The provided chart illustrates the figures for three marine species, i.e., seals, whales, and dolphins, inhabiting the Gormez Straits between 2006 and 2018.
Overall, it is evident that there was an upward trend among all these three marine animals in this period, and the seal population remained generally the highest throughout the years, being overtaken by dolphins only in 2018.
In 2006, the seal population exceeded 40 members in 2006, which was nearly double that of whales, while the number of dolphins stood at approximately 17 units. Moreover, the quantity of whales was stable in the later years, with an average statistic of around 25. On the other hand, the dolphin population saw a steady and fast-growing rise. While there was a dramatic decline in the number of seals in 2010, plummeting to 25 units, as compared to 2006, this species surged again in the following years, reaching 35 in 2014 and then 45 in 2018.
By the last year of this period, the amounts present of both seals and dolphins had already trumped the figure of whales by a significant degree, with the dolphins climbing above the 50 mark.
