Clidive Lecture Series sees Frogfish Photography come to town

Frogfish Photography give talk on underwater photography to Clidive members and guests in London

Over two years ago we met up with Preeda from Clidive BSAC 410 at a dive show and got chatting about underwater photography. She kindly asked us to come down and do a talk to her club and we readily agreed. However, due to all our overseas travels, we never quite made the dates work and so it took us all this time to get it planned. We were delighted they had persevered and travelled down to London by train, looking forward to the evening ahead.

The Clidive Lecture Series take place at a charming bar called the Troy Bar, in the Shoreditch area of London. Whilst the members and guests ordered some of the Caribbean dishes this place is renowned for, we setup our presentation and camera gear. Soon the room was packed, with only standing room at the very back.

We kicked off with some basics of underwater photography, giving a few tips and techniques, including how to avoid backscatter. We then moved on to showing some of our images from the UK and around the world, telling tales of our underwater adventures and showing how our images are used in magazines and other publications.

We got carried away telling tales about some of our up close and personal marine life encounters and had to admit to our audience that we were over-running, shouts from the slightly oddly lit red room urged us to continue and so we happily over-ran our allotted time. When we did finally finish, we took lots of questions from the crowd and then stayed on for refreshments and to chat together about underwater photography equipment and our favourite dive destinations.

Preeda was kind enough to write about us “A fascinating, interesting and incredibly entertaining talk. The audience was gripped from the moment Nick and Caroline started talking. Nick and Caroline shared lots of secrets of how they took award winning shots, lighting and their camera setup. Their photos told a story but I found the stories behind the images far more fascinating. I did not want the talk to end…

The evening saw people come from 7 different BSAC clubs, non-diving photographers and even family members attend. Profits from the talk will go to The Shark Trust which is Clidive’s nominated charity for this lecture series. Previous talks in this year’s series include Paul Cox from the Shark Trust and Richard Walker from Ghost FIshing. Head to the Clidive website to see what other great talks are coming up.

We love giving talks and offer a number of different lectures to school kids (as part of our work for Sharks4Kids and SeaStraw) as well as diving and photography clubs. For more information email us at info@frogfishphotography.com

Sharks the Ocean’s Greatest Mystery – Part 2

Published

on

Sharks are an incredibly significant animal in human culture of both the past and present, they are an animal that have been embodied in our culture for millennia. They are represented in formats such as books and clothing, but most notably in our TV and films, which is where a large portion of their negative reputation stems from. A popular TV representation of sharks comes from Discovery Channel’s ‘Shark Week’, and I believe sharks are possibly the only animal on our planet to have an entire week dedicated to them every year. However, despite this, we still know more collectively about the surface of the Moon and Mars, about Galaxies outside of our own, and even about animals that have been extinct for millions of years, than we do about sharks.

Sharks are our Ocean’s top predator, and they represent just how little we know about our blue planet. We have put more money into exploring outer space than we have exploring our seas and whilst many people call space the final frontier, I believe the final frontier is our Oceans. There are people that have lived in space for over a year, yet we aren’t able to stay underwater for more than a few short hours, and with each dive, scientists are discovering something new in the deep sea, giving us a better understanding of our oceans and the top predator that lives within them.

What we do not know

It is easier to talk about what we do not know and the implications of not knowing it, we still don’t know where most shark species mate or give birth, knowing this would accelerate conservation efforts for sharks in a huge way as these areas could then have realistic protections placed on them, allowing us to preserve key stages of the Sharks life cycle.

Marine Biologists have stated that the discovery of a White Shark breeding ground would be the holy grail of Ocean Science, but the only reports of White Sharks mating come from a handful of sightings from Fisherman and Sailors, so these cannot be used as an official record.

We know that Sharks mature late in the same way as us humans, it is estimated that some species are estimated to not be sexually mature until their late 30’s and 40’s, which means that these species are at extreme risk of disappearing due to fishing, as they aren’t able to replenish their numbers fast enough when put under extreme fishing pressure. There is a lot of debate over whether Sharks mature at a certain age or a certain size, for example it was estimated that White Sharks mature at four metres in length, however, in South Africa in 2017 a female White Shark was killed by Orcas, and it was determined that she was either immature or hadn’t mated, as there was the presence of a Hymen.

We are also still unsure about the impacts of human activities on Sharks and how losing Sharks, or their habitat, would affect the habitats and environments on land, environments in which we depend on for our survival.

What we do know

New Shark discoveries are made every year, and scientists are predicting that in the next 15-20 years we will be entering the golden age of ocean and shark discoveries. We already know that sharks are the oceans top predator and we have determined that they affect the very mechanics and functions of the Ocean, if we were to remove them, we would be putting the worlds ecosystems at risk of collapsing. Sharks are an integral part of the balance of the oceans, they help by controlling populations of other species, if we were to lose sharks, species such as turtles would have an increase in population, therefore leading to more seagrass being eaten, which is a prime food source for many animals. Thus, other smaller animals would not be able to feed, and their population would decrease, also the decrease of sea grass would affect us humans on earth as the oceans plant life helps to absorb carbon dioxide and create oxygen, and actually up to 75% of the oxygen we breathe is created from the oceans.

We know that some Shark species have complex social relationships that aid in their survival, although this has only been observed in a handful of species. Lemon Sharks form bonds as pups and hunt together in the shallow mangrove swamps of the Bimini Atoll, and will learn and hunt together and learn vital skills needed in their future survival. Hammerheads are possibly the most famous for social interactions as they form huge schools off places such as the Galapagos Islands and it has been observed that the more dominant females swim in the centre of the school and display for the males.

Some shark species, such as the Zebra Shark, have been known to mimic other animals. Zebra sharks are born with stripes (which fade as they get older) and they have the second longest tail (after the Thresher Shark), this helps them to mimic the highly venomous, White-Banded Sea Snake in order to trick predators into avoiding them, they have even been reported to mimic taking a breath at the surface like a sea snake would do.

It has recently been discovered that Greenland Sharks are now the longest lived Vertebrate on our Planet, they are believed to be able to exceed the age of 500, with females not reaching sexual maturity until they are around 150 years old. This was discovered by examining special proteins in their eyes that do not degrade with age. Determining age and sexual maturity are crucial for understanding and managing shark populations as knowing what age a Shark can breed will allow us to gauge what protections a species needs.

It has recently been discovered that female Whale Sharks are able to store sperm to use over a period of time, this is in order to ensure their chance of reproducing, even without recently mating. This is a huge advantage for conserving the species, as Whale Sharks are classed as an endangered species and so, with the number of whale sharks declining, this ensures the species can continue. Along with this, Whale Sharks have also been found to be pregnant with up to 300 pups, and these pups can be at different stages of development due to the staggered use of stored sperm.

Of all things we know there is one thing that is certain, a Shark, no matter the species, is unique and worth more to our world alive than dead. In the next blog we will explore the threats that Sharks face and how we can help Sharks through the tough times ahead.
