The Seventy-second Beast.
The beast has become a flightless arboreal trilobite! It will hide its head underneath its carapace and use its lures to attract prey, mimicking mating or injured insects. It has an (unintentional) resemblance to the Opabinia.
The Seventieth Beast.
The Beast has become a spindly hunter! Its foremost limbs have developed into spear-tipped lures and its front-facing arms have developed into prickly grabbers. The rest of the body has camouflaged to blend in with brush or tree bark. It can climb well and glide from place to place.
