Skeletonema japonicum; Scientific classification Together with S. pseudocostatum, S. tropicum, and S. grethae, it possesses external processes of its fultoportulae that have narrow tips which connect with those of sibling cells via fork-, knot-, or knuckle-like unions. Skeletonema is a genus of diatoms in the family Skeletonemataceae. /AQUATIC SPECIES/ Skeletonema costatum, Thalassiosira pseudonana, Glenodinium halli, and Isochrysis galbana were used to study the effects of chlorinated and brominated compounds on cell division. For industrial processes and water systems, antifoulant coatings and paints, wood preservatives, and aquatic areas, Tier II (dose response) studies are required on four species (Anabaena flos-aquae, Navicula pelliculosa, Skeletonema costatum, and Selenastrum capricornutum). The metabolism of (14)C-labeled rimsulfuron was studied in male and female rats.
