Acanthocystis. Colored scanning electron micrograph (SEM) of a centrohelid heliozoan with tangential plate-scales and radial spines. This genus Acanthocystis contains unicellular, free-floating planktonic or benthonic living organisms which are common in freshwater but also found more rarely in marine habitats. The evolutionary position of the centrohelids is not clear. Magnification: x 2500, when printed 10 centimeters wide.Acanthocystis.

Great Hammerhead Shark (Sphyrna mokarran). This 3 meter long female has an algae covered casey tag (also called the National Marine Fisheries Service 'M tag') at the base of the dorsal fin, previously attached by scientists from the Bimini Biological Field Station (aka the Sharklab) in the Bahamas. Inside the tag is an identifying number and instructions requesting any fishermen who catch this animal to report its position and condition to the NMFS.Great Hammerhead Shark (Sphyrna mokarran).
