Ringed Crastrum

Splitting from its ancestor, the ringed crastrum has moved onto the eastern coast of both Drake and Darwin. Forming thick clusters on all available surfaces, they reproduce rapidly via budding. As they age, their central body develops rings as it grows, with one ring equaling a week of growth, and with thicker ones indicating weeks of good growth and thinner ones indicating otherwise. Their shell keeps them protected while their spikes produce a neurotoxin that protects them from potential predators. They tend to live near the surface and try to avoid murky water.
