Title: Lapidequus umbellis (umbellate stone umbrella)
Planet: Briarey
The height at the withers is usually about one meter, there are individual specimens up to 1.5 meters in height. The hollow structure of bones and the general "lightweight" skeleton structure allows you to move freely in conditions of strong gravity. From a strong heat, the stone-stone is saved, resembling Briarey plants: it covers the legs (and sometimes the stomach) with cooling lava, which forms a dense crust that protects from excessive temperature. Also, a special air hood, located on the neck (starting from the eyes), pushes air to cool the brain.
On the back is a special leathery growth, with the help of which the stone can ... well, not that to fly. Rather - it's far to jump, some time to soar in the air and to some extent manage this steaming. Choosing a hot ascending flow of air, the stoneknock jumps, pushing back with strong hind legs, and opening its "dome" like an umbrella Mary Poppins. However, unlike the umbrella, this growth can shrink (like a dome of a jellyfish), making a jerk and allowing the stone-stone "to jump from one stream to another. It is vital to move from one island to another in search of food and security.
Omnivore (including cannibalism). Lips in front of the cornified, form a beak. With the help of this beak, the stone breaker splits a dense crust on plants, mushrooms, and also scrays the excess lava peel from its own body. However, its flexibility is rather limited, and so, over time, protective armor becomes an increasing burden. As a result, usually for the fourth-fifth year of life, the stone-stone becomes too slow to move fast enough - and then it is eaten by relatives. The life span of a stone-stone rarely exceeds five Briardian years.
Oviparous. In one masonry clay - up to three eggs. Clutches they arrange for more or less distant from the erupting volcano islets. After laying eggs, the parents guard the nest for four days (almost 100 terrestrial days). During this time, the kids manage to get through, get up on their feet and build up the primary protective layer. When they are strong enough to successfully use the umbrella-dome, the "family" disintegrates, everyone goes on an independent journey.
