The bar chart above illustrates the numbers of seals, whales, and dolphins recorded in Gormez Strait from 2006 to 2018.
In the bar charts, in 2006, seals had the largest number, approximately 45 seals, the number of whales was recorded at 25, and dolphins at 15. However, in 2010, the seal population experienced a decline, and it was recorded that there were only 25, while the whale population was 27, and the dolphin population increased to 20.
After 4 years, the seal population has increased, although not as many as in 2006. In 2014, there were 35 seals recorded. However, the whale population began to decline to 20, while the dolphin population showed a significant increase to 30.
At its peak in 2018, the number of seal populations increased again and was at 47, while the number of whale populations increased less significantly, only to 27. Meanwhile, dolphins experienced the highest population increase at 52. These animals are recorded every 4 years, but the animals that always show an increase in numbers are dolphins, although in 2006 there were only 15, but after 12 years, the dolphin population increased by 37. Meanwhile, the whale population was only 27, so whales are only half the number of dolphins, and there are 47 seals. So the largest population in the Gormez Strait is dolphins.
