A Wedding in The Scuba News Family

I would like all of our readers to join me in congratulating Kathryn, Managing Editor of The Scuba News New Zealand, who should have by now (not sure of the time difference with NZ), married her “man of the sea” Nicholas Curzon.

Why Scubagaskets O-rings all come in black color?

This was a tough decision we had to make. We chose black because of its superior properties over brown or green material. The tests showed that Black Viton compared to Green or Brown Viton, with all parameters constant except for the color, is favorable. It has higher strength, better stability and better elastic properties originally (brand new), and also after exposure to extreme situations that cause material fatigue. It also possesses higher resistance to surface damage.

My Favourite Critter – Seahorses

Every diver has a favourite critter or ocean giant they like to find during their travels and dives. Sharks, nudibranchs, whales and dolphins are often listed as popular but what about seahorses? These unusual and delicate creatures are found around the world and new species continue to be discovered. New Zealand is home to one species of seahorse, the Large-Bellied seahorse and, as its name suggests, it is the largest species of seahorse – growing up to 35cm in length. It lives up to a depth of approximately 100m and as shallow as 10metres and, like other species, is under threat from pollution of habitats and exploitation in commercial industries.

The Gentle Giant – Ungentled

They travel the seas in search of feeding grounds, adding more than 25km under their belt every single day. Whalesharks are filtering the water for small nutritional organisms (plankton, krill, jellyfish, small fish, squid, etc.). In order to survive, a juvenile needs to process at least 21kg (46 pounds) of food on a daily basis. They have been called many names: Lord Fish (Cá Ông) in Vietnam, Butanding and Balilan in the Philippines, they even made it to the back of the 100 peso bill. But I prefer “Gentle Giants” for their calm nature and slowly moving huge bodies. Time is passing with a different speed for them. Their hippy nature backed by a school bus size of a body makes the perfect tool to show us the peace that is the main rule in the underwater world.
