Top predators, also called apex predators, occupy the highest trophic level in their ecosystems. They feed on other predators or herbivores and typically have few or no natural enemies as adults. By controlling the abundance and behavior of prey species, top predators influence community structure, energy flow, and ecosystem function, and their presence can trigger trophic cascades that extend through multiple ecological levels.

Terrestrial apex predators include large carnivores such as wolves, lions, tigers, leopards, bears, and crocodilians. In marine environments, apex predators include species such as certain sharks and orcas. These animals often require large territories, have specialized hunting strategies, and exhibit adaptations such as keen senses, powerful jaws or claws, speed, endurance, and sometimes cooperative or pack-based hunting.

Ecological roles of top predators are diverse. They help prevent overgrazing by herbivores, maintain biodiversity, and influence the spatial distribution of prey, which can affect vegetation structure and habitat complexity. In marine systems, apex predators help balance fish populations and coral reef communities. Their activities can indirectly shape the composition and functioning of ecosystems over long time scales.

Threats to top predators stem from human activity, including habitat fragmentation, prey depletion, hunting and persecution, pollution, and climate change. Conservation approaches focus on habitat protection, maintaining prey populations, reducing human-wildlife conflict, and creating ecological connectivity through protected areas and wildlife corridors. When stable, top predators often contribute to resilient and productive ecosystems.
