Families Corystidae and Thiidae comprise 13 species of burrowing crabs, and only 2 of them inhabits the ICES area. These species are Corystes cassivelaunus, belonging to the family Corystidae, and Thia scutellata in the family Thiidae. Both are warm-water species and inhabit the sublittoral zone in sandy bottoms. The larval series of the two species is known to include two phases: zoea and megalopa. The zoeal stages are the dispersal phase, and the megalopa is the dispersive and specialised recruitment phase. This leaflet provides the distinctive characteristics of the larval stages for C. cassivelaunus and T. scutellata, and illustrated keys are included to improve the identification of zoeae and megalopa stages SI
