The Cretaceous crab revolution was a major diversification event of brachyuran crustaceans (also known as true crabs) that took place during the Cretaceous period, from 145 to 66 million years ago. [ 1 ] [ 2 ] Nearly 80% of modern groups of crabs originated during this event. [ 3 ]
Crabs and false crabs are best suited to escape by ground pursuit in comparison to the quick aquatic escape provided by the caridoid escape reaction. Porcelain crabs' closest relatives are squat lobsters , taxa which occupy a morphological middle ground, described by Keiler et. al. as "half-carcinized" due to their partially flexed pleons and ...

The remaining group, called Pleocyemata, then diverged between the swimming shrimp groupings and the crawling/walking group called Reptantia, consisting of lobsters and crabs. High species diversification can be traced to the Jurassic and Cretaceous periods, which coincides with the rise and spread of modern coral reefs , a key habitat for the ...
The photo made headlines, and then a new image surfaced showing the giant crab dangerously close to two young children. The photo was posted on a site called Weird Whistable , and the Daily ...
Dorippoidea is a superfamily of crabs. [1] The earliest fossils attributable to the Dorippoidea date from the Late Cretaceous. [2] There are two known species of Dorippids, Dorippe quadridens and Dorippoides facchino. They are found in the shallow sand and mud substrate in coastal waters.
