Coral rolloliths can occur in really unexpected species

We tend to think of most corals as being stationary, one-sided colonies of creatures but in some habitats, an abundance of corals occur as living tumbleweeds. When colonial corals occur as unattached rolling living rocks they are called ‘rolloliths’ – while diving one particular site during theFluval Sea Flores探险we observed an incredible diversity of coral genera living this way.

大约一年前，我们与您分享了无关Gonioporacolony来自澳大利亚的整个侧面都有组织，还有一个水族馆种植红色的花盆珊瑚它也发展成为自由滚动的球形殖民地。以前是rollolith现象已经在其他更坚硬的石质珊瑚物种中进行了记录，但我们在这里为该列表添加了更多属。

这species of stony corals which are naturally tough in skeleton and grow into submassive shapes likeCyphastrea，poritesandFavitesare not surprising to see growing into rolloliths. But the species which really surprised us when we encountered them in their tumbleweed form were unexpected species like蒙蒂托拉还有一件特别令人敬畏的一件Pachyseris Rugosa。

这rollolithic蒙蒂托拉仅在某些地方进行了轻微的分支，但它几乎不符合该账单，因为它确实具有覆盖其所有表面和底面的组织，但是非球形的形状可阻止该菌落在除电流最强之外的所有外部滚动过多。这Pachyseris另一方面，rolllith的外观真的很酷，这种珊瑚物种的独特图案涵盖了圆形菌落的各个侧面，使其看起来像某种奇怪的生活水晶。

鉴于发现了这些独特的活珊瑚滚筒冰草，只要在正确的栖息地出现，几乎所有种类的石质珊瑚珊瑚生物都会出现在正确的栖息地，并以适当数量的波动作用和水运动，我们就不会感到惊讶。Pigonhole殖民地石质珊瑚作为底栖礁的生物很容易，尽管大多数人都是珊瑚，但珊瑚仍然可以以它们的韧性和对非常规生活方式的适应性感到惊讶。
