Odontella Diatoms

Odontella Diatoms

Most diatoms are free-living, planktonic species, but some live in extensive colonies or linked into tiny chains, like many members of the genus Odontella. These organisms frequently feature long spines on their frustules and may stay connected to one another after cell division via a crossing of the spines. Other items that may be exhibited on diatom frustules include intricate patterns composed of ridges, round perforations, linear markings, ribs, and vertical canals. The beauty of diatom designs has earned them the well-deserved title “jewels of the sea.”
