The life of ... an emperor penguin

Hello,

Today, we're looking at the fascinating lives of emperor penguins. These incredible creatures have adapted to survive in the extreme conditions of Antarctica, and in this post, we'll explore their incredible lives.

In late May to early June just before the Antarctic winter sets in, female emperor penguins lay a single egg. They then leave the colony and go on a two month hunt. The male rests the egg on his feet and covers it with warm, feathered skin called the brood pouch. He will eat nothing for these two months. The chick hatches in August and the female returned to take over. She has spent two months feeding and now regurgitates some food for the newly-hatched chick. The male leaves to feed himself as he has been living off his fat reserves for the past two months.

The female keeps the chick in her brood pouch until the sea ice close to the breeding site breaks up as the temperatures warm. The chick is now strong enough to learn how to swim and hunt for themselves. They will return in 5 years to rear their own chicks. Interestingly, 15% of adults will find the same partner from the previous year. We don't know how they recognise them, because there isn't a permanant nest or specific place for them to return to.

Emperor penguins survive the chilling Antarctic winds by standing close together in huddles. They take it in turns to be in the middle before moving back to the outside to allow another individual to warm up. Emperor penguins are amazing swimmers. In fact, they are the deepest-diving birds in the world, reaching depths of over 500m and staying under water for over 20 minutes. They feed on squid, krill and fish.

Emperors are classified as near threatened however, they face a couple of threats. They are eaten by orcas and leopard seals. However a much bigger and long term threat is climate change. As with most species in the Antarctic, climate change is a massive problem. Most of the food chain in Antarctica, relies on the sea ice. The sea ice that is now being rapidly reduced. Just this week, an article in ScienceDaily came out warning about a "Catastrophic Breeding Failure in Emperor Penguins", due to the loss of sea ice. Warmer water temperatures cause problems in fish migration and could lead to thousands of chicks starving each year or the females being too weak to produce eggs that actually have a chance to survive. So, as with all animals, humans are pushing a pretty stable and well adapted population ever closer to extinction.

Coral reefs

Hello! We would love to introduce you to the topic of coral reefs and especially coral reef bleaching, as it is a greatly ignored but certainly significant topic. Have fun! 5 coral reef facts 1. The Great Barrier Reef is the largest living structure on the planet and is 2300 km long! 2. Less than 0.1% of the world's ocean surface is covered in coral reefs. 3. At least 25% of all marine animals live there. 4. Coral reefs are often known as the rainforests of the ocean. 5. In 1 square kilometre of coral reef, up to 35 tons of fish can be 'produced'. The 5 biggest coral reefs in the world 1. Great Barrier Reef (near Australia) 2. Red Sea Coral Reef (near Egypt, Israel and Djibouti) 3. New Caledonia Reef (Pacific Ocean near New Caledonia) 4. The Mesoamerican Barrier Reef (near Mexico, Belize, Guatemala and Honduras) 5. Florida Reef (Atlantic Ocean/Gulf of Mexico near Florida) What is coral? Coral is actually made up of small anim...

Photo Essay || Iceland Series (part 1)

Hi Everyone! I recently went on a school trip to Iceland! It was such an incredible experience (and I'm going to sound cheesy now) but it was also incredible to do it with some of my closest friends! I saw so many incredible things and learnt so much, so I couldn't resist sharing a little Iceland mini series of posts, all about Iceland, both my experiences there and what I saw, but also the way it uses geothermal energy, and the animals, natural landforms and plants that are there. Today I'm sharing some photos of my trip. These are all photos I have taken, and are also the highlights so please bear that in mind as you browse these! I hope it is interesting and inspires you to book a trip to Iceland! The blue lagoon <33 landscapes.... Lost little farmhouses a...

Deforestation and why it’s a problem

Hi everyone, Welcome back to another post. Today we’ll be talking about deforestation and its impacts on our earth. Deforestation, the widespread clearance of natural forests, has been happening for thousands of years. One example is Western Europe, where, two millennia ago, 80% of the land was cloaked in dense forest cover. However, over time, a significant portion of this green expanse was sacrificed to create room for crops, livestock grazing, and as a source of fuel and building materials. Presently, a mere 34% of Western Europe retains its woodland. Today, the tropics deal with the brunt of deforestation. Activities such as mining, agriculture, road construction, and the establishment of vast cattle ranches drive the mass clearance of tropical rainforests. This results in the release of huge amounts of carbon dioxide into the atmosphere, exacerbating the global climate crisis. The consequences come in two waves: first, the reduced number of...

18.10.20 Animal Of The Week: Sloth

Hello, Sorry this didn't come out on Sunday as planned but this week's animal of the week is the sloth because the twentieth of October is Sloth Day. Habitat The sloth resides in Central and South America. It lives in the rainforests there and occasionally drops into the water for a bathe as, believe it or not, they are actually excellent swimmers! Diet Sloths eat leaves, twigs and buds which they find in the rainforest. As they don't have incisors they smack their lips together to make leaves more digestible. Sloths can survive on relatively little food as it takes a while for them to digest it. Sleep and Speed When you think of a sloth, you probably think of this slow, sleepy creature. They actually sleep for about 15 hours a day! Sloths have an extremely low metabolic rate (what basic calories your body needs to survive), which means they move at a slow pace through the trees. On average, sloths travel 40 yards per day ...

16.08.2020 Animal of the week: Elephant

Hello. On the 12th of August it was International Elephant Day, so we decided that this week's post should be about elephants. Elephants are the largest living land mammals. There are three types of elephant; the African bush elephant; the African forest elephant and the Asian elephant. African elephants have larger ears, whereas Asian elephants have smaller ears. Elephants use their trunks to breath, bring food and drink to their mouths and to grasp objects. Elephants' legs are like pillars. They carry the Elephant's massive weight. African bush elephants weigh 6000kg, Asian elephants weigh 4000kg and African forest elephants weigh 2700kg. Basically, they are very heavy.Elephants eat grasses, small plants, bushes, fruit, twigs, tree bark, and roots. Elephants can live up to 70 years old in the wild. They communicate by sight, touch and smell. Sadly, these wonderful mammals are in danger. African elephants are listed as vulne...

Carbon credits

Hi everyone, Welcome back to Green World! Today we're talking about an industry that has expanded massively in the past few years. Carbon credits are one of the measures that companies are taking to reduce CO2 emissions . But how does it actually work? The companies that sell carbon credits fund projects to protect an area of forest or rainforest from deforestation . They then calculate how much carbon dioxide emissions they have saves by protecting this area. This means they can now sell 'negative carbon emissions' to companies. In this way, the companies are funding the protection of said area and are causing negative emissions while doing so meaning that the company can still emit greenhouse gases but can claim to be net zero. One carbon credit is basically the permission to emit one ton of CO2. This is good for the company as well as they are able to advertise as sustainable at a relatively low cost to actually reducing the...

Animals 31-35 in our '50 incredible animals' series

Hi Everyone! Welcome back to our blog, today we are sharing another 5 incredible animals. This is part of a series to celebrate our 50th blog post, all about unusual animals! Enjoy! 31. Pangolins These creatures are often mistaken for reptiles but they are in fact mammals. They are covered in scales and use them to defend themselves because similar to a hedgehog, they curl up into a ball. They eat ants, termites and larvae. They eat using their tongue, which is very long- sometimes even longer than their body! Sadly, Pangolins are in high demand as their meat is considered a delicacy their scales are used in traditional folk remedies, which means that there is an illegal trade. Luckily, there have been many initiatives put in place to help these animals by WWF and similar organisations. 32. Macropinna Microstoma This is a species of fish that live at about 600m below sea level. They hang nearly motionless in the water and have a very unusual...

Jane Goodall

Born: 1934 When Jane was a little girl, she loved climbing trees and reading books. She dreamed that she could go to Africa and see the wild animals there. So Jane flew to Tanzania determined to study chimpanzees in their natural habitat. When she first arrived, none of the chimpanzees would let her get near them. They would always run away at first sight. Jane kept coming back until they let her come closer. However, Jane wanted to become friends with the chimpanzees. So she started the "banana club" which meant that she would share bananas with them every time she visited the chimpanzees. She discovered that chimpanzees have rituals, that they use tools, that their language comprises at least twenty sounds and that they are not vegetarians. Once she rescued an injured chimpanzee and nursed it back to health. When she released it back into the wild, the chimpanzee turned around and hugged her as if to say, "thank you and goodby...

Wildfires

Welcome back to Green World, In the last few months, wildfires have been raging across the globe. Hawaii, Canada, the USA, Spain, Portugal, Italy, Greece, Tunisia and countless more have been affected. But what are the environmental impacts of such a blaze? The USA has had an average of over 70 000 wildfires a year since 2000. In 2020, Californian wildfires emitted more than 90 million metric tons of carbon dioxide, which is more than the state's power industry emits per year. It is estimated that humans start 87% of wildfires. Around the world, 4 million squ. km are hit by wildfires every single year. This emits vast amounts of carbon dioxide, which fuels climate change . The smoke causes air pollution in the entire surrounding area and can lead to respiratory problems in humans. The air pollution also kills birds, including those migrating through the area. Studies also show that socially vulnerable populations are more at risk of harm...
