It is a specific form of convergent evolution, where differing families of animals (in this case, nominally across the crustacea) develop a tendency towards developing a 'crab' bodyplan to a greater degree than their origins would suggest. 94-390 Ukee Street According to Know Your Meme, it was around October of 2020 that carcinization memes began appearing in full force as a common search result. circumspect: [adjective] careful to consider all circumstances and possible consequences : prudent.

The Anomura presents the greatest degree of morphological disparity in the decapod Crustacea, with body forms ranging from the symmetrical and asymmetrical hermit crabs to squat lobsters and king crabs.

The pleon is largely hidden under the crab body, unlike the pleon of the . This includes underground and on the dark side of Earth. "True crabs" (Brachyura) form just a small subset of the Crustacea subphylum, and the Cancer genus is a subset of that, yet there appears to be something about the bodyplan and even resulting behaviour that has meant a number of species have arisen from alternate areas of the family tree that are now trivially indistinguishable without extensive study. They are humans' best friends. Carcinization, or the process of becoming a crab, has been, and continues to be, a focal point of anomuran evolutionary hypoth eses. Curiously, not only did the crab-like habitus evolve independently from the 'true' crabs (Brachyura), it also evolved three times independently within anomurans.

Anagrams of carcinization: Crabs have long stumped taxonomists who have invariably misclassified species as true or false crabs due to their striking similarities. In the sixth century, the Byzantine Emperor Justinian oversaw the consolidation of Roman civil law. The compact body shape of a crab may also make it easier to scuttle about on the ocean floor, which could help crabs evade predators, and crabs may find it easier to fit into tight spaces as a way to hide from predators. Traditional examples of carcinization in the Anomura . But, over time, they developed third eyelids and long eyelashes to keep sand out of their eyes and humps that store fat and water that can sustain them when nourishment is inaccessible.
