Fleas in Santharia

Together with miraran i though that we dont have fleas in snathria so he said to me to do them and here they are:

Overview
Flea is the common name for any of the small wingless insects that are known in the entire Santharia world from the Ice Lands to the Deserts of Aeruillin). Fleas are external parasites, living by hematophagy or off the blood of mammals and birds, sucking it with its mouth parts. Fleas are very resistant parasites and their morphology is adapted to the only thing they do in their sucking blood life: sucking blood. Places were fleas suck blood normally make irritations and scratching.
Appearance:
Fleas are small (half Nailsbreath inch) (half and a bit Nailbreath long), agile, usually dark coloured (e.g. the reddish-brown of the cat flea), wingless insects with tube-like mouthparts adapted to feeding on the blood of their hosts. Their bodies are laterally compressed, (flattened side to side) permitting easy movement through the hairs (or feathers etc.) on the host's body. Their legs are long, the hind pair well adapted for jumping (vertically up to seventeen Nailsbreath high); around 200 times their own body length, making the flea the best jumper out of all animals (in comparison to body size). The flea body is hard, polished, and covered with many hairs and short spines directed backward, allowing the flea a smooth passage through the hairs of its host. Its tough body is able to withstand great pressure, likely an adaptation to survive scratching and smashing by bigger hosts. Even hard squeezing between the fingers is normally insufficient to kill the flea; it may be necessary to crush them between the fingernails or roll them between the fingers.
Fleas lay tiny white oval shaped eggs. Their larvae are small and pale with bristles covering their worm-like body. They are without eyes, and have mouthparts adapted to chewing. While the adult flea's diet consists solely of blood, their larvae feed on various organic matter including the feces of mature fleas. In the pupae phase the larvae are enclosed in a silken, debris covered cocoon.
Special Abilities
Fleas are small animals and the only ability they can do is sucking blood.
Even there it's known that like mosquitoes, fleas can transmit sicknesses and epidemies very fast, because they drink blood of one host that can have the sickness and by sucking the blood of another host they can spread the sickness.
Territory
Fleas can be found in all Caelereth and big cities like Macogg are full of them, specially in dirty and dark places (e.g. taverns, streets, old gardens, etc)
Habitat & Behavior
After its larval state and when the flea reaches adulthood its primary goal is to find blood - adult fleas must feed on blood in order to reproduce. Adult fleas only have around a week to find food once they emerge, though they can survive two months to a year between meals. A flea population is unevenly distributed, with more eggs than worms or adults. Their total life cycle can take as little as two weeks, but may be lengthened to many months if conditions are favorable. Female fleas can lay 500 or more eggs over their life, allowing for phenomenal growth rates.
Fleas habit in dark places, dirty and full of mammals and birds were it can suck a lot of blood so the ideal place to found fleas is in taverns.
Diet:
Fleas feed exclusively on blood, being that the aliment that the entire animal is designed to fee on. From the leg to the mouth all the animals focus on sucking blood smoothly and fast.
Mating:
Fleas are insects that have many stages of life, going through the four life cycle stages of embryo, larva, pupa and flea (adult). The flea life cycle begins when the female lays the eggs after feeding. Adult fleas must feed on blood before they can become capable of reproduction. Eggs are laid in batches of up to 20 or so, usually on the host itself, which easily roll onto the ground. As such, areas where the host rests and sleeps become one of the primary habitats of eggs and developing fleas. The eggs take around two days to two weeks to hatch
Flea larvae emerge from the eggs to feed on any available organic material such as dead insects, feces and vegetable matter. They are blind and avoid sunlight, keeping to dark places like sand, cracks and crevices, and bedding. Given an adequate supply of food, larvae should pupate within 1-2 weeks. After going through three larval stages they spin a silken cocoon. After another week or two the adult flea is fully developed and ready to emerge from the cocoon. They may however remain resting during this period until they receive a signal that a host is near - vibrations (including sound), heat are all signals indicating the probable presence of a host. Fleas are known to go through winter in the larval or pupal stages.

Myth/Lore:
No folk is known to venerate fleas only one little tribe in Cyhalloi, The Kasumarii tribe Darkpriests. As their Shadowmancy has the power to suck life they venerate and respect the flea by having the power of sucking the life of other beings, and more important, unseen.

“Those who dabble in Shadowmancy learn how to bend light around them, to cloak themselves in shadow, and have the frightening knowledge to turn the very shadows around an individual into spiritual ghosts that have the power to literally suck the life out of the one whom they have attacked.”
Excert from The Kurakii men, Darkpriests

Another thing:

We have gooses in santharia i know, but we dont have ducks. Why don´t Santharia doesn´t has ducks, domestic or wild? Someone could do something about ducks.
There aren´t domesticated birds like parrots,canaries, and others.
