While bottlenose dolphins are not categorized as endangered by the IUCN Red List of Threatened Species, they are undoubtedly at risk from the commercial fishing industry and habitat destruction. While conservation efforts have helped dolphin populations to avoid nearly certain extinction, this trend could change if humans do not remain vigilant about protecting these marine mammals. Currently, scientists estimate that there are tens of thousands of bottlenose dolphins.Continue Reading
While it is illegal to target bottlenose dolphins, many ships end up inadvertently killing them with their nets. Dolphins are frequently caught in commercial fishing nets, causing them to become entangled and drown as they are unable to reach the surface for a breath. The increased amount of boat traffic in the areas frequented by bottlenose dolphins also represents a threat, as the boats may strike and kill the dolphins.
Habitat destruction occurs in many forms, but all present problems for dolphins. Chemicals that are pumped into the ocean may sicken dolphins or their prey, while floating debris may be mistaken for food and swallowed with disastrous consequences. Additionally, global warming may affect the dolphin populations as the temperature of the ocean rises.
Dolphins are very important components of marine ecosystems, and if they were to disappear, the entire food chain would suffer. Dolphins primarily prey on small fish and squid, but they will consume other prey from time to time.Learn more about Zoology
Blue whale hunting is banned by the International Whaling Commission, and the blue whale is listed as endangered by the IUCN Red List of Endangered Species and the U.S. Endangered Species Act as of 2014. Other conservation efforts include monitoring populations by satellite tags and shipboard observers.Full Answer >
The loss of biodiversity in marine environments is attributed to many sources, including human activities such as hunting and commercial fishing, the addition of toxins and chemicals to surrounding waters and loss or degradation of coastal habitats. Many factors contribute to the loss of marine biodiversity, but human activities are among the worst offenders. Commercial fishing, for instance, removes key organisms from the environment, which disrupts the food chain and deprives other organisms of their traditional sources of food.Full Answer >
The Indian Ocean, like many of Earth's oceans, serves as home to a diverse number of species, including anenomefish, Great White sharks, bottlenose dolphins, blue whales, sea turtles, jellyfish, stingrays, sea anemones, sea snakes, worms and stonefish. Creatures inhabiting the Indian Ocean range in size from tiny microorganisms to some of the largest animals on the planet, such as large sharks and blue whales. Some creatures pose little threat to humans and other mammals, while others contain lethal venom or emit potent toxins, potentially causing harm.Full Answer >
Dolphins communicate vocally through a series of high-pitched clicks and whistles. Dolphins are also thought to employ body language, physical communication and a process known as echolocation in order to communicate with each other.Full Answer >
