Description
Adults are typically 30–50 millimetres (1.2–2.0 in) long, although individuals up to 90 mm (3.5 in) 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, and shares the family's characteristic sub-chelate first pereiopods (where the movable finger closes onto a short projection, rather than a similarly sized fixed finger) and short rostrum.

Famous quotes containing the word description:
“Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.”
—Ralph Waldo Emerson (1803–1882)
“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (1743–1826)
“The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.”
—Freda Adler (b. 1934)
