World Penguin Day was commemorated at the end of April. This was created to reflect on its conservation, since it is recorded that, in the last 100 years, its population has declined markedly . Maybe to start to become aware, you should know some interesting things about penguins. The first and most important is that this species of adorable birds that live in the south of our country do not fly, but swim.
Did you know that, throughout their evolution, the wings of the penguins were turned into fins to adapt to aquatic life? And that now, once in the water, can you advance at speeds of up to 36 kilometers per hour?
And there is much more you probably didn't know, that's why we share a “top ten” of interesting facts .
1. It is believed that the terminology “penguin” comes from two Welsh words meaning “head” and “white” (although penguins do not have white heads).
2. They live in large colonies of hundreds or even thousands of individuals. In Argentina there are approximately 56 and Chubut has three colonies suitable for conservation and public opening: Cabo Dos Bahías, San Lorenzo and Punta Tombo.
3. 17 of the 18 species of penguins that exist are found in the southern hemisphere .
4. Its natural camouflage works as a protection against predators. Their black spine makes them less visible to aquatic predators lurking from above and their white chest, from predators lurking from below.
5. They can drink salt water, as they feature a special gland that filters out excess salt from your body.
6. Its main food is fish .
7. The smallest species is the blue penguin , which measures only 40 centimeters! And it weighs about 1 kg.
8. As for the highest species, it is called emperor penguin , and adults, on average, measure 1 meter of altu r a and can weigh more than 23 kg.
9. Just as there is a big difference in their sizes, there is also a difference in their life expectancy. An emperor penguin can live up to 20 years and a blue penguin can live as little as 6 years.
10. Most species are monogamous: they choose a single partner for their whole life! In 2012, Argentine researchers discovered that a couple of Magellan penguins had remained faithful to each other for 16 years. Despite being separated for long periods, none of them were linked to another of their kind. Incredible, isn't it?
For other interesting things about penguins, and work done for their conservation, you can visit the Penguin Senntenials websites, the Global Penguin Society and the Wildlife Conservation Society.
