Filter feeders are animals that feed by straining suspended matter and food particles from water, typically passing the water over a specialized filtering structure.
Blue whales feed almost exclusively on krill(tiny crustaceans/fry of fish),i.e, they are filter feeders.
However, humans also hunt them for meat and other body parts (commercial use).
Therefore, Blue Whales have been categorized by IUCN as “endangered” species.
Blue Whales are filter feeders and do not eat humans; instead, they feed upon krill.
