Sun's early rays spilling over her shoulder, notes spilling from her pen, Dr. Clark records data from a dive off El Kura, a barren hook in the Gulf of Aqaba (below). Associate professor of zoology at the University of Maryland, she has studied garden eels for three summers. Of the world's dozen known garden eel species, only one, Gorgasia sillneri, has thus far been found in the Red Sea. It abounds there where sand is loose, food plentiful, and enemies few.
