Amphisolenia quadrispina (Kofoid)
This is a most unusual species of dinoflagellate. Its body is very elongated with an epitheca reduced to cap-like plates. (Dodge) It's length is 600-700µ. The base of the cell, to your right, has four spinules. They look like little feet or stalks. The neck, to your left, expands to two collars with the end of the cell protruding through the collars. This is a tropical and subtropical species in both the Atlantic and Pacific oceans, the Mediterranean and the Indian Ocean. This photo was taken in two sections and was artfully put together by Dr. Charles Gallegos. Our apologies if it took a long time to load. It's a large photo so you can see the ends a little better.
