oneoceanresearch Enjoyed all the fun submissions on last post it is a galapagos shark #carcharhinusgalapagensis one of our home zone species of shark. this is a pack forming species which suggests social coordination. if you see just one be aware there may be more close by. during the day this species generally swims slowly coasting in formed aggregations or easily exploring the environment for change. #homeboys #galapagosshark #cgalapagensis photo @oceanramsey #helpsavesharks

oneoceanresearch Technically the term “fish” can refer to singular or plural individual(s) of the same species. whereas “fishes” is plural for a variety of species. homie @tyler_awgz dive to meet one whale shark in oslob. #rhincodontypus #whaleshark #spotshark so very cool these spotted giants. @honeygirl_ @keiko_conservation_k911 @keiko_conservation

oneoceanresearch Short-finned pilot whales #globicephalamacrorhynchus @juansharks #pilotwhale #portrait. these marine predators are one of hawai’i species of 18 #odontocetes or toothed whale recognized by #drrobinbaird of @cascadiaresearch. this is the most common species encountered 25% of all sightings since the year 2000. #drbaird was the first to scientifically describe resident and transient behavioral patterns among cetaceans which then became an available connotation for sharks. behavioral studies among lemon sharks, leopard sharks and great white sharks and others have been published as humans study the natural environment from a sharks perspective. #openoceanresearch #longlivefieldscience #citizenscience #connectivity #marinemegafauna #sharks

oneoceanresearch The establishment of a sharks lateral line is highly specialized. these pores extend not only along each side of the shark from nose to tail but also around the face. especially in close range investigation a shark often closes its eyes relying on the strength of its other senses. (this can be hard to picture because humans don’t identify electrical and mechanical charges but sharks are very sensitive to them.) when the sharks eyes are closed you should be at a heightened level of awareness because they can feel pressure waves of subtle movements nearby. can anyone name the shark species in this picture ? photo by @sdmdiving πŸ˜ŽπŸ‘ŒπŸ½ #sharksarecool #fisharecool #savetheocean #sharkandmarineconservation

oneoceanresearch If find a shark in distress in hawai’i//on the island of o’ahu please send in a marked location,time, and photo of this animal. our program generally does not practice hook removal to avoid further stress to the shark in the process (it can be difficult) and many rust out naturally 🀞🏽🀞🏽. of critical attention would be an entangled shark like this one ☝🏿 our favorite #roxygirl 😒because we want to keep track of the health and nature of these animals. it is one of our most important developing research projects. please forward attn: oneoceandiving@gmail.com subject heading #sharkentanglementproject 🌟🦈 by @juansharks training under @oceanramsey @oneoceandiving

oneoceanresearch Micro larval pelagic c***s live at the surface and drift with the movement of the sea. small often iridescent and seemingly invisible to much of human life these #planktons are very important to the open ocean and the planet. they feed higher trophies levels and provide nutrients to the pelagic surface waters. planktonic #microbiota are responsible for the largest known migration on the planet called #dvm or diel vertical migration. in marine and freshwater environments tiny microorganisms surface with the night and drop in depth with sunrise. πŸ”¬πŸ€―πŸ˜Ž #zooplankton

oneoceanresearch #requiem ground sharks have a protective #nictitatingmembrane that acts as a shield when the shark is within close proximity to a potential threat they feel may damage the eye. flashing this membrane structured like an eyelid is a sign of caution or discomfort in order to surely protect the very valuable eyes of these apex predator #tigershark #eyeofthetiger

oneoceanresearch The eyes of fish are structurally very similar to other vertebrates. they have a lens, cornea, rods and cones but no eyelids. without air spaces the eyes do not focus and in #elasmobranchs the lens is slightly flattened which allows the pupil to dilate and constrict to accommodate light/depth. great whites (like the one pictured above) have adapted a special optical advantage called the #snellswindow. they can see straight up to watch sea lions while hidden below in the depths using #countershading #camoflauge and even into the air from the surface! #sharkeyes #sharkvision #viewtheworldfromasharksperspective

oneoceanresearch Unlike bony fishes sharks carry no gas bladder. instead of air spaces they rely on a lipid dense oil saturating a very large liver that encompasses 20-30% of the sharks body mass. despite a cartilage skeleton sharks are so muscular they are negatively buoyant. without forward propulsion and lift (using fins, cephalofoil) they will sink. this is how sharks like #deepblue have been filmed “sleeping” by drifting to great depths at a low metabolic function and slowly swimming up again just to rest and sink once more. shark pictured @marinecsiorg #202 #chelsea in isla guadalupe. #oneoceanresearch #sharkscience #buoyancy #freefall #sharksleep

oneoceanresearch Many bony fish carry a gas bladder to achieve neutral buoyancy. they rely on the passage of oxygen through their circulatory system to diffuse in/out and fill or depress to raise or lower in depth. fish with spiny fins have a #physoclistous gas bladder that is separate from the stomach and inflation is associated with the #retemirabilia (countercurrent network of blood vessels) and an additional gas gland. soft rayed fishes have #physostomous gas bladder connected to their stomach by a pneumatic duct that they fill by swallowing air at the surface (some also carry a gas gland). in contrast sharks have a very dense liver the physiology of which will be described in our next post ;) #fishscience #ichthyology #biologylesson #pilotfish #oneoceanresearch #savesharks #sharkandmarineconservation #sharkscience

oneoceanresearch #oceanicwhitetip were once described as one of the most abundant species of animal on the planet! now global #s are down over 99%!!!!! the species i would most love to meet nextπŸ™πŸΏπŸ’• (&smooth hammers;). owt have broad paddle shape fins (because they love hugging) and also to cruise efficiently over long distances in open ocean. they have a very defined sense of smell and have been documented smelling into the air!(outside of water) to track food source. often seen following cetaceans like false killers or pilots these lovely fish need your help! #tellsomeoneyouknowaboutsharks #speakupforsharks #swimwithsharks #divewithsharks #eatlessfish #supportlocalfisheries #choosesustainably #getecofriendly & #helpsaveshark photo @kokocousteau πŸ™ŒπŸ½

oneoceanresearch πŸŸπŸ‘@waynelevinimages #bwphotography schooling fish swim together in tight quarters hardly brushing fins thanks to the development of a #lateralline. this intensely pressure sensitive system is made of a line of pores on either side of the body filled with a gel like substance and individual hair cells called #neuromasts. the movement of water waves that contact the gel move the nerve endings attached to the hair cells allowing the fish to feel the subtle twists and turns of the fish next to it and consecutively within the school so that they move almost as a single animal #flashmob. delicately traversing the sea in the safety of numbers schooling fishes like this tight #baitball are getting more and more rare to see, find &photograph. we are all connected. every life matters. download #seafoodwatch @seafoodwatch by @montereybayaquarium #getsmart #oceanconscious and #eatsustainable !! @oneoceanconservation
