Distribution, Habitat type, Critical habitats, Limiting factors. The most
favourable conditions for the development of this species occur in Black Sea coastal
surface waters during spring, summer and autumn, at water temperatures of 14-23°C.
During the same seasons it can also be found in the open sea although in lower
numbers. The strong eutrophication of the coastal zone and the ctenophore
Mnemiopsis leidyi are limiting factors. The first is a form of contamination and the
second a predator.
