The animal on the cover of Getting Started with Flex™4 is a sea urchin. The name is generic—“urcheon” is MiddleEnglish for “hedgehog”—and covers members of the taxonomic classEchinoidea. Sea urchins can be found in every ocean andin a wide range of colors, including black, green, brown, purple, and red.Specimens are typically small, only growing to 1–4 inches across, thoughsome extraordinary urchins have been found measuring 14 inchesacross.
Sea urchins possess fivefold symmetry, similar to sand dollars and seastars, though it is often not immediately apparent in living individuals.Their shells, called tests, are round and spiny, and their small tube feetallow them to move slowly along surfaces, gathering food into theirdownward-facing mouths. Sea urchins eat mostly algae, but will sometimesalso eat various invertebrates such as mussels and sponges. Reproductionoccurs externally; both sperm and eggs are released into the sea water,where fertilization occurs. A fertilized sea urchin egg can develop into afree-swimming embryo in as little as 12 hours, though it may take severalmonths for the individual to develop from that stage to its adultform.
The ovaries of a sea urchin, called corals or roe, are considered adelicacy in many parts of the world. Though prepared differently and fromdifferent species, sea urchin are eaten in theMediterranean, Chile, the West Indies, New Zealand, the Pacific coast of North America, and Japan, forexample. The demand for sea urchin is particularly high in Japan, wherehigh-quality uni, as it is called, can sell for as muchas $450/kg.
