Interesting Facts About Crabs
Crabs are highly active creatures that exhibit intricate behavioral patterns, including communication through drumming or waving their pincers. They are known for their tendency to display aggression towards each other, with males frequently engaging in combat to establish dominance and gain access to females.
Here are some interesting facts:
The Evolution of Crabs
The process of an evolutionary transition from a crustacean resembling a lobster to a crab is referred to as "carcinization," which represents a significant morphological transformation.
Interestingly, the crab-like body shape has independently evolved in multiple lineages within the Decapoda order, indicating convergent evolution.
Throughout the course of evolution, five distinct groups within the decapod family have independently undergone transformations that resulted in the development of crab-like characteristics. The emergence of specific traits in response to varying environmental conditions has led to the gradual evolution of multiple organisms into crab-like forms.
Interestingly, crabs also possess the unique ability to revert or modify their crab-like traits, presenting an intriguing phenomenon where they can "un-evolve" their distinctive characteristics.
Fishing and Cooking
To prepare live crabs for cooking, it is recommended to briefly submerge them using long BBQ tongs into a bowl of ice water. This action serves to temporarily stun the crabs, reducing their awareness of the subsequent cooking process.
To begin, heat water until it reaches a boiling point, and incorporate salt and any desired seasonings. Swiftly place the crab into the boiling water, ensuring it returns to a boil promptly, and cook until the crab floats, typically for a duration of 10 to 15 minutes.
Subsequently, extract the crab from the water and allow it to cool before serving.
