Endangered Dolphins – How It Started

Dolphins are perhaps the most lovable creatures among the Cetaceans (includes whales and porpoises) and among aquatic animals in general. They have been known to easily form bonds with others of those of their kinds and with humans they come in close contact to as well. Sadly, these dolphins have become endangered over the years. It would be best to know the reasons why, how, and what are those particular species that are easily regarded as endangered dolphins.

The impacts of humans on the environment are mainly responsible for endangering this very popular and beautiful mammal. This is attributed to various toxic elements, trash, wastes, and other byproducts spread into the ocean’s waters. Not only that, even the more unintentional incidents such as pesticides from accidental collisions by boat propellers are also culprits for the reasons why dolphins have become endangered and steadily declining in numbers.

Another harmful factor to the dolphin’ endangerment is careless human byproducts spewed out into the ocean. The dolphins also frequently fall victim to the fishermen’s nets. Studies show that the populations of dolphins have a steady decline of 10% every year. One of the main causes is also pollution in their living environment. Dolphins also oftentimes fall into human traps designed to catch them. Some people consider this their form of recreation and one of their hobbies. Dolphins are taken to wildlife parks to be shown as a recreation entertainment. This is why they are losing their proper environment and eventually, perish.

Most recently, dolphins are hunted and killed in large numbers for commercial purposes. The meat is found to be flavorful and is a favorite to humans. One phenomenon that’s particularly disturbing is the mass hunting of dolphins in countries like Japan wherein the meat is traded out to westerners. Atomic bomb testing in sea water in recent years has also created a hostile environment for these endangered dolphins.

The species falling under the group of endangered dolphins include the Irrawaddy dolphin which is the euryhaline species of the Oceanic dolphin found in discontinuous sub-populations near sea coasts and in estuaries and rivers in parts of the Bay of Bengal and Southeast Asia. Another one is Hector’s dolphin which is the best known of the four dolphins in the genus Cephalorhynchus and is found only in New Zealand. At about 1.4 meters in length, it is one of the smallest of the Cetaceans.

Another endangered dolphin is the Amazon river dolphin, alternately Bufeo, Bofeo Colorado, Boto, Boto Cor de Rosa, Boutu, Nay, Tonina, or Pink River Dolphin. It is a freshwater river dolphin endemic to the Orinoco, Amazon, Araguaia/Tocantins river systems of Brazil, Bolivia, Peru, Ecuador, Colombia and Venezuela.

Irregardless of the genus or species, an increased awareness in preservation on these beloved mammals will we be able to take care of this distressing issue and will we eventually save and preserve these endangered dolphins.
