Creature Name: Dragon (dra gun)
Height: 1.9 m
Mass: 250 kg
The Dragon is a very close relative of the Alcoon. They are about the same size and live in similar environments. Morphologically they are almost identical. However, where the Alcoon has legs the Dragon has a very strong tail for swimming. On the other hand both species have small fins, which are next to useless in the Alcoon. Indications are that the two species both evolved from an amphibious creature, one that lived both in and out of the lava. The species diverged into a completely terrestrial species and a completely lava-based species.
Dragons spend most of their day deep in the lava. Their skin is very thick and leathery, allowing them to live in the lava without being burnt alive or their blood boiling. When they sense potential prey they surface and spit specialized projectiles at the possible meal. The Dragon makes these projectiles by sucking in lava, then allowing it to cool around a bubble full of hydrogen gas. The hydrogen gas is extracted from hydrocarbons by enzyme in the Dragons mouth pouches. The dried lava creates a thin rocky crust over the hydrogen gas. The lava in Norfair contains a large amount of iron, and as it cools iron fragments precipitate out. This means the rocky crust has small iron filings mixed in with it. The Dragon then uses bioelectrical magnets in its snout to accelerate the iron in the rock, and thus the rock itself, out of its snout at high speed.
When the rock hits its prey the rock breaks open, releasing the hydrogen gas, which is ignited by the extreme temperatures in Norfair. This creates a small explosion that will kill most creatures in Norfair in a few shots. The Dragons are capable of storing a few shots in its pouch at a time, but when those are used up it has to submerge itself again in order to take in more lava. When the prey is dead the Dragon will swim up to it and inject it with digestive juices through the holes created by the explosions. When the prey has been liquefied the Dragon sucks it up.Dragons reproduce sexually. Dragons usually mate for life, with the mating pair staying near each other and sharing prey. This allows them to work as a team and not have to compete for meals. Dragons usually don't have to fight over their kills, as a pair of Dragons is too much for a potential thief to deal with. Dragon females produce small clusters of eggs, which the female divides up, both partners staying close to half the eggs.
