What secrets lie deep in the ocean’s darkness? ?? In a study published in Elsevier's?Deep-Sea Research Part I, scientists at MBARI have introduced the world to?Bathydevius caudactylus, a newly discovered nudibranch found in the bathypelagic zone, over 2,200 meters below the surface. Known as the “ghostly nudibranch,”?Bathydevius?is bioluminescent, displaying a glowing defense mechanism when it feels threatened. Unlike typical nudibranchs that live on the ocean floor,?Bathydevius?floats freely in open water. Observing it in the wild, researchers saw it capture prey with a hood, feeding on crustaceans—a trait so unique that it required the creation of a new nudibranch family. With vast stretches of the deep ocean yet to be explored, findings like this reveal just how much is yet to be discovered. #MarineBiology #DeepSea #Evolution

While exploring the deep ocean, either at sea or from shore, you’ve likely seen something you didn’t recognize. NOAA Ocean Exploration's Benthic Deepwater Animal Identification Guide was developed to help scientists and others identify unfamiliar seafloor species (both known and unknown)...and we've just launched a new version with even more critters! Updated in 2024, the #benthicID guide is now searchable and includes animals seen in deep waters of both the Pacific and Atlantic oceans. Learn more and access the guide: https://lnkd.in/d2nWzEAD [Image: This sponge was unknown to science when it first appeared in the guide. It has since been formally described and named Advhena magnifica, and the guide has been updated accordingly.] #ocean #exploration #marinelife #science #guide

Flying fish do not have a special adaptation to breathe outside of water. During the time they spend in the air, they rely on the oxygen they have taken in while underwater. Flying fish belong to the family Exocoetidae and are typically found in tropical and subtropical seas. These fish can leap out of the water and glide over short distances by using their fins. This ability helps them escape predators or search for food. Fins: The pectoral (chest) fins of flying fish are very large and function like wings. In some species, the pelvic (abdominal) fins also expand, acting as a second pair of wings. #Fish #Flying #Science #Sea

We require strict protective measures for marine life during offshore wind activities. We require that “acoustic exclusion zones” are established in the areas where geophysical surveys or construction is happening. This means that the zone must be clear of any marine mammals and sea turtles for a designated amount of time before acoustic sound sources can be used. Visual monitoring by a trained, third-party, independent Protected Species Observer (PSO) is required to maintain the integrity of these zones. These PSOs are trained to watch for marine life and if a mammal is detected within a certain distance, then the PSO orders that any sound sources are shut down until the mammal has left the area.

Protecting marine life is a critical part of the process while installing offshore wind turbines.

Fierce and fabulous, the colorful mantis shrimp packs a punch. In fact, it packs the most powerful punch in the animal kingdom — not too bad for an animal synonymous with the most diminutive among us! According to an interdisciplinary team at Harvard, the carnivorous crustacean’s club-like arms “accelerate faster than a bullet out of a gun and just one strike can knock the arm off a crab.” They know this because they built a tiny 1.5-gram robot to study the mechanics of a mantis strike. Ultimately, they were able to unlock the four distinct phases of a punch using high-speed imagery and an interdisciplinary approach. The researchers believe that “combining physical and analytical models could help biologists understand and roboticists mimic some of nature’s other extraordinary feats.” You can read more: https://lnkd.in/ewfPwRb4 These tiny boxers were spotted during the #SalasyGomezRidge expedition, where an international team of scientists observed individual seamounts harboring distinct ecosystems and awe-inspiring deep-sea creatures — experts believe the unique attributes of each underwater mountain may warrant more comprehensive protection for the whole region.

Looks like a shark. Swims like a shark. Sometimes referred to as a shark. Is it a shark? ?? Spoiler: This is a chimaera, so while related to sharks, it is not technically one itself. Chimaeras, also called ghost sharks, are a type of cartilaginous fish. This means that that their skeleton is made of flexible cartilage instead of hard bones, which is something they have in common with sharks. However, there are a few major differences between the two. Chimaeras have a long, whip-like tail and large pectoral fins, giving them a distinct appearance from their better known relatives. Their dorsal fin also contains a retractable venomous spine that they can use to fend off potential predators. True sharks have rows of sharp, replaceable teeth, but chimaeras have bony plates that grow continuously throughout their lives. The plates are adapted to crush the shells of the crustaceans that they feed on. These chimaera were filmed while OceanX was on mission in??Norway. Chimaeras live all over, except for the Arctic and Antarctic oceans, so we're always keeping our eyes peeled for them on our sub and ROV dives. #chimaera #ghostshark #shark #fish #norway #deepsea #oceancreature #oceanfacts

Good information and important to share with folks.

An underwater mountain chain off Rapa Nui, or Easter Island, has revealed a treasure trove of deep-sea species, according to researchers on a Schmidt Ocean Institute expedition. The team found at least 50 new-to-science species, including a deep-sea dragonfish and a jellyfish-like creature known as the flying spaghetti monster, which had never been spotted in this region before. The team also spotted the deepest photosynthesis-dependent animal ever found - a wrinkle coral. A further 50 specimens, which have yet to be analyzed, are believed to be new species. The discovery of this astonishing array of deep-sea species highlights the importance of continuing to explore and study our oceans. #deepsea #oceanexploration #newspecies #science
