The bar chart below shows numbers of seals, whales and dolphins recorded in the Gormez Straits from 2006 to 2018. Summarise the information by selecting and reporting the main features and make comparisons where relevant.

Write at least 150 words.

The given bar graph portrays population of three different sea mammals in the Gormez straits between 2006 and 2018.

It is clear that the population of all three aquatic animals which includes seals, whales and dolphins increased between the years, despite some fluctuations in between.

As seen in the chart, in 2006, the most populated sea animal in the Gormez straits was seals. From its peak number of 43, the number fell surprisingly to almost 25 in 2010. However, between these two years, the population of whales and dolphins saw a slight incline. While in case of whales, this growth was from 23 to 26, it was from 17 to 22 in case of dolphins.

When both the seal and dolphin population swelled consistently between 2010 and 2018, the growth of the whale population was erratic. During this eight-year period, the number of seals went up from 25 to 44; the volume of dolphins grew more sharply and that was from 22 to 52. Despite a drop  in 2014 (by four whales), the total whale population in the Gormez Straits also went up to 28 in 2018.
