Whopping Fish Declared New Species

A man-sized grouper that trolls the tropical waters of the Eastern Pacific Ocean for octopuses and crabs has been identified as a new fish species after genetic tests.

Called the goliath grouper, the fish can grow to six feet (1.8 meters) in length and weigh a whopping 1,000 pounds (454 kg). Until now, scientists had grouped this species with an identical looking fish (also called the goliath grouper, or Epinephelus itajara) living in the Atlantic Ocean.

“For more than a century, ichthyologists have thought that Pacific and Atlantic goliath grouper were the same species,” said lead researcher Matthew Craig of the Hawaii Institute of Marine Biology, “and the argument was settled before the widespread use of genetic techniques.”

Once upon a time, about 3.5 million years ago — before the Caribbean and the Pacific were separated by present-day Panama — they were, in fact, the same species. Now, DNA tests have revealed the two populations have distinct genes, indicating they likely evolved into two separate species after their ocean homes were divided by Central America. …

The new Pacific species, now designated as Epinephelus quinquefasciatus, is described in a recent issue of the journal Endangered Species Research.

The Atlantic variety, E. itajara, is currently listed as critically endangered by the IUCN, or International Union for Conservation of Nature. Due to its scarcity, E. quinquefasciatus also may be considered critically endangered.
