BEST CHEAP THRILL FOR KIDS

Experienced anglers know to check them for live baits, but the public is generally unaware that in clumps of yellow-brown seaweed exist miniature aquariums waiting to be unveiled. Sargassum floats (thanks to spherical growths full of carbon dioxide) on the ocean currents. Early summer, when the water is calm and the sargassum gently drifts in, is the perfect time to show youngsters the marvelous bounty of the sea. Grab a clump of weed off the surface (sunken or dark brown weed is too old) and shake it over a bucket of ocean water. Like jewels from a pouch, out spills a variety of tiny creatures: juvenile versions of bigger fish that use the weed as a nursery. Crabs, shrimp, sea horses, nudibranch (called sea slugs), and other adult creatures also inhabit the weed. The most interesting resident is the sargassumfish, which looks exactly like a piece of weed until it flops away as you draw near. Sargassum's many wonders should keep the children occupied until their skin turns red and they volunteer to call it a day.
