I once read the novel “Kappa” by the acclaimed Japanese novelist Akutagawa and was reminded of it when I was contemplating writing this blog about an embryonic diapause, a situation in which an embryo stays and waits in the womb to develop and to come out not until conditions are optimal for its emergence. In Akutagawa’s novel the offspring decides when and if they want to be born. Something a little similar to that actually exists amongst several species of mammals, although it seems that here the maternal organisms control and decide the best time for the young to be born. —>—>
The pouch: what a very useful structure!
By definition a “pouch” is a small sac-like container to store or keep things in. Biologically speaking, it is a pocket-like space in or on the body and the ‘pouches’ in our cheeks, for example, come to mind. They are useful for sucking up liquids (without these pouches as in the case of many carnivores like dogs and cats, liquids would have to be leapt up). —>—>
