Over the entire time period, the population of these marine creatures showed an overall increase, despite some minor variations in between.
In 2006, seals were the most populous sea animals in the Straits, reaching a peak number of 43. Surprisingly, their population dropped to nearly 25 in 2010. Conversely, during this period, both whales and dolphins experienced a slight increase in numbers. Whales went from 23 to 26, while dolphins increased from 17 to 22.
From 2010 to 2018, the seal and dolphin populations consistently grew, whereas the whale population exhibited irregular changes. Over this 9 year period, seals went up from 25 to 44, while dolphins experienced a more significant rise to approximately 52. In 2018, the total number of whales in the Gormez Straits was 28, which was only 6 more than in 2014.
