Silt Silt Silt is granular material of a size between sand and clay, whose mineral origin is quartz and feldspar. Silt may occur as a soil (often mixed with sand or clay) or as sediment mixed in suspension with water (also known as a suspended load) and soil in a body of water such as a river. It may also exist as soil deposited at the bottom of a water body, like mudflows from landslides. Silt has a moderate specific area with a typically non-sticky, plastic feel. Silt usually has a floury feel when dry, and a slippery feel when wet.
Granular pugolovka Granular pugolovka The granular pugolovka ("Benthophilus granulosus") is a species of gobiid fish widespread in the Caspian Sea. It is a small fish, with a length up to TL. It was listed as Least Concern by the IUCN in 2008: there are no known major threats. Granular pugolovkas are very abundant in their habitat due to their size and lack of natural predators. The common name 'pugolovka' is a Ukrainian word for tadpole. "Benthophilus granulosus" has a flat head with a flat barbel on the chin that is often described as being leathery. The body colors depend on the habitat
