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]
While most incidences of carcinization are in aquatic Anomura populations, it has evolved in the planet’s largest land-dwelling invertebrate, Coconut crabs. A number of true crab-like features, such as a wide carapace, and a low abdomen with strong supporting legs, allow these crustaceans to wield muscular claws and manipulate their ...
Many invertebrate taxa have a greater number and diversity of species than the entire subphylum of Vertebrata. [2] Invertebrates vary widely in size, from 10 μm (0.0004 in) [3] myxozoans to the 9–10 m (30–33 ft) colossal squid. [4]
A different example is seen in mature female fruit flies, Drosophila melanogaster, who are very attractive but their level of attractiveness decreases by half or more after three minutes of mating. [15] Males release a compound, 7-tricosene, into the female during courtship that lowers female attractiveness.
Male members of cannibalistic species have adapted different mating tactics as a mechanism for escaping the cannibalistic tendencies of their female counterparts. Current theory suggests antagonistic co-evolution has occurred, where adaptations seen in one sex produce adaptations in the other. [ 8 ]
In subsocial taxa, parents care for their young for some length of time. Even if the period of care is very short, the animal is still described as subsocial. If adult animals associate with other adults, they are not called subsocial, but are ranked in some other classification according to their social behaviours.

In biology, polymorphism [1] is the occurrence of two or more clearly different morphs or forms, also referred to as alternative phenotypes, in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating).
