Arthrophycus, and Sargassum. This subgenus classification is based on the morphological characteristics of the seaweed thallus. In addition, the distribution pattern can also be used to distinguish between Sargassum subgenera. The most common subgenera found in subtropical/temperate regions are Bactrophycus and Arthrophycus.Color does help identify some rocks, such as the monochromatic azurite with its deep azure color, but many minerals have combinations or colors or hues caused by the presences of impurities. For example, amethyst is quartz, and it would be clear if it weren't infused with traces of iron.

The nature of the Arthrophycus tracemaker has historically been a matter of debate with two main hypotheses: the Arthrophycus derives from the Greek; specifically, "arthro" means joint or pertaining to the joints, and "phycus" (phŷkos) refers to seaweed or algae. These traces were originally interpreted as the remains of plant matter.
