picture info	Crangon Crangon ''Crangon crangon'' is a species of caridean shrimp found across the northeastern Atlantic Ocean from the White Sea in the north of Russia to the coast of Morocco, including the Baltic Sea, as well as occurring throughout the Mediterranean and Black Seas. It is commercially important and fished mainly in the southern North Sea. Its common names include brown shrimp, common shrimp, bay shrimp, and sand shrimp, while translation of its French name ' (or its Dutch equivalent ') sometimes leads to the English version grey shrimp. Description Adults are typically long, although individuals up to have been recorded. The animals have cryptic colouration, being a sandy brown colour, which can be changed to match the environment. They live in shallow water, which can also be slightly brackish, and feed nocturnally. During the day, they remain buried in the sand to escape predatory birds and fish, with only their antennae protruding. ''Crangon'' is classified in the family Crangonidae, ...

picture info	Fossil Record A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils.

	Crangon Franciscorum ''Crangon franciscorum'' is a species of shrimp in the family Crangonidae which is endemic to the brackish estuaries of California, and found from Puget Sound in the north to San Diego, California in the south. The species is especially abundant in San Francisco Bay, despite population fluctuations due to environmental stresses. Its common names include bay shrimp, sand shrimp, common shrimp, grass shrimp, black shrimp, California shrimp and black tailed shrimp. The species has been commercially fished from 1869 to the present. Role in the Bay food web This shrimp species is "an important part of the estuarine food web" in the greater San Francisco Bay. It feeds on bivalves, amphipods and foraminiferins, and is prey for various fish, including striped bass, white sturgeon, Pacific tomcod and shellfish such as Dungeness crab. Its diet is "heavily influenced by predator size, temperature-salinity preferences, and prey availability." Lifecycle The shrimp are short-lived, wi ...
