Skeletonemataceae is a family of diatoms in the order Thalassiosirales. There is currently only one known genus in this family of diatoms known as Skeletonema as reported from diatom.org.[1] Being from the Thalassiosirales order means that Skeletonemataceae are centric diatoms.
The sexual reproduction of oogamous is where reproduction occurs by the union of mobile male and immobile female gametes.[2] This way of reproduction is possible due to the lack of significant motility which is also a defining trait of Skeletonema.
