We can all appreciate a good idea when we hear one. But what about those great ideas that really make a difference, that help make the world a better place? TED, a nonprofit founded in 1984, is devoted to spreading the word about great ideas. Every year TED grants a $100,000 prize to an individual with “One Wish to Save The World” and ARKive patrons E.O. Wilson and Dr. Sylvia Earle have both been recipients in the past.

The 2012 TED prize will be awarded at the end of this month, and what better time to share some of the greatest ideas that were inspired by nature and are helping to change the world, even if just a little bit.

Temp-savvy termites

When those warmer months come around, it’s easy for us to turn on a fan or the air conditioner and escape the heat. However, some people have taken a cue from the termite and its method for staying cool in the hot African sun that doesn’t use energy at all. By opening and closing different vents in the mound, termites keep internal temperatures at a tolerable and constant 87°F. Designers of a residential building in Zimbabwe caught on to the termite’s bright idea and incorporated this vent system into their construction plan, saving 90% of the traditional energy costs of a building similar in size.

When you think of an elephant, one of the first things that comes to mind is undoubtedly its trunk. A handy adaptation, the African elephant uses its trunk and two prehensile finger-like lips to feed from the ground and trees, breaking off branches and picking leaves and fruit. Recognizing how helpful an elephant trunk can be, many robotic arms used in assembly line production and even medical equipment have been designed using the trunk for inspiration.

Looking at this picture of the kingfisher, it’s not hard to see how scientists used its sleek, aerodynamic design when conceptualising Japan’s ultrafast bullet train. Kingfishers have been reported to dive into water with barely a splash in search of fish. Borrowing from the bird’s design, the bullet train uses 20% less fuel than the traditional train.

You might notice swimmers wearing interesting ensembles at the upcoming Olympics in London this year. Athletes have increasingly been sporting swimsuits inspired by sharks and their skin. The specially designed suits reduce drag by up to 4% and feature a texture similar to small “teeth” that direct the flow of water around the swimmer.

We’ve explored some fascinating ideas, inspired by species, that have helped change the world. Do you know of any other great ideas inspired by nature? Why not share them in the comments below!

We hope you enjoyed our last From the West End to Wildlife blog featuring Gina Beck and Tori Johns’ favourite species! Today, we’re back with another instalment, quizzing the best of the West End to find out what their favourite species are, and hear about some fascinating wildlife experiences!

Oliver Tompsett

Oliver is currently playing bad-boy wannabe Drew in Rock of Ages, and has chosen a fellow primate as his favourite species, “I love the gorilla; such a powerful creature, yet always so gentle to its family.

Gorilla families are led by an adult male known as a silverback

Oliver is quite right; despite their King Kong reputation, gorillas are actually not particularly aggressive animals, and live in strongly bonded family groups led by a male known as a silverback. There are two species of this impressive primate, the eastern gorilla and the western gorilla, classified as Endangered and Critically Endangered, respectively, on the IUCN Red List. The main threats to these majestic creatures are the loss and fragmentation of habitat, and poaching.

Did you know?

  • Gorillas are the largest of the living apes; adult male gorillas can stand at a height of 1.7 metres.
  • At about 14 years of age, the hair on the saddle of a male’s back turns whitish, hence the name ‘silverback’.
  • Despite their massive size, gorillas are herbivorous, feeding mainly on leaves.
  • Gorillas build nests to sleep in at night, usually on the ground.

Oliver moves from land to sea for the location of his favourite wildlife experience to date, “Snorkelling in Egypt! It was truly like being super-imposed into Finding Nemo! The colours were incredible!

One of the stars of Finding Nemo was Crush the green turtle, and Oliver may well have seen one of Crush’s relatives, gliding gracefully over the reef, during his snorkelling adventures in Egypt.

There are hundreds more intriguing species to be found off the coast of Egypt, and as an avid rocker, I’m sure that Oliver’s character Drew would have loved to have seen the super-cool giant guitarfish!

The giant guitarfish is named for its strange guitar-like shape!

Our favourite rocker’s trip was ended rather abruptly thanks to the appearance of another rather large fish species…

The guide saw a dangerous shark and told us all to get back on the boat. Luckily I didn’t see it or I would have cried. I am obsessed with and petrified of sharks!

Oliver may well be terrified of sharks, but we have found one West End wonder who loves them…

 

Sarah Earnshaw

When asked about her favourite species, Sarah replied without hesitation, “For me it has to be the great white shark. I’m absolutely fascinated by them. They have such power, yet are incredibly graceful. I mean, don’t get me wrong, if I came face to face with one I’d be terrified but there’s something so intriguing about their mystery and danger!

Great white shark image

Great white sharks are highly skilled marine predators

The great white shark is often thought of as a fearsome man-eater, but this is not the case; it feeds predominantly on fish, but will also eat turtles, molluscs and small marine mammals.  Like other sharks and rays, the great white shark has a skeleton made of cartilage, rather than bone. This mighty species uses its keen senses of smell, sound location and electroreception to detect weak and injured prey from great distances.

Sarah sticks to the marine realm for her favourite wildlife experience, “I had the most fantastic experience when I was in New Zealand. I went whale and dolphin watching. We saw three beautiful humpback whales, and dolphins literally for as far as the eye could see! There was something so special about seeing the whales diving and their tails rising above the surface. It was an experience I’ll never forget.

Did you know?

  • The humpback whale gets its name from the way it arches its back when it dives deeply or ‘sounds’.
  • The pattern on the underside of the flukes is unique to each whale, and can be used to photo-identify individuals.
  • Humpback whales are known to herd their prey into a cluster by blowing a net of bubbles around shoals of potential food, making it easier to catch a big mouthful at once.
  • Male humpback whales sing a complex song to attract mates.

Sarah is a firm believer in wildlife conservation, “Conservation is extremely important. Without it, not only would we lose some of the most interesting, beautiful and diverse creatures in the world, we also risk a real disruption to the balance of nature as we know it.

A Chinese hotel group is aiding efforts to conserve dwindling shark stocks with its announcement that it will no longer serve shark fin soup in its establishments.

Shark Shangri-La

Shark fin soup is a delicacy in China, fetching anywhere between £48 and £100 per bowl depending on the species in question. This traditional dish comes at a high cost to the world’s oceans, however, with an estimated 26 million to 73 million sharks killed each year for the shark fin soup industry. Almost a third of these are consumed at banquets during the Chinese new year period.

Yet as China prepares to welcome in the Year of the Dragon, hotel group Shangri-La has announced that it will remove shark fin soup from its restaurants. This decision will affect all 72 of the group’s hotels, marking a big step towards the conservation of the ocean’s top predators.

Saying No

Hong Kong is at the centre of the shark fin trade, and an important turning point for shark conservation was reached in November 2011 when the Peninsula hotel became the first traditional hotel in the region to stop serving shark fin soup. Conservation efforts have been further boosted by basketball star and WildAid international ambassador Yao Ming speaking out against the delicacy.

Following the Peninsula hotel’s decision, 112 companies signed up to a ‘Say No’ initiative, vowing to remove shark fin soup from corporate banquets.

Stanley Shea, of Hong Kong-based NGO Bloom Association, is pleased with the progress, but highlights that further steps are needed in order to preserve the marine environment, “We are seeing announcements one by one, but it is not enough just to stop serving shark fin. Hotels also need to put in place public policies on sustainable seafood sourcing.”

A responsibility to sustainability

The Shangri-La Hotels and Resorts chain is taking its contribution to marine conservation one step further, and has recently unveiled a ‘sustainable seafood policy’, which commits the company to ensuring that it phases out the use of other threatened marine species such as bluefin tuna and Chilean sea bass.

Conservationists are welcoming this move as a positive sign that some major corporations are beginning to embrace the idea of sustainability.

This is very significant,” says Bertha Lo of the Hong Kong Shark Foundation. “Two leading hotel groups have now sent a very strong message to the food and beverage industry and the wedding industry. I don’t see why others don’t follow suit.”

Next steps

Despite these positive moves, much remains to be done for marine conservation. A recent survey of 64 of Hong Kong’s leading hotels found that at least one threatened marine species was found on 98% of the menus. Almost all of these hotels served shark fin soup, and only a minimal number had adopted a policy on the sustainable sourcing of seafood.

The Bloom Association has conducted surveys which suggest that 88% of consumers want the authorities to take action to prevent the sale of products which involve killing threatened species. Conservationists are now calling for an increase in social responsibility programmes within the corporate sector.

Plans have been put forward to establish the world’s largest marine protected area, in the Coral Sea off the coast of Australia.

The Coral Sea

Located on the northeast coast of Australia, the Coral Sea stretches from the boundary of the Great Barrier Reef Marine Park to the Pacific Islands. It is home to a diverse range of corals, fish, seabirds, reptiles and marine mammals, including threatened species such as the loggerhead turtle, blue whale and great white shark.

If the proposal for the protected area is approved, it would result in the protection of 972,000 square kilometres of the Coral Sea, an area roughly the size of France and Germany combined.

The environment minister, Tony Burke, explains, “The environmental significance of the Coral Sea lies in its diverse array of coral reefs, sandy cays, deep sea plains and canyons. It contains more than 20 outstanding examples of isolated tropical reefs, sandy cays and islands.”

Variable protection

The level of protection will vary across the planned marine reserve, with around half of the total area being designated as a ‘no take’ zone, where fishing will be prohibited. Other areas of the Coral Sea will allow varying levels of recreational and commercial fishing, depending on their designation. While this is welcomed by some, it falls short of conservationists’ hopes for a completely protected marine area.

A statement by the World Wide Fund for Nature (WWF) said, “The draft plan proposes to set aside only the eastern Coral Sea as a safe haven for marine life. Many of the jewels in the crown of the Coral Sea therefore remain unprotected. Only two of about 25 unprotected reefs are given a high level of protection.

As well as protecting the flora and fauna of the Coral Sea, the planned park will also help to preserve historical sites, including the wrecks of ships sunk in 1942 during the Battle of the Coral Sea.

The plans for the Coral Sea marine reserve will be finalised in 90 days, when the government will decide on the limits to be imposed on the protected area.

Name: Scalloped hammerhead (Sphyrna lewini)

Hammerhead shark Survival characterStats:

Status – Endangered (EN)

Length - up to 430 cm

Weight - up to 152 kg

Interesting fact:

This shark’s oddly shaped head is thought to be a mechanism to spread out its highly specialised sense organs, which amongst other things help it to detect electrical currents created by its prey. A useful skill to have when you have an entire ocean to scan for food!

Where am I found?

The wide-ranging scalloped hammerhead occurs right the way around the world, in warm temperate and tropical waters. It can be found in the Atlantic, Indian and Pacific Oceans, and also possibly the Mediterranean Sea. It swims at depths of 0 and 275 metres and regularly enters bays and estuaries.

What do I eat?

Adult scalloped hammerheads feed on a range of ocean critters including fish, squid, lobsters, crabs, shrimps, rays and even other sharks! The teeth of the scalloped hammerhead are best suited to seizing prey that can be swallowed whole, rather than ripping into larger prey.

How do I live?

A strange-looking creature, the strange hammer-shaped head is thought to be a mechanism to maximise the area of the sensory organs that detect electric currents, chemicals in the water, and temperature changes. Female scalloped hammerheads gather in impressively large schools around underwater mountains known as seamounts, where they perform a wide range of poorly-understood behaviours. These aggregations are thought to be a result of many sharks, particularly younger females, seeking refuge in a safe place near a rich food supply.

During the 9 to 10 month gestation, the eggs of the scalloped hammerhead hatch inside the body of the female. They are then nourished by a yolk sac until the female gives birth to between 15 and 31 live young in shallow waters during the summer.

Why am I threatened?

The scallopd hammerhead is currently threatened by fishing, both as a commercial catch for its liver and fins, and as by-catch.
