Ballpede

Stingerpede kept getting eaten by the Helmeted Parrotworm so rather than use its stinger some curved up to protect themselves. These evolved into the Ballpedes. Their shells are thick and their spikes sharp. Even a Parrotworms beak cannot break its shell. Its spends its day scavenging for scraps at the bottom of the reef. Its favorite food is Malakommalis infected animals. It has grown an immunity to the spores and actually uses them to strengthen its shell thanks to the ridged nature of the Malakommalis. There is a price however. The more they curled up the more the shell will stay in the curled up position. Eventually old Ballpedes will be forever stuck that way due to the crystal build up in the exoskeleton segments. Thus having to crawl around using only their claws. In short they actually help spread the Malakommalis the more predators bite their infected shells.
