TRUE: Electric eels are actually fish that breathe by gulping air from the surface.
TRUE: Some fish start their lives as males but grow into females.
FALSE: Despite their unusual shape, sunfish are some of the sea’s strongest swimmers

Sunfish, or molas, do not have a swim bladder and steer themselves by squirting a jet of water out of their mouth or gills. For this reason, sunfish maneuver poorly and are not strong swimmers. Have you ever seen a sunfish before? Where did you see it? And who’s surprised to learn that electric eels aren’t actually eels?
