St. John Marine Life: Parrotfish

Adult Parrotfish

Parrotfish are still plentiful on the reefs around St. John and that’s a good thing. These brightly colored fish are easy to identify because their teeth are tightly packed together and are on the outside of their jawbone giving them a parrot-like beak. It is this feature which enables the parrotfish to scrape algae off the of coral and rocks found on the reef. This process called bioeriosion has important benefits for the coral reef environment.

First, coral needs to have a clean place to grow. Rocks covered by algae would not be suitable for the beginning of new coral structures. Second, coral covered by algae could not survive and third, the scraped off algae passes through the parrotfishes’ digestive system and is excreted as sand, which comprises a good deal of the sand found on St. John beaches. One parrotfish can produce as much as 200 pounds of sand in a year.

Below Average Hurricane Season Predicted
By Lynda Lohr — April 11, 2014

There was good news Thursday from the Colorado State University hurricane prediction team. Researcher Phil Klotzbach said he thinks the upcoming season will see a below average number of storms.

“The tropical Atlantic has anomalously cooled over the past several months, and the chances of a moderate to strong El Niño event this summer and fall appear to be quite high,” Klotzbach said in a press release issued Thursday. “Historical data indicate fewer storms form in these conditions.”

The team expects nine named storms during the Atlantic hurricane season, which runs from June 1 and Nov. 30. Of those nine storms, researchers expect three to become hurricanes and one to reach major hurricane strength with sustained winds of 111 miles per hour or greater…. read more
