Triarii Lizardworm

The triarii lizardworm split from the phalanx lizardworm as a result of its primary prey, the neckeye, evolving to become almost twice its size. The massive nine-point-six meter tall orbitree neckeye provided enough food for the lizardworm to grow to five-point-five meters in length. In order to better cope with its main source of prey's new camouflage abilities one pair of the lizardworm's eyes have grown larger and more powerful to help it spot prey. Two of the lizardworm's claws have grown longer and stronger; these are used to scrape suspicious looking mega orbitrees. If the tree bleeds the triarii lizardworm knows that it has found a hiding neckeye and calls its pack of three to six members to help it take down the creature. The size of the neckeye makes pack work a requirement, but taking down neckeyes is somewhat easier, thanks to the creatures lessened sociality.

The orbitree itself is the most dominant plant in the region, so the triarii species has evolved a lighter pigment tone to better match it. Its ancestor, the phalanx lizardworm has been forced to rely more on scavenging, since it cannot compete for neckeyes at its size. The triarii on the other hand has abandoned scavenging completely, which means competition for scavengers is low.
