Care must be taken with identifying this species, even microscopically, as it can be easily confused with the genus Synchelidium, its visual appearance is very similar indeed. Synchelidium species are also likely to occur with Pontocrates altamarinus.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help

people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
