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.

Photo Essay | dolphin spotting boat ride

Hi Everyone! Quite a while ago now, me and my family went on a dolphin spotting boat ride, and I've been meaning to share some photos for ages now! We saw so many dolphins very close up and we managed to get some good shots, although it can never be as magical as in person! All photos in this post were taken by me or my family. They were so close to the boat! This photo is stunning! It's under the water! Again - under the water! It was so hard to capture them jumping! This was the boat.... ...

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...

Discussion || Should Everyone Switch To Electric Cars?

Hi Everyone! Thank you so much for joining me today, as I hop on the blog to discuss whether everyone switching to electric cars would really help the environment. In other words, should everyone switch to electric cars? This is the first part of a two-part series, discussing electric cars, so stay tuned for part two!! I would like to start this post by stating that I am by no means an expert. This is knowledge I have from my own experience, and from research I have done. If anything is incorrect please take it as it is and accept that this is a discussion and I am taking on board all opinions from reliable sources on this complex topic. Electric cars are a huge topic when it comes to sustainability and "saving our planet". There is no debating the fact that electric cars are better for the environment than diesel or petrol once they are on the road. But the production of them is often very polluting, with one study show...

25.10.2020 Animal of the week: Snow leopard

Hello everyone, This week's post is about snow leopards. Snow leopards are incredible big cats that roam the mountain ranges of Asia. Snow leopards are very powerful and can climb up and down steep slopes easily, as well as jump up six times their body length. The snow leopard's tail provides balance, agility and warmth. The snow leopard is elusive and solitary and therefore very difficult to spot. They are very important though, because they are at the top of the food chain in this area. Habitat Snow leopards live in northern and central Asia's mountain ranges. These are some of the harshest conditions on earth. However, they white-grey coat with large black spots allows them to blend in with the rocky mountain terrain. They are found in twelve countries including China, Russia and Mongolia. Diet Snow leopards can kill prey up to three times their body weight. This is an incredible feat to pull off as they manage this on their ow...

Animals 36-40 in our '50 incredible animals' series

Hi, As you probably noticed, we took a break from this series, mostly due to having just too much to do. But we're back now with the last three posts. 36. The Pinocchio frog The Pinocchio frog can be found in the Foja Mountains in Indonesia. They mainly eat insects, although little is known about them. They are named because the males have a spike on their noses. They were only discovered in 2008, and this was completely by accident! It remained unnamed scientifically until over ten years later when it was given the name " Litoria pinocchio " . There is very little information about them but Wikipedia states that "the male Pinocchio frog inflates its nose when calling, and the nose decreases in size when the frog is calm and quiet," which I think is hilarious and so interesting! 37. Snub-nosed monkey Especially noticeable due to their curious looks, the snub-nosed monkeys can be found in the forests of central China and northern...

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 ...

How much do you know about climate change? - Quiz

Hi Everyone and welcome back to Green World! For this week's quiz, we thought we would do one on climate change. By this point, climate change is a well known issue, however, we wanted to share some of the specific statistics, some of which are still really surprising. We hope that this is an informative post for you, and it inspires you to take a small action to reducing your own carbon footprint. Questions Roughly how much CO2 is in the atmosphere? (May 2023) a) 380 parts per million b) 400 parts per million c) 420 parts per million True or False? The last time CO2 levels were as high as they are today was 4.5 million years ago. Which summer month in 2021 had the highest temperature since records started almost 150 years ago? a) June b) July c) August True or False? Antarctica loses the same weight as Mount Everest in ice each year. How many p...

LGBTQ+ animals | Pride month special 2022

Hi, As you probably know, it's pride month! Here on Green World we fully support the LGBTQ+ community. Many homophobes and transphobes will tell you that being LGBTQ+ isn't natural. But what they don't know is that over 1 500 different animal species are indeed part of this community! So, today we are going to being covering just a few of these animals. Note: We do not tolerate LGBTQ-phobic comments. All hate comments will be deleted. Sexual Orientation Within the LGBTQ+ community, there are many sexual orientations and most of them can also be found in animals! Here are just a few examples: Rams You probably didn't know, but up to 8% of rams are homosexual. This is quite a lot considering that only 1.7% of US adults identify as homosexual. Laysan albatross 31% of all pairs were lesbian in one study. That is a lot. Bottlenose dolphins One gay pair had a 17 year long relationship. This goes to show that same sex pai...

Ways to help make your household environmentally friendly

We have told you a bit about the problems that the environment is facing in previous posts but we haven’t told you how to help the environment around the house. You don’t even need a garden to make a difference! Ways to help stop global warming Tip 1: Turn the lights off when you leave a room. Tip 2: Walk or cycle on short journeys. Tip 3: Don’t have the windows open and the heaters on at the same time. Tip 4: Never leave your engine running Tip 5: If you can, buy an electric car as these produce less Co2. Ways to help stop plastic pollution Tip 1: Buy a water bottle. It seems simple but every year the UK uses an estimated 13 billion plastic bottles. Tip 2: Use a bar of soap and a bar of shampoo instead of shower gel and bottled shampoo. Some say soap can dry your skin out but if you do your research you can find plastic-free high-quality soap, perhaps at a price but it depends on where you get it from. Tip 3: Make...

Animals 21-25 in our '50 incredible animals' series

Hi Everyone! Here are the next five animals in our current series! We hope you learn something from this. 21. Stick insect Stick insects are masters of disguise. They look like twigs or leaves. This strange appearance makes them hard to spot when stationary. Stick insects are herbivores, feeding on leaves, and can live for up to three years. Their habitat includes most tropical and subtropical regions, but there are a few species that live in temperate areas as well. There are roughly 3 000 different stick insect species! Not much more is known about them, because they are difficult to find. The two main threats to their populations are the pet trade and people killing them so as to frame their carcasses, like butterflies. Their conservation status ranges from critically endangered to least concern - so basically every category that is on the list! 22. Glass frog The glass frog is, well, see through. You can literally ...
