The official daily recommended intake of iodine currently sits at 150 mcg for adults (7). Quekett's abalone is similar in size and distribution to the spiral-ridged siffie, being slightly larger and occuring a bit further east along the South African coast.

More specifically, it is a gastropod - literally meaning "stomache on a foot". Abalone is a gastropod mollusk that lives in coastal saltwater. It  is very large and can grow up to 23cm across. The outer edge of the foot is called an epipodium, a sensory organ that is covered by a host of tentacles. This influx of rock lobsters, which previously only inhabited the West Coast and rarely rounded the Cape Peninsula, has not been thoroughly explained. One of the standout nutrients in abalone is selenium. That said, research suggests there are some areas of the world where heavy metal contamination might be more of a concern. Image courtesy, All abalone, including this northern abalone, use their barbed tongues or "radula" to scrape apart algae for consumption. Abalone is weird! Thanks in advance. The gill chamber, a part of the body near these holes, is used to eject all of the abalone's waste into the water. Among these nutrients, abalone’s supply of iodine—which can be hard to find in food—is particularly useful.
