  2. Sexual selection in scaled reptiles - Wikipedia

    en.wikipedia.org/wiki/Sexual_selection_in_scaled...

    Sea snake scales differ from that of terrestrial snakes because they are rugose and wrinkled. Male sea snakes scale rugosity is more developed than that of the female snakes. The male turtle headed sea snake, Emydocephalus annulatus, provides an interesting case study because of their unique scales. [35]

  3. Snake detection theory - Wikipedia

    en.wikipedia.org/wiki/Snake_Detection_Theory

    The snake detection theory, [1] [2] [3] also sometimes called the snake detection hypothesis, suggests that snakes have contributed to the evolution of primates' visual system. According to the theory, predatory pressure from snakes has selected individuals who are better able to recognize them, improving their survival chances and therefore ...

  4. Sexual cannibalism - Wikipedia

    en.wikipedia.org/wiki/Sexual_cannibalism

    Sexual dimorphism in size has been proposed as an explanation for the widespread nature of sexual cannibalism across distantly related arthropods. Typically, male birds and mammals are larger as they participate in male-male competition. [56] However, in arthropods this size dimorphism ratio is reversed, with females commonly larger than males.

    They found that snakes experienced a burst of innovation early in their history and have evolved at a rate perhaps three to five times faster than their lizard cousins.

    In other species, males that are smaller than females have higher fitness. As such, many sex-specific morphological adaptations (for example, in Dytiscidae diving beetles, females have setose dorsal furrows that males do not and males have suction cups on their forelegs that females do not [18]) are sexual dimorphisms caused by sexual coercion.

  8. Non-reproductive sexual behavior in animals - Wikipedia

    en.wikipedia.org/wiki/Non-reproductive_sexual...

    Animal non-reproductive sexual behavior encompasses sexual activities that non-human animals participate in which do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals, recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals.

  9. Hemipenis - Wikipedia

    en.wikipedia.org/wiki/Hemipenis

    The hemipenis is the intromittent organ of Squamata, [4] which is the second largest order of vertebrates with over 9,000 species distributed around the world. They differ from the intromittent organs of most other amniotes such as mammals, archosaurs and turtles that have a single genital tubercle, as squamates have the paired genitalia remaining separate.
