Those are krill.

Small, hatchling to infant sea turtles are the main marine organisms that consume sargassum.

Microscopic organisms like protists, algae, and other bacteria are known to consume bacteria in the ocean. Additionally, certain animals like zooplankton, copepods, and some types of fish feed on bacteria as well.
Zooplankton are small animals that primary feed on phytoplankton, which are tiny plant-like organisms found in the water. They may also consume other zooplankton, organic particles, and detritus as food sources. This makes them an important link in the marine food web, providing energy to a wide variety of marine organisms.
Ammonites were marine animals that likely fed on small fish, plankton, and other small marine creatures. The shape of their jaws and radula suggest a diet of soft-bodied organisms.
There are many different animals that kill and consume young, sick, or small animals. These kinds of animals are called predators.
Penguins primarily feed on fish, krill, and other small marine organisms rather than phytoplankton. However, phytoplankton forms the base of the marine food web, supporting the small fish and krill that penguins consume. In essence, while penguins don’t eat phytoplankton directly, they rely on the animals that do, making it a crucial part of their food chain.
Microplankton, which includes small protozoa and tiny marine animals, are among the organisms that consume microplastics. Some larger marine species, such as filter feeders like mussels and oysters, also ingest microplastics while feeding on plankton. Additionally, certain bacteria and fungi can break down microplastics, contributing to their degradation in the environment. However, the ingestion of microplastics can have harmful effects on these organisms.
No, a little auk is not a primary consumer; it is a secondary consumer. Little auks primarily feed on small marine organisms like krill and copepods, which are primary consumers that feed on phytoplankton. As they consume these small animals, little auks occupy a higher trophic level in the food chain.
Various marine organisms eat dinoflagellates, including zooplankton, small fish, mollusks, and some species of whales. Some microscopic predators like ciliates and amoebas also feed on dinoflagellates. Additionally, some herbivorous marine animals, such as certain sea slugs and copepods, consume dinoflagellates as part of their diet.
Moon jellyfish mainly feed on zooplankton, small fish larvae, and other small marine organisms that they catch using their stinging tentacles. They primarily consume plankton and small particles that they filter from the water.
