Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen), 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. Many other animals with similar names – such as hermit crabs, king crabs, porcelain crabs, horseshoe crabs, stone crabs, and crab lice – are not true crabs, but many have evolved features similar to true crabs through a process known as carcinisation.
Cobra is the common name of various elapid snakes, most of which belong to the genus Naja.
A peltast was a type of light infantry, originating in Thrace and Paeonia, who often served as skirmishers in Hellenic and Hellenistic armies. In the Medieval period, the same term was used for a type of Byzantine infantryman.
Horseshoe crabs are marine and brackish water arthropods of the family Limulidae, suborder Xiphosurida, and order Xiphosura. Their popular name is a misnomer, as they are not true crabs, nor even crustaceans, as crabs are, but a different order of arthropod.
The Chinese mitten crab, also known as the Shanghai hairy crab, is a medium-sized burrowing crab that is named for its furry claws, which resemble mittens. It is native to rivers, estuaries and other coastal habitats of East Asia from Korea in the north to Fujian, China in the south. It has also been introduced to Europe and North America, where it is considered an invasive species.
Cancer (♋︎) is the fourth astrological sign in the Zodiac, originating from the constellation of Cancer. It spans from 90° to 120° celestial longitude. Under the tropical zodiac, the Sun transits this area between approximately June 20 and July 22, and under the sidereal zodiac, the Sun transits this area between approximately July 21 and August 9.
Synapse is a component-based development environment for neural networks and adaptive systems. Created by Peltarion, Synapse allows data mining, statistical analysis, visualization, preprocessing, design and training of neural networks and adaptive systems and the deployment of them. It utilizes a plug-in based architecture making it a general platform for signal processing. The first version of the product was released in May 2006.
A synapse is a neural junction used for communication between neurons
In the military of classical antiquity, a clipeus was a large shield worn by the Greek hoplites and Romans as a piece of defensive armor, which they carried upon the arm, to protect them from the blows of their enemies. It was round in shape and in the middle was a bolt of iron, or of some other metal, with a sharp point. The clipeus was more-or-less identical to the earlier aspis.
Polybius was an ancient Greek historian.
Hematodinium perezi is an internal dinoflagellate parasite that infects crustaceans, including blue crabs, and causes bitter crab disease. Other crustaceans that have been observed to be infected include the Norway Lobster and King Crab, and has been observed to have a significant impact on crustacean fisheries. Infected crabs frequently show signs of weakness and lethargy, and often die due to stress-related handling from fishing as well as metabolic exhaustion due to reduced feeding. H. perezi is a type species of the genus Hematodinium, and perezi has only recently been identified as the specific parasitic dinoflagellate infecting crustaceans. In the east coast of the United States, the disease is most prevalent in the autumn months when the H. Perezi species blooms off the Mid-Atlantic coast. Infected crabs have been observed to have mortality rates as high as 86 percent after only a few weeks, and infection is found to be more prevalent in higher salinity waters towards the mouth of the bay where Callinectes go to spawn, generally 12 PSU and up.

Brooke Christa Shields is an American actress and model. She was initially a child model and gained critical acclaim at age 12 for her leading role in Louis Malle's film Pretty Baby (1978), in which she played a child prostitute in New Orleans at the beginning of the 20th century. Shields garnered widespread notoriety in the role, and she continued to model into her late teenage years and starred in several dramas in the 1980s, including The Blue Lagoon (1980), and Franco Zeffirelli's Endless Love (1981).
Atelecyclidae is a family of crabs belonging to the superfamily Cancroidea, and currently contains eight genera of which two are extinct. However, the genera other than Atelecyclus and Pseudocorystes do not belong in the Cancroidea, and are to be removed from the family.
The term Crab Bowl may refer to either:
Hematodinium is a genus of dinoflagellates. Species in this genus, such as Hematodinium perezi, the type species, are internal parasites of the hemolymph of crustaceans such as the Atlantic blue crab and Norway lobster. Species in the genus are economically damaging to commercial crab fisheries, including causing bitter crab disease in the large Tanner or snow crab fisheries of the Bering Sea.
Pugettia producta, known as the northern kelp crab or shield-backed kelp crab, is a species of crab in the family Epialtidae.
Crab traps are used to bait, lure, and catch crabs for commercial or recreational use. Crabbing or crab fishing is the recreational hobby and commercial occupation of fishing for crabs. Different types of traps are used depending on the type of crab being fished for, geographic location, and personal preference.
