Is Skeletonema costatum Diatom?
Skeletonema costatum (Greville) Cleve is a marine and occasionally brackish, cosmopolitan diatom species mainly found in coastal areas (Castillo et al. 1995). Skeletonema costatum plays an important ecological role, as it forms large-scale algal blooms in eutrophic coastal waters and estuaries (Jiang et al.
Where is Skeletonema costatum found?
Skeletonema costatum is one of the dominant species responsible for red tide outbreaks and blooms frequently occur in the Yangtze River estuary and adjacent waters in China. Of the red tide outbreaks in the Yangtze River estuary between 1972 and 2009, S. costatum occurred during 20% of the 174 recorded outbreaks.

How many types of phytoplankton are there?
There are about 5,000 known species of marine phytoplankton.
What are the four types of plankton?
Trophic groups Phytoplankton (from Greek phyton, or plant), are autotrophic prokaryotic or eukaryotic algae that live near the water surface where there is sufficient light to support photosynthesis. Among the more important groups are the diatoms, cyanobacteria, dinoflagellates and coccolithophores.
What are the 6 size classifications of plankton?
Size groups
| Group | Size range (ESD) |
|---|---|
| Megaplankton | > 20 cm |
| Macroplankton | 2→20 cm |
| Mesoplankton | 0.2→20 mm |
| Microplankton | 20→200 µm |
What is the order of plankton from smallest to largest?
Picoplankton – Organisms 0.2 micrometer to 2 micrometers, e.g., bacteria. Nanoplankton – Organisms 2-20 micrometers, e.g. phytoplankton and small zooplankton. Microplankton – Organisms 20-200 micrometers, e.g., phytoplankton and small zooplankton.
Which plankton is smallest?
Cyanobacteria –
Cyanobacteria – The smallest plankton (< 0.2 µm) blue-green algae are abundant in the oceans and sometimes in freshwater. Their outer membrane is very hard to digest; not many larger plankton eat them until that membrane is destroyed by a few species of bacteria and virus.
What is the scientific name of Skeletonema?
Skeletonema is a genus of diatoms in the family Skeletonemataceae. It is the type genus of its family. The genus Skeletonema was established by R. K. Greville in 1865 for a single species, S. barbadense, found in the Barbados deposit [Jung 2009].
What is the shape of Skeletonema?
Skeletonema belong to the morphological category referred to as centric diatoms. These are classified by having valves with radial symmetry and the cells lack significant motility [Horner 2002]. Skeletonema are cylindrical shaped with a silica frustule.
Is Skeletonema a freshwater species?
Eugene F. Stoermer, Matthew L. Julius, in Freshwater Algae of North America, 2003 Skeletonema is a primarily marine and estuarine genus which has a few representatives in fresh water. The circumscription of freshwater species is difficult.
Where does Skeletonema grow?
Skeletonema grows primarily in marine and estuarine habitats. Species within the genus are known to form large blooms in eutrophic and saline inland lakes and large rivers. Specimens of Skeletonema are often overlooked.
