1T big fish dismembered in Zhejiang   2012-09-04 00:00:00

  A 1-tonnage and 8-meter manta ray is captured and dismembered in Taizhou, Zhejiang province on September 3.

  The genus Manta contains two species of manta rays: the Reef Manta Ray (Manta alfredi) and the Giant Oceanic Manta Ray (Manta birostris),which are the largest species of the rays in the family Mobulidae, and the largest rays in the world. Oceanic mantas reach at least 7 metres (23 ft) in width and there are anecdotal reports of even larger specimens, while reef mantas reach about 5.5 metres (18 ft) in width.

  Manta rays are circumglobal and are typically found in tropical and subtropical waters, although oceanic manta rays can be found in temperate waters.Oceanic mantas reside in deep water, pelagic zones, making periodic visits to cleaning stations at seamounts and coastal reefs. Minimal concrete information exists on oceanic manta movements, but they are generally believed to be more transient and migratory than the smaller reef mantas, which tend to be resident to shallower coastal habitats.

Most sharks, rays and skates (Elasmobranchii) have small brain-to-body ratios, but the ratio is relatively high in manta rays and the closely related Mobula rays.
