Tenerife Hasn't Seen The Last Of  Me

My expectations of Tenerife were far exceeded when I arrived, there's always something different to see in every direction, from picture perfect mountain peaks, rustic villages, tall rigorous cliffs and of course, the open blue sea that surrounds you!

Tenerife - Reconnect With  Nature

“Keep close to nature’s heart…and break clear away, once in a while, and climb a mountain or spend a week in the woods. Wash your spirit clean” - John Muir

Exceptional Luck On Peter  Pan

As we cast off I remembered that I'd been rather spoilt on my first trip out and expected that this one would probably be rather less eventful. I really couldn't have been more wrong.

One Week In South Tenerife!

My first ever week on the Island of Tenerife is coming to a close and I will be sad to go home. I chose the project as I am considering doing a Master’s degree in Marine Conservation.

My Trip As A Marine Biology Student 

"I participated on the Whale and Dolphin Conservation project for a week. After completing my first year of Marine Biology at University, I was looking for a trip to give me inspiration and let me see past all the exams and coursework and know that it does lead to something greater"

Cetacean Conservation: Whales and Dolphins Need Protecting!

The International Union for Conservation of Nature (IUCN) recognizes a total of 87 cetacean species - 15 are ranked as “Critically Endangered”, “Endangered” or “Vulnerable”, and 45 ranked “Data Deficient”. The overall conservation status of cetaceans and their environment is being monitored, but why do they need conserving?

Conscious Cetaceans: The Intelligence of Non-human Persons

We base our understanding of animal intelligence on human intelligence. But what is intelligence? Could a species be superior to humans?

Charismatic Cetaceans: Why We Love Whales And Dolphins - A Blessing And A Curse

Welcome to this four part series about cetaceans! Cetaceans include whales, dolphins and porpoise and their conservation is the main focus of our project here in Tenerife. But why do we humans love cetaceans so much? How do cetaceans interact with their environment? Why have cetaceans been given rights as non-human persons? Why do cetaceans need protecting? Find out everything in our four part Cetacean series!

Whales and dolphins are among a select group called ‘charismatic megafauna’. This means they are big animals with a cute smile - and humans simply love that! Ever wondered why the World Wild Fund for Nature (WWF) logo is a giant panda? Because it is a cute big fluffy animal with a smile! Okay, it is a little more complicated, but only just.

It has been scientifically proven we are hard-wired to respond positively to “cute” – big eyes, round heads, short snouts – and it translates directly into dollar bills (or the currency of your choice). Dolphins are the perfect example of “cute”. Their fixed smile give them a friendly and happy appearance and their anatomy is non-threatening; for example their pectoral fins and streamlined body are much like our arms and torso. Compare this to the image of a spider with eight crawling hairy legs and alien-like eyes. With the exception of some little boys’ obsession with creepy crawlies, people prefer dolphins over spiders.

Relatability matters! We long to travel the world barefoot and jump out of flying contraptions… but when it comes down to it, we are creatures of habit, enjoying familiar situations. We like animals to be similar to us and share intelligence, behaviours and social structures. The more similar, the more we identify with them, and the more we feel a moral duty of care to protect them. Dolphins are very intelligent social creatures with a curious nature. We relate to them when listening to their clicks and whistles, watching their playful behaviour such as jumping and playing, blowing bubbles or playing with objects.

Whales were hunted for their meat, blubber and oil. As science developed it became apparent that these were intelligent social creatures and after the 1970s Save the Whale campaign they were seen as an environmental icon and “gentle giants” who roam the seas peacefully. The whale songs are even used as relaxing meditation music!

This new interest in cetaceans sparked a growth of marine parks and aquariums. Belugas (Delphinapterus leucas) with their unique white colour and their range of facial expressions, were first to be held in captivity. Nowadays, bottlenose dolphins (Tursiops truncatus) are the most common species in marine parks due to their intelligence, trainability, playfulness and friendly appearance as well as the striking killer whales (Orcinus orca). However, in captivity, cetaceans are lacking space and the resemblance to their wild habitat. In the United States the legal requirements for killer whale tank is 15 metres in diameter for two individuals, whereas in the wild an orca can travel up to 160 kilometres a day! As a result, cetaceans can have reduced life expectancies, high levels of stress and even psychosis. Note: If you haven’t yet, you need to watch the critically acclaimed 2013 documentary ‘Blackfish’ which shows the reality behind the tank-life.

It doesn’t take an expert to see that cetaceans are too big and intelligent to be suitable for life in a tank. In some countries dolphins have even received the status of non-human persons, giving them special rights, including it being morally unacceptable to keep them in captivity.

As charismatic megafauna they easily capture public and media attention, and spark political interest, therefore being more likely to receive protection under the Endangered Species Act and funding for their conservation.

Often, they are an essential part of marine ecosystems as they have a high trophic level (meaning they are on top of the food chain) and can act as an indicator species: Their diet and habitat is supported by a high biodiversity; if this biodiversity declines, so does the quality of their habitat and quantity of their food, and eventually cetaceans. So they can tell us a lot about the state of an ecosystem and are of great ecological value!

Combined with their popularity, it makes them the perfect flagship species to raise awareness about other environmental features!

How? Well, because humans want to protect them, and by doing so they indirectly protect the underlying ecosystems and the small slimy ugly species also found in these ecosystems. No matter how interesting you try to make an image of a piece of seaweed look, it won’t be received as well as a dolphin. In fact, using a flagship species such is what non-governmental organisations (NGOs) use in order to get sponsorship, public awareness or media attention to support the conservation of less charismatic species and therefore biodiversity at large.
