Feeding on phytoplankton, zooplankton constitute the second link in the marine food chain and serve as a primary food source for fish larvae and many other marine organisms.

Considered key biological indicators for monitoring marine health and ecological changes, the distribution of zooplankton species varies depending on factors such as water temperature, salinity, and nutrient availability.

Research shows that climate change directly affects both the amount and diversity of zooplankton, disrupting the balance of marine ecosystems.
