Image Of the Day caption:
Bluefin tuna are the largest of all tuna speciesadults can reach ten feet in length and weigh more than a thousand pounds. But they start out small, as 2- to 3-millimeter-long larvae. This one was caught by MIT-WHOI Joint Program graduate student Chrissy Hernandez in the Slope Sea, a region of the Atlantic Ocean between the between the U.S. continental shelf and the Gulf Stream farther offshore. The area is a newly-recognized spawning ground for western Atlantic bluefin tunamore good news for a species whose population in the Gulf of Mexico is sustainably managed with a limited harvest.
Caption from Oceanus online:
Bluefin tuna larvae are 2 to 3 millimeters long when they hatch, but they can grow quickly, adding roughly 0.5 millimeter per day. This larva was caught by Chrissy Hernandez, a graduate student in the MIT-WHOI Joint Program in Oceanography, in the Slope Seaa recently discovered spawning area for bluefin tuna. Hernandez estimated it was at least 10 days old.
