Bowhead whales are among the largest and longest-lived mammals in the world. They play a vital role in the marine ecosystems of the Arctic Ocean, yet relatively little is known about their foraging and diving behaviors. Now, in a paper published in the journal Physical Review Research, a team of scientists from Japan, Greenland and Denmark have detected patterns in the whales’ behavior that could offer clues into how they forage and socialize. Researchers studied 144 days of diving records of 12 bowhead whales tagged in Disko Bay, West Greenland. Because whale diving behavior can be seen as a chaotic, self-sustained oscillation that balances the need for food at depths with the need for oxygen at the surface, the researchers used a dynamical systems chaos approach to uncover patterns within the apparently disorderly collective behavior.

Introducing the Search for Lost Sharks! 🦈 💦 Re:wild’s latest initiative as part of the Search for Lost Species is diving deep into the mysteries of sharks, rays, and chimeras (deep-sea shark-like fish) that have been lost to science for at least 10 years. From the glowing-eyed Crying Izak Shark to the elusive New Ireland Stingaree (not seen since 1825!) to the electric Red Sea Torpedo Ray, the Search for Lost Sharks will bring together researchers, local communities, and citizen scientists to mount searches to find rare and cryptic species. Partnering with Save Our Seas, Beneath The Waves, Minorities in Shark Sciences, PADI AWARE Foundation, Mission Blue / Sylvia Earle Alliance, ReShark, we’re on a mission to rediscover the world’s lost sharks.

📣 Attention, everyone! 👀 Take a closer look at this incredible sight! A bio-inspired diving device successfully disguised as a devil fish! 🐠 Introducing the Batfish-inspired diving apparatus developed by Northwestern Polytechnical University. 🦇🌊 This remarkable innovation has already carried out over 200 missions, including high-biodiversity-friendly, low-impact monitoring of coral reef ecosystems and the protection of rare marine animals in aquariums! 🌿🐋 Netizens can't help but marvel at this bio-inspired marvel, jokingly saying, "This fish-inspired creation only needs to open its mouth to start eating!" 🍽️😄 Stay tuned for more updates on the incredible advancements in bio-inspired technology! The boundaries of innovation continue to be pushed, and nature-inspired solutions are shaping the future. 🌍🔬 #BioInspiration #Innovation #MarineTechnology #NatureInspired #CreativityUnleashed

To what lengths will you go to do research for your next project? I was amazed by the effort the Pixar team put in researching for Finding Nemo. Finding Nemo is a special one for me, as it was my first animated feature film in theatre, and reading about the behind the scenes, made it even more special. Lets take a sneak-peek at how Pixar researched for Finding Nemo. 1. Scuba Diving in Hawaii to experience the world. 2. A large fish tank in the office to observe fishes and their movements. 3. Dissecting fishes and observing dead whale carcasses to understand anatomy. 4. Onboard marine biologists on your team to be as accurate as possible with all the marine flora and fauna. Results? The first output was photo-realistic. The team had to scale down to hyper-realism to make talking fishes look natural! Their dedication didn't just create a film; it birthed an oceanic masterpiece! Remember, in the realm of projects, research isn't just about gathering data; it's about unleashing creativity and uncovering hidden gems that elevate your work to new heights. #pixar #innovation #technology #research

Costal Manta Rays (aka "Reef Mantas") are one of two manta species that you can see while diving in Hawaii. Coastal Mantas (Mobula alfredi) are found in nearshore waters, usually where there are concentrations of plankton. And, unlike their pelagic cousins, Coastal Mantas appear to have a home range and don't migrate. In other words, each island (e.g., Maui, Oahu, the Big Island) has its own population with no apparent interaction between groups - at least according to tracking data. Individual mantas can be identified and tracked by unique pigment spots, which are especially prominent over the ventral abdomen.

Remember the lovable Disney character, Dumbo the elephant, with his iconic oversized ears? Well, meet the real-life aquatic marvels that share his name! Dumbo octopuses gracefully glide through the ocean depths, their fins reminiscent of the beloved elephant's ears. Moving gracefully through the water, Dumbo octopuses employ their ear-like fins for propulsion while using their webbed arms for steering. They primarily prey on pelagic invertebrates that swim above the sea floor, displaying the prowess of foraging predators in their realm. Despite their unique adaptations, Dumbo octopuses are not exempt from predation. Their primary threats come from diving fishes and #marinemammals like tunas, sharks, and dolphins. However, their preference for extreme depths means they are rarely caught in fishing nets, sparing them from significant human impact.

Did you know some sea turtles regularly dive into the #mesopelagic zone? 🐢🌊🤩 Leatherback sea turtles (Dermochelys coriacea) are characterized by their name - instead of carrying a hard shell on their backs, their carapace is covered by a flexible, leathery skin! 🧐 These unique #turtles have been observed diving deeper than 600m, following the diel vertical migration patterns of their prey, #jellyfish! 😋 Interestingly, the #leatherback sea turtle has several adaptations for dealing with cold temperatures in the #pelagic ocean! 🥶 The turtles have a large covering of brown fat on their bodies - which is efficient for retaining heat (similar to hibernating bears!🐻) In addition, their extensive networks of blood vessels are used for countercurrent heat exchange - which is one of natures most efficient ways of transferring heat in the body! 😎💡 #seaturtle #funfact #summerh2020 #mesopelagiczone #mesopelagicorganism #deepsea #marinebiology 📸 Adobe Stock, by Jade

Why Don’t Sea Creatures Implode? Diving into the deep sea is no easy feat for humans. Unlike deep-sea creatures, our bodies aren't built to handle the immense pressure. Creatures near hydrothermal vents, like certain worms, don't have air-filled sacs, so they don't face pressure differences that could crush them. Whales and fish, however, have to expel air from their lungs as they dive deeper to avoid the same fate. The problem for us isn't the pressure on our limbs but the pressure difference in our lungs. It's a fascinating reminder of how diverse and specialized life in the deep sea truly is. Share this video if you've ever wondered why deep sea creatures don't get crushed under pressure! #DeepSeaCreatures #PressureAdaptations #DrTimsAquatics
