Carapace

Carapace, like flesh, propagates from the flesh of a well-nourished organic ship. Carapace is more durable than flesh, and can be used as organic, chitinous armor.

Although carapace is stronger than flesh, it still has relatively low thermal and impact resistance. Carapace is capable of healing completely within several minutes, however, so long as it is supplied with oxygen- and nutrient-rich blood supplied by an artery network linking a heart, lungs, and stomach.

Carapace will automatically grow on the side of any vacuum-exposed flesh block, and automatically decay on the side of any air-exposed flesh block.

Requires: Oxygenated, nutrient-rich blood
