Snorklers and marine aquarium lovers are familiar with lookdowns, a silvery, round fish with a blunt forehead that reaches a weight of about two pounds. The name comes from the lookdowns countenance, which is reminiscent of a snobbish or disapproving human expression. They live in warm waters of the Western Atlantic and are common from Chesapeake Bay to Uruguay, and there is an outpost population off Bermuda. Stray lookdowns have been sighted as far north as the Gulf of Maine and Nova Scotia. Lookdowns like shallow, coastal waters with sandy or hard bottoms and are usually found in schools feeding on small fish, crabs, worms, and shrimp. They are prey to larger fish, some artisanal fishermen and aquarium collectors.
