By Michelle Collier, RCDD. Fiber optic cable provides a low loss medium for high-speed communications. While. the continuous fiber cable itself is low loss, terminations at each access point provide a. potential Achilles heel. The biggest cause of signal loss across fiber optic connectors is. contamination.
The blue crab's scientific name, Callinectes sapidus, is from Latin and Greek: calli, beautiful; nectes, swimmer; and sapidus, savory-beautiful, savory swimmer. Like insects, blue crabs have stalked compound eyes and can see in almost every direction at once.
Description. Crabs are crustaceans with five pairs of legs. The first pair is modified as pinchers and the last four pairs are walking legs. The blue crab's carapace (or shell) is about 7 inches (17.8 cm) wide and 4 inches (10.2 cm) long. It weighs 1 to 2 pounds (0.45 to 0.9 kg) when fully grown. The back of the blue crab is dark or brownish green and is drawn out on each side into a large spine.
