Seriously weird: Sargassum fish

We’ve got a new critter at the Aquarium, and it’s called the sargassum fish. Funny name, funny looks, funny behaviour! You can come and see just how weird this finned wonder really is during the school holidays (25 June to 17 July), when we’ll be getting into all fish Weird, Wild and Wonderful.

According to the Encyclopedia of Life, “The sargassum fish Histrio histrio is a member of the frogfish family, a group of small, globular fishes with stalked, grasping, limb-like pectoral fins with small gill openings behind the base, a trapdoor-like mouth high on the head, and a ‘fishing lure’ (formed by the first dorsal spine) on the snout.

“The sargassum fish occurs worldwide in tropical and warm-temperate waters. It typically lives in open waters in close association with floating sargassum weed, but is frequently blown into near-shore and bay waters during storms.

Not content with just swimming (which it can do at quite a speed), the sargassum fish “often crawls through the sargassum weed, using its pectoral fins like arms.”

Weird!
