Although great hammerhead sharks (Sphyrna mokarran) appear powerful and robust, recent research has shown that they are in fact one of the most fragile shark species, being particularly vulnerable to the stress of capture. Even those that are released after being hooked have a nearly 50% chance of succumbing after their ordeal.1 To better protect these sharks, a greater understanding of their movements is needed. The results of a new study conducted by scientists at the Bimini Biological Field Station in Bimini, Bahamas have provided a major step forward by showing the migration patterns and regional connectivity of great hammerheads between the Bahamas and the United States.

Conservation, sustainability and community are three words that Lembeh Resort in North Sulawesi, Indonesia has always been passionate about. Over the years, the resort has taken measures to reduce their plastic waste and become more environmentally sustainable in all of their operations, but this has now been taken to another level by a team of Lembeh Resort staff that founded the Lembeh Foundation. The Lembeh Foundation is an independent registered Indonesian charitable organization that is working along side local communities on Lembeh Island to provide environmental and economically sustainable solutions to waste management. The core aims of the Lembeh Foundation are to reduce plastic waste, and provide education and economic benefits while improving the health and sustainability of local communities.


Mammalz: an Evolution of Nature Media

Mammalz 01

Founded by wildlife filmmakers Rob Whitehair and Alexander Finden, Mammalz is the “Twitch for Nature”; a next-generation community platform for sharing and interacting with all forms of nature media. Whether you are a professional media maker, scientist, educator, artist, writer, or one of over 600 million nature enthusiasts across the planet, Mammalz provides you with the tools to personalize your experience, share your love of nature, and truly make a difference.

Mammalz, PBC is a Public Benefit Corporation founded in May 2018 and headquartered in San Diego, CA. The Mammalz mission is to promote a greater global public understanding of nature and the environment while acting as a bridge between science, media makers, and the public.

Mammalz, which launched on September 6, 2019, as an iOS beta and web app was developed as a way to bring people who love nature together as a global community onto a single platform to share images, videos, live streams, audio podcasts and 360 video in an effort to further the relationship between humans and the natural world. Since community was the primary goal, Mammalz developed many tools to allow people to engage with each other including commenting on images, creating group Discussions, Chatting with individual users, and even real time Chat during live streams. The app also allows high resolution image uploads up to 2GB and displays them beautifully in any aspect ratio. In the app’s infancy, the level and quality of engagement among Mammalz users with each other has surpassed the company’s expectations and is on its way to outranking any other social media app in existence.

Mammalz 04“What you’ll find on Mammalz are humans, not bots, engaging with the content posted by users,” says Pam Voth, Head of Marketing for Mammalz. “People write in full sentences. They ask intelligent questions and are honestly interested in learning more about the place where a landscape image was shot, how the photographer set up a macro shot of an insect, or where they observed a magnificently colorful bird. The engagement seems polite, respectful, and truly constructive when it comes to comments on photographs being shared on Mammalz.” Voth has been with Mammalz for over a year, starting well before the San Diego-based startup launched its iOS beta and web apps in early September, 2019.

Mammalz members

The Mammalz community is decidedly focused on content about the natural world, but that definition is purposefully broad and includes literally anything that can be considered a way to further the relationship with the natural world. Think safaris to sky-diving, gardening to river rafting, herpetology to archaeology, birding to scuba diving, and everything in between. All accounts are free on Mammalz and eventually, the company will introduce monetization tools which will allow content creators and organizations to earn money to fund their projects through donations and channel subscriptions.

Mammalz 05

Anyone around the world can sign up for a Mammalz account at The iOS beta app is currently available through Apple’s TestFlight. Upon official launch, it will be available on the Apple App Store. The company will also be developing an Android app in 2020.

“Bubbles Away”- Oceanic Omega 3 Review

Thursday, 22 September 2016 02:37

By Brett Lobwein


The Oceanic Omega 3 side exhaust regulator is the perfect choice for underwater photographers, videographers or SCUBA divers who want to avoid any distraction from focusing on the ocean. Apart from the exhaust [flow] bubbles being directed away from my face, as a photographer I really like the Omega 3’s profile. Being a side exhaust means there is not a bulky regulator pushing up against the back of the camera housing as you look through the viewfinder.

The biggest ‘upgrade” of the Omega 3 over the very popular Omega 2 is that it no longer breathes wet. It comes packaged out of the box with a MaxFlex hose* and a ball swivel, making it very comfortable plus dramatically reducing the regulator pulling against your jaw. Tech divers will also love that this regulator is ambidextrous “no up or down”, making it an ideal choice for a side mount setup.

I have managed to test the Omega 3 to a depth of 52 metres (170 feet). The entire way from the surface to 52 metres the Omega 3 delivered the perfect amount of air without the need for any complicated adjustment knobs. A simple twist operated dive/pre-dive switch is very handy to stop any free flowing on the surface.

Oceanic has paired the Omega 3 with the lightweight and top-performing FDX-i first stage. For those who want to explore colder oceanic waters, the FDX-i is ready with an environmentally sealed diaphragm. As you would expect this first stage is also balanced, which ensures the regulator performs consistently at any depth. I have also been very impressed with the well thought out port layout and positioning. The FDX-i uses Oceanic’s Dry Valve Technology (DVT) preventing water or other foreign objects from entering the first stage, ideal if you forget to put the dust cap on.

Complimenting its modern design, the Omega 3 comes in three colour choices—black, white or clear. Personally I love the clear, as it allows you to see the beautifully engineered internal workings of the second stage. After owning the Omega 3 for over 12 months, I am still blown away by its performance.

*Check with your local dealer that this is standard in your location
