There are crabs in salt water; there are crabs in fresh water. And there are crabs in the mangrove swamps parallel to the oceans (these swamps alternate between fresh water and salt water depending on the height of the tide and whether it is dry season or wet season).
In Guatemala there are two great areas to see and experience crabs: One is Manchon, a preservation area parallel to the Pacific Ocean managed by CONAP.

This is the Crab Rhizophora in Manchon Guamuchal, Retalhuleu, Guatemala.

The other area of diverse crab species is Canal de Chiquimulilla, from the Monterrico to Hawaii (Guatemalan Hawaii; not the islands of same name). The ones on the beach will really entertain you. These waterways are managed by CECON.

This specie of crab lives in the Canal of Chiquimulilla, Monterico - Santa Rosa, Guatemala.
Then there are giant, literally enormous crabs in other eco-systems. These were used as headdress decorations by the deities and kings of Bilbao, Cotzumalhuapa civilization. This is a non-Maya civilization of Guatemala.
So crabs are important to preserve, both the animals themselves, and their fragile eco-systems. Later this year we will be preparing photo-albums on crabs of Guatemala to help students, professors, environmentalists, and university and government plant and animal protection agencies.
