The given bar chart illustrates the populations of three sea mammals (seals, whales, and dolphins) in the Gormez Straits between 2006 and 2018.
It can be seen that the number of dolphins increased over the given period. The populations of whales and seals stayed relatively stable with minor fluctuations over the same period of time.
In 2006, the number of seals was the highest, at 43 while the population of dolphins was the smallest (17). On the other hand, in 2010, the number of whales was the highest (26). Seal numbers fluctuated dramatically, falling sharply to 25, however the number of dolphins was still the lowest, at 22.
In 2014, the number of seals increased to 35, while the whale population decreased slightly to 22. The dolphin population also continued to rise, reaching 33. By 2018, the number of dolphins had risen sharply to 52, becoming the highest of the three species. Seals also increased, reaching 45, but whales remained the lowest throughout, ending at 28.
