Apple #79: Shark Ray


Starting this month, the Newport Aquarium in Newport, Kentucky will open its shark ray exhibit -- the only shark ray on display in the Western Hemisphere.

  • Shark rays are quite rare. They live in the Indo-Pacific oceans, especially in waters around Australia and Taiwan.
  • They are rays, with gills on the underbelly, but with the more powerful body of a shark.
  • They have horn-like ridges on their back, and large spiracles (breathing holes) just behind their eyes.
  • Shark rays do not pose a threat to humans. They use their flat, "pavement-like teeth" to crush and eat crabs and other shellfish.
  • Sweet Pea, pictured above, weighs forty pounds and is about four feet long. Shark rays can grow to be nine feet long.
  • Sweet Pea was caught in a trap in Taiwan and was eventually acquired to live at the aquarium, in hopes of studying and helping to support conservation of this rare species.
  • Shark rays are in a family which also includes guitarfishes. (I'm going to have to find out about those, too, someday.)
