This is kurungkoeng (Aceh) / crab.
This type of crab is very easy to find at night in the forest area manggrov.
These animals live in large shrimp nests or gateuk (Aceh).
These are some beautiful photos I have seen to friends in steemits.
I hope my friends are happy to see it .
This is not a pipe or tower, it's a nest of crabs
GATEUK nest (ACEH) is similar to a mountain, this nest is used as a place of this crab
