Rhabdite

Rhabdites (from Greek, rhabdos, rod) are rodlike structures in the cells of the epidermis or underlying parenchyma in certain turbellarians, and in the epidermis of nemerteans.^[1] They are discharged in mucous secretions. They are a defensive mechanism, which dissolve in water, and they are distasteful to most animals who would prey on rhabditid worms. In nemerteans, rhabdites form mucus on which the animals glide.^[2]
