Skeletonema marinoi is a diatom. Together with S. dohrnii, this species has flattened extremities of the processes of the fultoportulae, which interlock with those of succeeding valves without forming knuckles.

In 2025, a 7,000 year old strain of S. marinoi was resurrected from a core of anoxic Baltic Sea sediment, with cells that were as viable as its modern descendants.
