Spring is an “eggs-tra” special time of year when many ocean animals are hatched or born. March 29 through April 4, from 11am-3pm, visit Birch Aquarium at Scripps Institution of Oceanography, UC San Diego, for special activities that highlight the wonders of reproduction in the sea. Come face to face with egg-laying marine animals including squids, fishes, and sharks. Create a shark egg craft, listen to stories, and participate in a daily activity throughout the aquarium.
