The Pyrocoral is a mossy material wrapped around a grey rock formation with a wide base that splits off into multiple branching sections. The coral itself is wrapped around the rock like a net and is green in color. At the tips of the rock's branching sections, exposed lava can be seen giving off a faint yellow glow.
Data Bank Entry
This coral species is unlike any other encountered on 4546B in so far as it relies on magma flow rather than water current to deliver nutrients. As lava rises up from the planet's core and erupts at vents, this coral forms around the base until eventually it has surrounded the entire vent. Lava is then funneled up through the coral, allowing it to siphon minerals and heat as it goes.
