The shell of Magmish eggs are comprised of molten lava that has hardened. Encased within is a molten yolk that prevents anyone from making skin contact to the shell without suffering from third degree burns.
Magmish are remarkable creatures in that they dwell within Ark's harshest yet most striking feature; the Volcano. The Science and Research Center has been taking great strides in its research on Magmish, trying to uncover the amazing evolutionary process that has allowed the creature to survive in pure magma. The only threat to Magmish is, ironically, the Volcano itself upon eruption.
