Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail", usually hidden entirely under the thorax. They live in all the world's oceans, in fresh water, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers.

We have observed Crab 80 times world wild from 2021-05-16 till this date with the last observation being in 2022-07-10 in Cuba.

Our data suggest that Crab are highly active in October, July and September world wild but differences observed on country level, while the lowest activity observed on March and April.

We noticed also the top 3 countries to observe Crab in are: Brazil, Philippines and Pakistan respectively.
