In late March, we brought you news of Birch Aquarium at Scripps' hatching of 250 tiny Wolf-eels. The Aquarium has just released stunning close-up images of the remaining eggs. The pictures, taken by Peter Kragh, show the eels at the very moment of birth. Adult Wolf-eels are generally curious and friendly, despite measuring 80 inches or more when fully grown.
