The crayfish, Procambarus cubensis, placed in the central area of a plus-maze preferred to go forward in about 50% of trials; they chose the right or left arm in 20.7 and 18.9% of the trials, respectively.
The internal anatomy of freshwater crayfish is strictly bilaterally symmetric, with the conspicuous exception of the vertically oriented descending artery (sternal artery), which originates from the heart …
The crayfish conditioned to take a bloodworm with a claw did not demonstrate any stable preference of left or right claw in the course of the experiments, and the question of bilateral asymmetries within the …
We show clear evidence for monophyly of freshwater crayfish and for the sister-group relationship between crayfish and clawed lobsters.
This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
There was a strong correlation between the direction of U-turns and following turns ensuring the clockwise or anti-clockwise movements of the crayfish. Also we examined a possible …
Freshwater habitats throughout the United States harbor the richest diversity of crayfish in the world. These aquatic animals serve as important links in the food web, indicators of water quality, …

Crayfish[a] are freshwater crustaceans belonging to the infraorder Astacidea, which also contains lobsters. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills.
crayfish, any of numerous crustaceans (order Decapoda, phylum Arthropoda) constituting the families Astacidae (Northern Hemisphere), Parastacidae, and Austroastracidae (Southern Hemisphere). They are closely related to the lobster. Over half of the more than 500 species occur in North America.
Crayfish are freshwater, lobster-like decapod crustaceans that live in streams, rivers, lakes, wetlands, and burrows. They are omnivorous scavengers/predators, important ecosystem engineers, and are widely harvested for food; several species are invasive outside their native ranges.
Crayfish, also known as crawfish or crawdads, are a type of freshwater crustacean that belong to the same family as lobsters and crabs. These creatures are characterized by their elongated bodies, jointed appendages, and hard exoskeletons.
Crayfish, or crawfish, is the common name for almost exclusively freshwater crustaceans comprising the arthropod families Astacidae, Cambaridae, and Parastacidae, resembling small versions of the marine lobsters, to which they are closely related in the same decapod infraorder Astacidea.
Crayfish look like mini-lobsters, and range in size from a couple inches to over 2 feet. Crayfish bodies are divided into two parts; the cephalothorax, which is comprised of the head and thorax, and abdomen.
Crayfish are freshwater crustaceans that resemble small lobsters. Also known as crawfish or crawdads, they inhabit diverse aquatic environments globally. Found across most continents, excluding Antarctica and mainland Africa, they show remarkable adaptability to various freshwater conditions.
Crayfish, crawdad, crawfish, yabby, freshwater lobster and mudbug all refer to the same animal. There are over 640 species of crayfish in the world, with two centers of diversity, one in the Southeastern United States and the other in Southern Australia.
Freshwater habitats throughout the United States harbor the richest diversity of crayfish in the world. These aquatic animals serve as important links in the food web, indicators of water quality, and a food source for humans. Crayfish are threatened by habitat loss, pollution, and invasive species.
Crayfish are fascinating aquatic invertebrates that can be found in various freshwater habitats, such as lakes, streams, and rivers. They play a crucial role in their ecosystems, serving as a food source for a wide range of animal species, including bass and catfish.
Crayfish have a long and fascinating evolutionary history that stretches back over 200 million years. These freshwater dwellers are part of a larger group known as crustaceans, which also includes crabs, lobsters, and shrimp.
