Protoperidinium grande

A large species similar to P. divergens group. Average length is 150-200µ. It is oceanic in warm temperate to tropical waters. Found in seas throughout the world. The photo on the left is as it was seen in the settling chamber only with a lot of other material around it. It was cleaned up in Adobe Photoshop. It was not until it was isolated that identification could be made. It was rotated in all directions to see the variety of ways it could be seen and possibly mis-identified. The photo below is an antapical view from a different sample but exemplifies yet another position the cell can be found. The sample was collected from the fore reef off Carrie Bow Cay in 2003.
