New Species of Sea Bass from Curacao Linked to Unusual Fish Larva

 New Species of Sea Bass from Curacao Linked to Unusual Fish Larva

The new species of sea bass from curacao linked to unusual fish larva stages of marine fishes in the open ocean because the young fishes often bear little or no resemblance to the adults. Confronted with a perplexing fish larva collected in the Florida Straits, Smithsonian scientists turned to DNA barcoding, which yielded an unexpected discovery—a match between the mysterious fish larva and adults of a new species of sea bass discovered off the coast of Curacao. The team's research is published in the May 13 issue of PLOS ONE.

Most marine fishes have a pelagic larval stage that drifts in the surface or near-surface currents of the ocean―an environment very different from the one they inhabit as adults. Two different environments often require two different body shapes and appearances, resulting in larvae that look very different from the adults of the same species.

The larva at the center of this study first came to the team's attention from a photograph without identification in another research paper. The scientists recognized it as a member of the sea bass family Serranidae but were intrigued by its seven very elongate dorsal-fin spines.

"This feature isn't known in any Atlantic sea bass larvae, but it is similar to one species of Indo-Pacific sea bass," said David Johnson, a zoologist at Smithsonian's National Museum of Natural History. "We initially thought the larva must have been caught in the Indo-Pacific Ocean, but we were wrong." The fish larva in the photo was in fact caught in the Florida Straits.

The team obtained the preserved larval fish for further study and were met with an immediate mystery—a DNA sequence from the specimen did not match any known fish species. That, along with unique morphological features, led the scientists to begin describing the larva as a new species despite the absence of adults.
