This egg appears to be made out of rocky plates.
At over ten meters long and armed with shearing plates instead of teeth, an adult dunkleosteus is a near-unstoppable force in the volcanic waters where it resides. Though not particularly fast swimmers, dunkleosteus can open and extend their jaws to snap up prey before an onlooker can blink. These massive fish have forgone sharpened teeth for a bladelike bony projection that extends off the lower jaw and parts of the cranium and allows the fish to easily pierce through the toughest hides. Abyssal dunkleosteus are unusual in that they are not animals as much as they are living rock. They are thought to have originally come from volcanoes, somehow made living through a very ancient earth magic related to that which produced vitons and amphipteres, though much darker. Eggs are rare, but unlike the adults and hatchlings, can withstand cold waters, and even be taken on land. An older dunkleosteus may sacrifice some of its own magma to produce an egg, but this is done so rarely that their population grows slowly. If the volcanic regions where a group of dunkleosteus live become dormant, the group will travel to the warmer surface and migrate to a new location. They can only go for a month without volcanic heat, even if warmed by the sun, before they begin to freeze. The heat of the abyssal dunkleosteus is also potent if used to heat magical potions, though the only potions able to withstand the heat are those of forbidden dark magics.
