An apex is the highest point or the top of something, either physically or in terms of importance or success.
From Latin "apex" meaning "summit" or "tip," originally used for the pointed tip of something. Over time it became a metaphor for the top point in rank, power, or development.
“Apex predator” doesn’t just mean big and scary; it means nothing regularly hunts it in its ecosystem. The word hides a whole food web behind that one short label.
