COVID-19: Anglesey Sea Zoo launches 'Just Giving' campaign

Anglesey Sea Zoo has been a part of the community and business life on Anglesey island, Wales for over 36 years. In that time the aquarium has done a massive amount to protect and nurture local marine life.

Remaining a valuable local employer and a fundamental contributor to Anglesey is very important to us. Frankie Hobro, Anglesey Sea Zoo

Going Through the Paces of GUE’s CCR1 Course

The GUE JJ CCR setup provides a swift and efficient bailout option. If equipped with a BOV, a twist gives access to 14 litres of back gas. This provides plenty of time to make crucial decisions and to figure out what to do next!

I completed a Module 1 course on the Inspiration Classic back in the late ‘90s but found that my limited ability meant that maintaining situational awareness while also having to continually monitor handsets was very difficult. In the early 2000s, I also did a series of technical diving courses with Global Underwater Explorers (GUE), and I still rate these lessons as the most significant dive training that I have ever undertaken.

Salmon Sharks of Alaska

Sharks elicit strong emotions, be it the thrill of a planned encounter underwater or fear propelled by social media and lack of information. Of the more than 400 species of sharks, it is the small family of mackerel sharks that is most iconic. These sharks prompted me to share why one of them, the salmon shark, is an especially remarkable species.

Photographing Giant Manta Rays at Night in Kona Hawaii

Female reef mantas mature in eight to ten years.

Diving with giant manta rays is always an exhilarating experience. Being in the water with these large intelligent animals is always humbling. They are also spectacular subjects for photography and video. Kona Hawaii in the United States is famous for night diving and snorkeling with the local mantas. This can produce stunning images, but it does take some special techniques.

Northern California: A Dive Off the American Wild West Coast

Warm rinse water sloshed in the jug as my car hugged a sharp turn on California’s Pacific Coast Highway. I looked left at the mighty Pacific Ocean, the cliffs tumbling to the sea dotted by rugged pinnacles, stretching farther up the coast than the jam band solo currently playing out of the car speakers. Deep blue, favorable conditions all week, minimal swell, no-wind forecast—only unpredictable visibility could affect the diving today.

Crown-of-thorns starfish lie in wait for corals to recover

It is common knowledge that the crown-of-thorns starfish is the bane of coral reef communities. What is lesser known is that this species does not feed on only corals. Rather, in its juvenile stage, it feeds on algae. Then, as it matures into an adult, it will switch to a diet of corals.

Based on new research reported in the Biology Letters journal, the starfish has the ability to adjust the timing of its dietary change based on the availability of coral in the vicinity.

Whale sharks live an incredibly long time

Many divers dream of the day they find themselves swimming beside a whale shark. Its gentle demeanour and huge size presents a unique humbling experience that is second to none.

Yet, there is much we still do not know about whale sharks.

Today, one of their hidden mysteries have been unlocked–their age.

Until recently, it was hard to fix a number to their age, as they do not have bony structures (otoliths) which are traditionally used to calculate the age of fish.
