特征

云斑厚纹蟹的甲壳呈方形,长2.2-3.6厘米,呈深紫褐色,有黄色的大理石纹。[2]它们的甲壳上每边有三个锯齿,这与地中海的其他厚纹蟹属生物有所不同。[2][3]它们能够移动得很快,飞快的走入石缝之间,很难捕捉。[2]

分布

云斑厚纹蟹广泛分布在南欧[4]黑海摩洛哥海岸,并沿葡萄牙西班牙法国大西洋海岸[5],与及在北至英国南安普敦英吉利海峡出没。[5]它们的分布地扩展可能与全球暖化有关。[6]

生态

云斑厚纹蟹是杂食性的,主要吃其栖息地内丰富的藻类动物。它们最喜欢吃帽贝及同种相食。[4]它们只会使用一种方式攻击帽贝,但往往不成功。[7]在有荫的海边,它们会较少吃蚌,取而代之是吃藤壶[8]

云斑厚纹蟹的天敌包括麝香章鱼[9]

云斑厚纹蟹的幼体是浮游动物,只可以生存31天。这样使得它们群落间有高度的基因流,及广泛散布到新的地区。[10]
