Evolved from T. primacrushus they were pushed to zone 13 due to the predation of R. cancovorem, T. katharagnathus and T. killacrabus. Since they have gills that can breathe in saltwater they are able to breathe underwater and they adapted to live underwater with lighter built legs as it is easier to walk on water and brooding eggs and young are acclimated to surviving in saltwater instead of needing brackish. They also have change their diet which they still eat rocks but adapted to eating their own molt to harden their shell and the native polyphs in zone 13. To improve filtering salt in the sat water there are more gill filtering parts for them to filter salt

Found in zone 13 they have a carapace width of 15cm with a carapace length of 6cm they climb on rocks and live solitarily. They feed on A.okeanus, small rocks, R. magnideus and R. titanokelpus. This species are bottom dwellers, they are mostly found hiding in crevasses to avoid getting eaten by potential predators like R. gigas and R. parvus. They are now found feeding anytime during night, dusk, morning or day but they prefer dawn dusk and at night because they are less possible to be eaten or spotted and can use their smell to find food. Males and females have a coloration of sand and grey to mimic the bottom of the water. To tolerate the new salty environment they simply filter it from its gills then spit it out. Their claws still remain the same size even though they have a lighter build

When breeding females release pheromones in the water which the males are able to taste and smell the pheromones in the water so it is able to find the female. When the male finds the female it will mate and the female will carry the eggs(up to 50-70 eggs only 30-45 survive due to predation). Eggs and babies are adapted to tolerate the saltwater and do not need brackish and not need to travel to zone J to brood eggs or hatch young. The eggs have a thin chitin layer to protect itself from saltwater getting in. Once the eggs hatch the babies go fully independent and fend for themselves.
