云斑厚纹蟹（学名：Pachygrapsus marmoratus）是厚纹蟹属的一种螃蟹，分布于黑海、地中海和大西洋的部分地区。
特征
[编辑]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
[编辑]云斑厚纹蟹广泛分布在南欧[4]的黑海至摩洛哥海岸，并沿葡萄牙、西班牙及法国的大西洋海岸[5]，与及在北至英国南安普敦的英吉利海峡出没。[5]它们的分布地扩展可能与全球暖化有关。[6]
生态
[编辑]云斑厚纹蟹是杂食性的，主要吃其栖息地内丰富的藻类及动物。它们最喜欢吃蚌、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]
