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