The Mysterious World The term apex predator has existed since at least the early 1970s, when they were discussed in reports about marine life as something distinct from ordinary predators. But, why not just call them predators or top predators and be done with it? Like actual apex predators have a certain role in nature, the word itself occupies a particular linguistic niche. In this context, apex means something close to a summit or peak. This makes more sense if you visualize an ecosystem as a pyramid that sorts organisms into a tiered system. In this theoretical pyramid, each tier contains a grouping of animals that eats the animals in the tier below them. Within the constraints of this model, the apex predator would be at the very top. Able to eat other organisms, but never eaten itself. Examples of apex predator Apex predators are usually associated with large physical size, low densities, and generally large home ranges and movements. Andrés Ordiz, Richard Bischof, Jon E. Swenson, “Saving large carnivores, but losing the apex predator?” Biological Conservation, October, 2013 Large “hypercarnivorous” felids are recognized for their role as apex predators and hence as key elements in food webs and ecosystem functioning through competition and depredation. José Hernán Sarasola, Juan Ignacio Zanón-Martínez, Andrea Silvina Costán, and William J. Ripple, “Hypercarnivorous apex predator could provide ecosystem services by dispersing seeds,” Scientific Reports, January, 2016 The sad part is that some of these apex predators are in decline, sometimes jeopardising ecosystems on which they and other species rely.

The phrase is typically referenced in scientific literature and news articles since it’s fairly technical language. Much of this discussion revolves around concerns about the environment. A common line of inquiry is how apex predators affect their environment and vice versa. Apex predators have a very important role in some ecosystems. Because they’re never preyed upon, they have a role in maintaining the populations of the other organisms in their domain. Other predators and their prey might have an unbalanced dynamic where only the predator may remove some prey animals from the population. Certain prey animals, such as deer, might also run rampant without an apex predator to regulate their population. They are a keystone species: without them, the whole system would collapse. Another popular topic of debate is whether or not humans would be considered apex predators, since as a species, we have been effectively removed from the natural order of the food chain. There hasn’t been a conclusive answer yet. Other uses of apex predator include references by analogy. Human beings are often compared to apex predators, usually for the sake of showing dominance over other people or over other species (like when humans hunt other so-called apex predators for sport).
