In a new study published in the Endangered Species Research, it was found a new population of Whale whose sound differs from other species. They were found to be peacefully swimming in the waters of the Indian Ocean. The team has confirmed this after a thorough comparison with other Whale sounds. The sound was picked at three different underwater locations located 3500 km apart in the ocean. First near the coast of Madagascar which is the largest island in the Indian Ocean followed by the Western Arabian sea near the coast of Oman and lastly in the Chagos Archipelago in the Central Indian Ocean. Previously, it was thought that these waters harbor only single species of Blue Whale (Balaenoptera Musculus), but these new sounds didn’t match up to their calls. Therefore, this led scientists to believe at least there two species of Blue whales are existing in these widespread waters. Although we need visual or genetic data to confirm the existence of a new species, scientists know for sure that these sounds have not been previously recorded.
Scientists say that the sound is like any other Blue Whale with lower frequency, regularly spaced repetition of single phrases but still has many unique features. Further research and studies can throw us more light on finding these amazing new creatures pretty soon. To accomplish this, underwater microphones are needed to be placed in the Indian Oceans, which will also help us to know the true distribution and range of these large gentle giants.
While we talk a lot about Blue Whales, which is thought to be the largest mammal ever existed, we should also focus more on the conservative status of these individuals. Five decades earlier, these gentle giants were mercilessly hunted to the brink of extinction until the International Whale Commission banned this practice. Even in the 1960s, the Soviet Union took part in the intensive killing of at least 1294 whales, and they speculate this unheard population might be the ones they would have targeted. Due to these hunting practices, their population would have restricted to a fewer number of individuals even now, which addresses the need for protecting these ocean giants who te us more tales of the oceans.
