Good day shark people! this week I have the pleasure to release the interview with Italian freediver Simona Auteri. Simona will share her experience as a volunteer in Madagascar with whales sharks, she is gonna talk about the work she made as a volunteer and what it's like to dive with these majestic animals. So hold your breath and let's dive with whale sharks!

Hi Simona, first question to introduced a bit yourself to readers: What is your background (ie. biology, photography, other..)?
I am actually an architect!
I grew up in Genova, a harbour town in the north of Italy and the sea has always been my passion. Whilst I have always explored the sea through snorkeling or sailing, I discovered freediving whilst on a trip to the Philippines and that episode pretty much changed my life!
When did you first start to be interested in sharks?
Freediving challenged a lot of my beliefs and preconceptions and the more I read about the underwater world the more I wanted to discover.
I became interested in marine biology and read lots of books.
My perception about sharks started shifting.
The feeling of fear started to transform in curiosity and appreciation of their role as apex predators within the ocean ecosystem, and the more I documented myself the more I became fascinated with their intelligence and their world.
Can you talk a bit more about your experience with whale sharks?
Whale sharks are not whales and whilst they don’t have huge teeth, they are real sharks. Unlike whales, they breathe and feed through the water they filter.
They are the largest living fish on earth, reaching up to 20 m in length and weight up to 34 tonnes, yet their behaviour is largely unknown.
Whilst they are big and still classify as shark, whale sharks use their strong sense of smell to find plankton, filtering seawater at the staggering rate of 600,000 litres per hour so to feed about 22 kilos of plankton a day.

Whale sharks are classified as endangered species and there is huge value in participating in conservation projects with whale They love tropical waters and Madagascar is one of the aggregation places where young juvenile male whale sharks come feeding.
Founded by Stella Diamant, Madagascar Whale Shark Project aims to study and protect whale sharks in Madagascar, while raising awareness and empowering local communities through ecotourism, making the locals realize that a live shark is worth more than a dead shark.
Whale sharks also lack protection in Madagascar and, in the face of growing tourism, no local regulations were in place to regulate interactions, hence one of the project's missions is to set up a code of conduct for sustainable Whale tour operators to approach whale sharks in the area.
The project is co-supervised by whale shark expert Dr. Simon Pierce and marine megafauna specialist Dr. Jeremy Kiszka.

Madagascar Whale Shark Project deploys volunteers to identify each whale shark encountered. In fact, each whale shark has a unique pattern of white dots that resemble a constellation (hence the malagasy name Milky Way Sharks) which identify each individual like a set of fingerprints.
Us volunteer would take pictures of the left hand side of the unique pattern behind its gills and above its pectoral fins together with a recording of relevant GPS location data and would later upload them onto the global sighting database WhaleShark.org, thus helping researchers count how many sharks are seen and track their movements and behaviours over time.
In 2019 alone the Madagascar Whale Shark Project together with us volunteers and with the collaboration of the sustainable tour operator Les Baleines Rand’Eau, recorded 413 encounters with whale sharks in Nosy Be with a total of 97 days at sea*.
What are your best memories of the time you spent in Madagascar? And what is the most surprising thing you could see?
One of the most memorable moments was to free a whale shark who was growing into a thick rope around its neck.
I noticed something was wrong from afar and quickly called guide Thomas from the sustainable Whale operator Les Baleines Rand’eau to join me in the water with a knife to cut the rope. Thomas is a strong freediver and we quickly developed the plan to for him to cut the rope attached to the whale shark neck whilst I would try and remove it from its body.
The whale shark was coming to the surface towards us, as if to pledge for help, and at that time we got hold of the rope.
Whilst Thomas started cutting the rope, the whale shark started sinking in the deep real fast and we had to use our freediving skills to equalise our ears whilst cutting and freeing the whale shark.
It took us three dives to finally free the animal which kept on diving deep and then returning to the surface to find us again.
Removing the rope revealed thick cuts through its neck, however our team saw the same whale shark the day after and it was healthy and its scars were recovering.
Would you recommend this experience to people willing to reconnect with nature?
Totally! By supporting marine conservation NGOs you will help to protect threatened marine life and play a part in protecting our oceans.
The experiences made on the field are memorable and truly make you fall in love with our planet and ecosystem. Eventually, as Jacques Cousteau quote goes, 'People will only protect what they love.'
As a freediver, how can you describe the feelings you have while diving with whale sharks?
No two days were the same at sea.
Whale sharks are majestic and oblivious, they have a brain the size of a walnut despite their size, and have lateral sight so it happens that they realize you are there once they are really close to you which can be really funny.
Also it can happen that a really young individual starts playing with you and following you around really close, opening and closing their large mouth in continuous motion.
This is hilarious to watch and yet at the same time you have to be fast in swimming away whilst being careful to avoid touching the animal.
Not only Nosy Be bay is full of whale sharks but the abundance of krill and plankton brings a wealth of megafauna species.
The blue is astonishing and words cannot describe the feelings of connection and peace found whilst freediving with a fleet of Mobula Rays, or the joy of an encounter with a family of curious dolphins that come and play, or observing the wise turtles feeding in their habitat.
The bay is also home to a large family of the very rare Omura’s Whales which were only discovered in the area in 2012 by a team of scientists led by marine Biologist Salvatore Cerchio.

I met Salvatore Cerchio in a conference during my time in Madagascar as he was there to drop hydrophones at 300m below sea level to record the sounds of the Omura’s whales songs. Through their year long recordings, they could find that Omura’s whales are actually a resident species of Nosy Be bay.
He made us listen to their songs, and we could distinguish single individuals songs and choir songs, in a similar way that birds and crickets sing to interact with each other.
What’s the message you want to spread to raise awareness on shark conservation?
Read, inform yourself, participate in ocean conservation programs, do not buy fish from supermarkets and most of all fall in love with our oceans and their inhabitants
We are at the end of this interview. It was amazing to hear the experience with whale sharks of Simona! If you'd like to see other pictures of whale sharks I highly suggest you to check out Simona's IG page by clicking here.
