Without dolphins, the animals they prey on would increase in number, and their predators wouldn’t have as much to eat. This would disrupt the natural balance in the food chain and could negatively affect other wildlife and the health of the ocean environment.
How would you describe an ecological niche?
A species’ ecological niche can be defined as the range of resources and conditions allowing the species to maintain a viable population. Theoretically, if two species have the same niche, one species will exclude the other.

top predator
They fill an important niche as a top predator and may help to keep populations of marine mammals in balance. Since they are positioned at the top of the food chain, they are never abundant.

The worldwide population of common bottlenose dolphins is about 600,000. Indo-Pacific bottlenose dolphins are abundant, but the overall population is unknown. Chromosome banding techniques have proven useful in bottlenose dolphin population studies.

Examples of Ecological Niches
- Kirtland’s Warbler. Kirtland’s warbler is a rare bird that lives in small areas in Michigan’s northern Lower and Upper Peninsulas.
- Dung Beetle. As the name implies, dung beetles eat dung, both as adults and as larvae.
- Xerophytic Plants.
- Extremophiles.
What is a niche give one example?
The role that a species plays is called its ecological niche. A niche includes more than what an organism eats or where it lives. For example, a garden spider is a predator that hunts for prey among plants, while an oak tree grows to dominate a forest canopy, turning sunlight into food.

Finally, in 1969, a pygmy killer whale was killed off the coast of St. Vincent and a group of individuals was recorded in the Indian Ocean. Necropsy of two pygmy killer whales. Like other oceanic dolphins, pygmy killer whales use echolocation. The centroid of echolocation frequencies is between 70–85 kHz and can range from 32 to 100 kHz.
Are pygmy killer whales bycatch in Sri Lanka?
Pygmy killer whales have been incidental bycatch in fishing operations. They represent as much as 4% of the cetacean bycatch in drift gill nets used by commercial fisheries in Sri Lanka. Like other cetaceans, they are hosts to parasitic worms such as cestodes and nematodes.
How rare is a pygmy killer whale?
The population has a tightly connected social structure with affiliations between individuals that can last up to 15 years. Despite the existence of this resident population, sightings of pygmy killer whales around Hawaii are still quite rare; they accounted for less than 1.5% of all cetaceans sighted in a study lasting from 1985 to 2007.
What are the threats to pygmy killer whales?
A constant risk to their already vulnerable numbers, pygmy killer whales face a plethora of human-induced threats. Overfishing has led to a significant shortage of prey species and in Japan, the Caribbean, Indonesia and Sri Lanka, pygmy killer whales are killed in drive hunts.
