Here is some stuff about the kwogos (and to some degree, other knogos species.)
The Kwogos lack a proper comparison to earth creatures. They are omnivorous, bipedal creatures who live in large pack like communities which are composed of mated pairs and usually ruled by the eldest females while the physically slightly stronger males usually protect the pack.
The ancestors of the knogos species resembled amphibians, but the modern knogos species are more akin to the dinosaurs of earth. They have, rough, somewhat rubbery skin, that is covered by a thin layer of oil. They communicate vocally, and trough body language, which is mostly done trough their facial expressions. They can emit wide range of noises, with the aid of their lips, tongue and most importantly, trough a bladder like organ on their forehead, which amplifies the voices they create.
The Knogos species breed somewhat like amphibians. Their eggs are covered by a thick, rubbery and translucent membrane, and even thicker layer of slime, which both protect the developing embryo. Unlike amphibians, the knogos species protect these eggs, carrying them in a "pouch" they form by folding their tail against their belly. The underside of the tail excretes nutrient rich slime, which keeps the eggs moist, as well as delivers extra nutrients to the developing embryo. The number and size of the eggs that are laid depends on the knogos species. Kwogos usually lay 1-3 eggs, which are roughly the size of a human fist.
The eggs develop quite fast, and the larvae emerge from them in few weeks, or in about a month, depending on the species. The larvae will remain in the pouch, (which can be formed by both females and males, allowing the parents to both care for the young) growing while feeding on the nutrient slime of the parent. The larval knogos resemble tadpoles, to some degree (they never have gills though), but due to their quick growth rate, this resemblance vanishes in under a week.
