Biomechanical–substrate interface: mud cracking by soft worms. The initial impression of worms as squishy, helpless wrigglers must be fairly far off the mark, given that they can create lasting tunnels through a wide array of substrates. This happens in different ways depending on the size of the worm and characteristics of the environment.Mud cracks constituted a spectacular feature representative of the contraction stress. These ephemeral features were found to (re)open after a few days of dewatering and to (re)heal during subsequent wetting. Fig. 9. Ground photograph of mud cracks which constitute preferential colonization networks by Avicennia germinans mangroves.Root casts and mud cracks form when the lake's shoreline recedes, exposing finer silt and clay to air.
