Misnomers Memes

The ultimate taxonomic bamboozle! Marine biology's greatest naming prank strikes again. Despite their fishy names, cuttlefish (cephalopods), starfish (echinoderms), jellyfish (cnidarians), silverfish (insects), and shellfish (mollusks) aren't actually fish at all—they lack vertebral columns and other fish characteristics. Meanwhile, seahorses, with their weird vertical swimming position and horse-like heads, are legitimate fish with gills, fins, and vertebrae. Nature's like that friend who labels all their kitchen containers incorrectly just to watch you put salt in your coffee.
