuremberg Chronicle (1493).. The characteristic of cynocephaly, or cynocephalus (/ s aɪ n oʊ ˈ s ɛ f ə l i /), having the head of a canid, typically that of a dog or jackal, is a widely attested mythical phenomenon existing in many different forms and contexts.
Some reptiles, such as the sand lizard of Europe, have eyespots; in the sand lizard's case, there is a row of spots along the back, and a row on each side. [12]Many species of cat, including Geoffroy's cats, jungle cats, pampas cats, and servals, have white markings, whether spots or bars, on the backs of their ears; it is possible that these signal "follow me" to the young of the species.
The more advanced groups making up the Neoptera have foldable wings, and their muscles act on the thorax wall and power the wings indirectly. [ 1 ] : 22–24 These muscles can contract multiple times for each single nerve impulse, allowing the wings to beat faster than would ordinarily be possible.
