The bar chart below shows numbers of seals, whales and dolphins recorded in the Gormez Straits from 2006 to 2018.

The diagram indicates the number of three various types of fish including seals,

whales

and dolphins documented during a 12-year interval up to 2018 in Gormez Straits.

Overall

,

it is clear that

the population of dolphins has boosted within the period;

whereas

the data of

whales

were almost steady. Regarding dolphins and

whales

, it can be seen that at the start of the investigation, the figures of

this

creature were the least one in the whole of the scheme. Meanwhile, since 2010,

this

parameter surged to more than 50 in 2018, to be the peak of the chart.

On the other hand

,

whales

had no significant growth in their community. They were counted around 25 in 2006, but their information experienced a series of fluctuations and eventually, with negligible progress, they became roughly 28 in 2018. With regard to seals, what stands out from the illustration is that, at the beginning, they had by far the greatest society;

while

in contrast

, its figure levelled off to 25 in 2010.

Subsequently

,
