The above graph illustrates the population of three marine creatures in the Gomez Straits- seals, whales, and dolphins recorded on an average of every four years.
We observe that the population of whales has fluctuated much less in comparison to the remaining two. The population of seals, however, earlier, showed a decline till 2010 but later picked up in 2014. A key feature that can be seen is the stark increase in the number of dolphins across these 12 years.
In the year 2006, out of the three, seals dominated their counterparts, whales, and dolphins, by 50% and 40% respectively by surpassing the 40 mark. In the year 2010, the average population of all these three creatures collectively seems to have hit an all-time low. Here, the whales and dolphins seem to have shot up in numbers in contrast to the seals.
In 2014, the seals and dolphins both expanded their population, although the rate of increase in seals plummetted faster than that of the dolphins by exceeding 30 in number. Ultimately in 2018, the dolphins are at their highest peak with their average exceeding 50. Meanwhile, the groups of seals and whales also showed an expansion in their size, with whales almost hitting the 30 mark and seals reaching almost 45.
