04.10.2020 Animal of The Week: Orca

Hello everyone.

This week's animal of the week is Orca. They are also known as killer whales.

Habitat

Orcas live all over the world. They migrate according to where their prey are. However they are more common in colder waters.

Diet

Orcas are at the top of the food chain and have very diverse diets, eating mainly fish but also penguins, and marine mammals such as seals, and even other whales. They hunt (and live) in groups, making them very dangerous to certain species.

Dangers

There are a few dangers that they face, although for now the population doesn't seem to be suffereing. Some of these are:

-Hunting for entertainment as they are intelligent creatures and so appeal to people who want to test their skills.

-Polluted waters can be a threat as when certain chemicals get into the orca, most likely from their prey, they can be lethal. These can get into the water by oil leaks and chemical leeches.

-Prey as overfishing can cause prey to become scarce

-Fisherman see them as a threat as they can intercept the catch and while some will shoo them away or lure them away by gentle methods, others will shoot them.

-Lastly a threat it shares with nearly all the creatures in the world: climate change. The rising sea levels and changing temperatures can affect their prey as they move to other areas.

Are Orcas dangerous for humans

There have been no fatal attacks on humans in the wild. Four people have been killed by captive orcas. However it is thought that captive orcas suffer due to being confined and can therefore become aggressive.

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 ...

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...

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.... ...

Our 50th post! - and animals 1-5 in the '50 incredible animals' series

Hello Everyone, Today is a special post - to celebrate our 50th post we are starting a new series. This series is about 50 incredible animals. We can't promise that you haven't heard of any of them, but we have tried our best to find some of the most rare and in some cases bizarre animals possible. We can't fit 50 animals into one post so we have split them out over 10 posts. We'll try and publish at least one post every one or two weeks, but you know that we're not very good at keeping to the schedule! So the first five animals that you will (hopefully) find incredible: 1. Dumbo octopus They are the deepest living of all octopus species and are able to pounce on their prey and eat it whole. Their diet includes snails and other creatures they 'hoover up from the ocean floor'. They are called Dumbo elephants as a nod to Disney's elephant because they have fins that resemble the elephants infamous big ears! The...

The limits of the Earth - the planetary boundary model

Hi everyone, So today we're talking about a model that was introduced in 2009 and has offered a new perspective to thinking about environmental issues. The planetary boundary model has 9 boundaries, each has a safe zone. Once the safe zone is exceeded, the stable conditions on our planet are considered at risk, and there can be severe and possibly irreversible changes. The nine boundaries are considered separate however, they greatly affect each other. Novel Entities describes the introduction and accumulation of man-made novel chemical compounds. These include pesticides, nuclear waste and microplastics. Stratospheric Ozone Depletion refers to the depletion of the ozone layer which was a major problem in the 90s. Atmospheric Aerosol Loading is air particle pollution. Ocean Acidification is self-explanatory. The boundary Biochemical Flows is composed of two separate boundaries; nitrogen and phosphorus. Both of the ele...

29.11.2020 Animal Of The Week: Jaguar

Hello, Today (29th November) is world Jaguar day so this week our animal is the Jaguar. The Jaguar is an animal I know pretty much nothing about so I am going to learn a lot too! Jaguars (panthera onca) live for 12 - 15 years. Their heads and bodies are 150-180cm long and their tails are 70-90cm long! They weigh 45 - 110 kg. Habitat Jaguars live primarily in the Amazon Basin, though they can be found in smaller numbers in Central America. They once lived everywhere from central Argentina up to the southwestern United States but since the 1880s they have lost over half of their territory. They are mainly found in tropical rainforests but can live in savannas and grasslands. Diet They eat fish and turtles as they are actually quite competent swimmers as well as deer, iguanas, birds and monkeys; they will eat almost anything! Are they endangered? Jaguars are classed as near endangered and face several threats. South and Central Americ...

Animals 11-15 in our '50 incredible animals' series

Hello, We have another five amazing animals for you today. Enjoy! 11. Dhole This is a dog species which looks rather like a red fox . They are difficult to put into any of the dog subfamilies. They aren't foxes, nor wolves, nor domestic dogs. Dholes are fast runners and live in packs of 5-12 individuals. Although sometimes, different packs will join forces to become a pack of 30 or more individuals! However, these super packs are broken up after a successful hunt. The different packs rarely attack each other as neighbouring packs are often closely related. Dhole packs live in burrows with multiple entrances. They can be found in eastern and southern Asia. They eat wild berries, insects and lizards and as a pack hunt deer, rodents and other wild mammals. Interestingly, unlike other dogs, they rarely kill by biting at the throat. They are also good swimmers! 12. Irrawaddy dolphin The Irrawaddy dolphin can be found in coastal areas of south a...

06.09.2020 Animal Of the Week: Seven-spotted Ladybird

Hello Everyone, Welcome to this week's animal of the week post. This time about the ladybird, and personally I can't wait to find out more about these creatures. Enjoy! Which ladybird we are investigating today? Today, I am telling you about the seven-spotted ladybird (Coccinella septempunctata), which is the most common ladybird in Europe. Other species include the Two Spot Ladybird and other uncommon ladybirds such as the 16 Spot and other peculiar types. Habitat The seven-spotted ladybird lives in a variety of habitats such as meadows, gardens and hedgerows. They can also be found on farmland, especially with crops such as alfalfa, clover and wheat and corn before it grows too tall. Diet The seven-spotted ladybird feeds on a range of aphid species. This is why they are often referred to as a gardener's best friend as they eat these creatures who can damage plants. They can also eat white flies and anything else that is soft-bo...

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...
