Whales are the enormous animals, with some species ranking amoung the world’s largest. For example, a Blue Whale can grow up to 30 m in length and their has never been an animal larger than a Blue Whale. There is a fun fact about them that they are also Yellow Blue Whales appear blue under water, but on land they are a modelled blue grey colour with yellow bellies. A Whale can weight as much as 40 elephants, larger than dinosaur.
Whale species have been split into two main categories. The first are toothed whales, which have teeth as the name implies. Seals, squids, and fish are amoung prey of these whales. Baleen whales, on othere hand, have brush-like fibrous structures in place of teeth, which they use to filter & ingest animals like shrimps and krills Some whale species can live for up to 200 years, and just like humans, they pass on their crucial data to future generations such as breeding locations, migration routes and food availability.

Whales are the world’s longest migratory mammals. Some species of whales travel up to 10,000 Kilometers for breeding and food, which is impossible for other species. Whales carry cultural values. Years of research indicate that they have their own cultural values, similar to humans, dealing with social behaviour to raising their calves, which they will pass on to the next generation. This is a distinct feature. Whales can sing which may seem impossible, but according to investigators, whales can produce variety of sounds and use these sounds to mimic singing. They are said to make these sounds to impress opposite genders.
Every organism serves specific role in nature, however there are certain animals that are essential for survival of others. They are known as keystone species. Whales are keystone species. So, how do whales help to our survival?
1. Whales regulate oceans
Generally, whales go to the bottom of the sea to eat their food, where they can easily find fish and Krill, but since we all know, they have to come out of the sea to breathe, and while doing so, they poops, which is known as faecal plumes. Nutrients such as nitrogen, iron, and phosphorus are abundant in faecal plumes. When faecal plumes reach the surface of the water, microorganisms are born, which serve as a meal for many fish, thereby maintaining the flow of nutrients in the ocean.
2. Whales absorb CO²
Carbon dioxide is produced by everything we do, from manufacturing goods to breathing. As a result, the rate of carbon dioxide in the environment has increased, and whales have absorbed carbon dioxide from the environment. And over the course of their lives, they can absorb up to 33 tonnes of CO2, which is equivalent to the carbon dioxide absorbed by 1500 trees.
3. Whales facilitate planktons.
Whales facilitate many microorganisms, one of which is planktons. Planktons are small microscopic organisms classified into two types: Plants Plankton and Animals Plankton, both of which absorb approximately 37 billion metric tonnes of CO2, the equivalent of 1.7 billion trees. This is due to whales.
But, unfortunately whales are being slaughtered for a variety of reasons.
It is to be said that the count of blue whales in the antarctic was once 225,000. It is shocking to know that now the count is less then 3000. Based on the most recent studies, whales could become extinct in the next 25 years. why are these being hunted?
Humans slaughter whales to make perfumes and mechanic oils, as well as to eat. Nowadays, every part of a whale is used in some way and are being targeted because of their commercial value and the recovery of the whale population is a monumental task in and of itself. Whales can only have one calf every one to three years. That is why the process is slow and longwinded. If whales had not been mass-killed for commercial reasons, they would have been removing 16000 tonnes of carbon dioxide from the environment today, which would have been a great way to combat global warming and climate change.
But, unfortunately, we are still a long way from reality. So, if you believe that we must save whales. Please share this information and educate people about the value of whales. because the sooner we raise awareness, the sooner these species can be saved.
