Eve has several beaches along its continental coastlines and terrain of each one varies greatly. One some rocky beaches, strange pursuits can be observed among predator and prey, such as the one depicted above.
The Koronkazella (from Chóros and Nkazélla meaning Space and Gazelle respectively), also known to the general public as the Gazelle of Seth, are 3 meter tall herbivore that patrol the rough terrain at low tide, looking for moss and algae clinging to rocks, upon which they feed. Although most of their body is encased in an exoskeleton, their heads, necks and translucent forelimbs are exposed to the air. It belongs to the same family as the Loutroteras and must remain in an environment with high levels of humidity in order keep their bodies from drying out. Therefore, their anatomy restricts them to the coastline of the Northwest Continent.
Although solitary, Gazelles of Seth have ways to protect themselves from danger. Their long ears not only detect approaching danger but can also detect the scent of other animals. Large ears and sensitive hearing are vital to tune out the noise of crashing waves onto the beach. It is also enables them to remain alert to potential rock slides when feeding along steep cliffs. The shell area around their shoulders also supports large spikes that intimidate old or less intelligent predators. Their primary weapon however is their elongated legs that make up more than half of their height. Not only does it allow them to run quickly from danger, but they can even deliver violent kicks when cornered. These weapons are vital because there are two species of predators that feed on it, sometimes at the same time.
The first and larger of the two is the 6 and a half meter long Ostrakosaurus (meaning hard shell/oyster lizard). This dinosaur-like carnivore has all the tools need to catch and kill prey. The cone shaped horn on its head is extremely though and can be used like a battering ram to stun animals or even damage their armor. It also has free forelimbs to grasp prey although their dexterity is extremely limited. The upper arm is highly reduced in length and can only move away from the body. Its forearms can rotate on the elbow joint fairly well but lack any digits to manipulate food. Instead, they are covered with numerous spikes pointing forward and backwards. They are mainly used to get a grip on its quarry as the spikes prevent escape in any direction. This allows it to use its main weapon, a nutcracker-shaped mouth, to deliver the finishing blow by breaking the animal open and spilling the viscera. Although it cannot run nearly as fast as the Gazelle of Seth, the equally solitary Ostrakosaurus have good stamina and can jog closely behind their prey and wait for it to tire out. It doesn’t need to run as fast as its prey because another predator performs that role for it.
Only the second predator, the Deinoyaina (meaning terrible hyena), is able to keep up with a running Gazelle of Seth. Unlike Ostrakosaurus, these are cooperative hunters and a pack can make up of 2 to 30 individuals. Relatively agile for a creature with no backbone, they can sprint up to 70 km/h, as fast as greyhound, but usually settle for an average speed of 40 km/h, especially on rocky terrain. Their own arsenal of weapons makes them almost nightmarish in appearance. The upper and lower jaws of a Deinoyaina each contain a row of sharp ridges that act like teeth, although they grow along the length of the jaw rather than around it. This allows them to bite through soft tissue like scissors cut through paper. Their tails also support black maces that allow them to trip running game or even break kneecaps. To be able to run on rough terrain, their feet are hooved and the thundering sounds they make while running together is eerily similar to those of horses.
One may wondering why those two species of predators are so often found going after the same target but rarely fight one another. The theory is that these animals are actually picky eaters and only like specific portions of animals such as the Gazelle of Seth. Indeed, the Ostrakosaurus has always been focusing its attention on the main body where the organs and fat storage are found. Meanwhile, Deinoyainas target the forward portion of the body, even while hunting, inflicting deep gashes in the necks of their prey. Their jaws aren’t able to pry open the tough shells of animals so all they can feed on is the softer tissues and ganglions. Having no reason to fight, the two predators simply ignore each other and focus on their favourite foods.
"The Ostrakosaurus is based on a Ceratosaurus mixed with a nutcracker and may have had some inspiration from the Pokemon Tyranitar. Deinoyainas was inspired by both Hyenas and Cape Hunting Dogs as well as a species of extinct shark with a similarly built jaw. Gazelles of Set are based on cone shells, gazelles, ostriches and the Egyptian got Seth (hence the common name)."
Both predators have some form of protection of their own; the Ostrakosaurus has rear pointing spikes and the Deinoyainas are covered with osteoderms. This is because both are hunted by the massive Kolonadankan. tapejara.deviantart.com/art/Pl…
Gazelles of Seth, like their relatives, lack a spur. It is not yet known how these animals reproduce.
unlike most life forms on Eve, Ostrakosaurus lack toenails.
Deinoyainas have a mane running along their necks, a feature unique among Planet Eve's lifeforms. Its function is unknown.
