Huge Wolf Eels Spotted in the Salish Sea, Up to Eight Feet Long

Video by diver John Roney from the Salish Sea shows a giant wolf eel—an actual fish that can reach up to eight feet long. Though called eels, wolf eels have pectoral fins behind the head and are not true eels. Adults are gray and rugged, while juveniles appear bright orange with a honeycomb pattern. One observed eel sported a healed mouth wound from an urchin spine, fitting their diet of sea urchins and highlighting the striking size difference between young and adults.

Revised Fish Anatomy Alters Understanding of Vertebrate Skull Evolution

A new study revises the understanding of coelacanth fish anatomy, revealing that many previously thought evolutionary muscle features are actually ligaments, which reshapes our view of vertebrate skull evolution and shows coelacanths are more similar to sharks and tetrapods than previously believed.

"Unraveling the Mystery of the Little Fish's Unbelievable Mouth"

The hingemouth, a small brown fish found in central west Africa, has a truly bizarre feeding apparatus that includes a trunk-like mouth that extends from its forehead to suck up food from the ground. Researchers spent five years investigating this unique mouth structure, which they named the proboscis, and found that it allows the hingemouth to thrive in its swampy habitat by breathing air and feeding on detritus. Despite its extreme anatomical reorganization, the hingemouth proves that evolution can lead to wild diversity beyond conventional notions of success.
