So I asked leading shark ethologist and behaviourist, Professor Samuel 'doc' Gruber to elaborate. After pointing out how much pain women feel when they give birth, making the point that suffering has no effect on reproduction, he reminded me that sharks evolved their mating behaviours and the physical structures involved, separately from other animals.
Take a close look at this image. When was it taken? Last year, actually, but it could have been 60 years ago. It shows the beach where I spent most of my childhood summers, since I was a toddler, and where I have spent most of my summer holidays ever since. In the photo, it is as if time has stood still. Those kids playing on the sandbar could have been my brother and me as children.
Those of us who were children back when the moon landings were the pinnacle of wonder, fellow old-timers, will know precisely what I mean. (Crikey, that does rather date me, doesn’t it?)
Clownfish, also known as anemonefish, are feisty critters that vigorously defend their anemone homes from intruders, particularly those of their own species, displaying aggressive behaviour. Anemonefish species living in the same areas exhibit a variety of stripe patterns, ranging from three vertical bars to none, as observed by Kina Hayashi from the Okinawa Institute of Science and Technology, Japan.
Fish feel pain, or don’t they? Despite a growing body of sound evidence that fish do indeed feel pain and are sentient beings capable of all the types of cognition found in the “higher” mammals, with the possible sole exception of the ability to imitate, a group of critics seems to systematically seek to discredit this research. But for what reasons? Ila France Porcher takes a closer look at the stakes involved.
It was seven in the morning and my coffee hadn’t kicked in yet. The dive guide was giving me a slightly more thorough dive briefing than normal. I wasn’t supposed to wear anything colorful or shiny, and black gloves and a hood were required. Also covered in black neoprene, he was putting on chainmail gloves and told me he’d have a pole with him. He said it was more for the potato cods though, not the sharks.
Diving is a recreational pastime, meant to offer pleasure and respite from our hectic work schedules and the relentless flood of troubling news that seems to worsen daily.
We have always strived to write about and focus on the wonderful adventures, the beauty of the underwater realm, and to provide educational infotainment that enhances our experiences and appreciation of what lies beneath the surface.
We have recently returned from another DEMA Show, and it is heartening to witness the dive industry’s resurgence following the pandemic. The show felt like a return to the “old normal.” However, there is an intriguing duality at play here—the old is becoming the new normal in the dive industry.
With nearly three decades of experience in the dive industry, I may be considered a senior member by conventional standards. Yet, at many dive shows, it does not quite feel that way. Amid the attendees, you will find plenty of grey hair, a few walkers, and even some mobility scooters.
I have just booked my flight to the DEMA Show—the world’s largest dive show and industry event. When I made my reservation, I selected Scandinavian Airlines because they now offer travellers the option of purchasing sustainable biofuel as part of the flight ticket, so one can fly with lower CO2 emissions. I also opted to pay for a full carbon offset of my trip. It hurt my wallet, but it lifted the ache I had in my tummy. Being a transatlantic trip, it did not come cheap, but I do not see that one has a choice any longer.
Most of us will agree that we should not be cruel to animals but treat them nicely. We have animal welfare laws in place, for example, and pet owners will testify that their animals—often considered members of the family—have personalities and feelings. It is also widely accepted that a number of wild animals possess considerable intelligence and social skills, such as primates, marine animals, and some birds, to name a few.
