oneoceanresearch Really cool modern study about the connectivity of an ecosystem #sharkandmarineconservation online: https://www.frontiersin.org/articles/10.3389/fmars.2014.00028/full addressing the over harvesting of large sharks plowing the same trends we see on land in the absence of apex predators. these animals are important to the balances in nature and reflect some of the toughest lessons of #humanimpact. in this study of multiple habitats involving green turtles overpopulating basins without shark and reducing sea grasses to the point of habitat collapse. sharks are vital to the structure and function of these and other ecosystem and “support fisheries as a carbon sink” picture 1 @thomas.nolting of a tiger shark #galeocerdocuvier bahamas picture 2: “schematic representation of potential ecosystem responses to loss of turtles (moving from the top to the left) or loss of large sharks with turtle conservation (moving from the top to the right)” picture 3: “responses of seagrasses to green turtle grazing across ecological contexts”

oneoceanresearch @jim_abernethy @jim_abernethy @jim_abernethy with shark photography sometimes results in our friends playing with our cameras. 73 slr's have been taken by tigers under our shark expedition vessel since i started large predatory shark ecotourism trips in 1999. nineteen of them were mine like this one. they seem to act like kids fighting over a c*****r box toy! so much fun to watch and enjoy. 2 were never found, at least not yet! photographer paul krupela @jim_abernethy #saveprotectedanimals #savesharks #sharks #tigershark #saveplanet #saveoceans #emmathetiger #tigerbeach #finbannow #saveearth #conservation #underwaterphotography #jimabernethysscubaadventures

oneoceanresearch Some of the ways that fishes use to navigate is by smell, vision and electromagnetic sense. they can also tune in to seafloor structure by feeling upcurrents and subtle changes in the water within which they are immersed. succeeding species have evolved to be flexible and curious to environmental changes in order to adapt. good navigation skills between points of interest suggest the tune of earths geomagnetic spatial positioning; a field that manifests at the cellular level. some of nature’s best navigators are an anadromous fish that spawns in freshwater after migrating from the sea, salmon. #fishsense #fishscience #sandbarsharks #oneoceandiving photo @jaywiththecamera #hawaiisharkcount #internationalsharkproject #haleiwasharks

oneoceanresearch Galapagos shark #cgalapagensis are known to be largest in hawaiian waters. perhaps that is what it took for these indopacific voyagers to make it to the hawaiian archipelago in the first place. the galapagos shark is common along oceanic islands in the pacific; galápagos islands (for which they are named), revillagigedos islands, islands of cocos, and the hawaiian archipelago. unlike the fore mentioned coastal islands, hawai’i truly encompasses over 1500 miles of reef islands and atolls that extends to kure and midway in the northwest #pmnm #nwhi #islandpassage #galaps photo @nate_smith_ #helpsavesharks @oneoceandiving |follow our friend @oneoceansharks to meet individuals like these pictured here: #gillpocket moving up out of the way queen #msaloha parading her leaf πŸ‚ #sharkid

oneoceanresearch The cartilage base skeleton of a shark allows for heavy bending turns to more readily flow with fluid mobility of water. cartilage is also lighter, less dense, than bone making it easier to travel up and down in the density made up of increasing water pressure. even with these advantages cartilage is sturdy enough framework to keep torpedo like structure of a shark propelled forward by tail undulations and steering to part the viscosity of water a marine environment. #sandbarsharks #carcharhinusplumbeus photo by @salt.n.skate out with #oneoceandiving #saveoursharks #saveshark #sharksonsand #noplasticstraws #strawban #styroban

Taking drops πŸ’§πŸ¦ˆπŸ’₯ @silkymerman video ft @shnooz. building personal comfort in the water & with the water as a force larger than you helps humans relate to sharks. to take a drop, gain their attention for even a moment can light a fire inside #naturalhigh #sharkaddiction but more importantly their eyes cut deep with respect. they will look back at you if they choose to and the more natural you blend into their environment the more likely you are to gain an intimate experience 😎⚑️ #studysharks #beashark #learnthewater #lovetheocean #savethesea #sharks #sharkdive #pelagicdive

oneoceanresearch A little late;) but official congratulations to our @universityofhawaii graduate in #predatorscience focus @tracyann_saltygirl (pictured here with #galapagossharks carcharhinus galapagensis) of @waterinspired x @oneoceanglobal πŸ€—πŸΊπŸ¦…πŸ¦ˆπŸ…πŸ» tracy has been studying shark for years and always brings it back to importance of their ecological role. connectivity of the natural world can seem very obvious to many people (science) but much of the modern world remains #disconnected. predators are actually responsible for the reproductive success of their prey groups by managing their populations from overflow, directing genetic progression, steering biodiversity, and even maintaining health and balance of the environment!. #learnmore #gotoschool #studysharks #studypredators #getschooled #getlearned #getsmart #swimwithsharks dm @tracyann_saltygirl for more on predators, ecology, #trophiccascade, #biomagnification, &more or throw her a sweet congratulations for sticking in school, work, training, family, pet floofs, friends, volunteer, and more. #gogettah πŸ‘πŸΎπŸ‘πŸΎ

oneoceanresearch From our amigos de @keoki_delmar world wide there are estimated to be around 30,000 tiger sharks left. in hawaii alone between 1959 and 1976, 4,668 tiger sharks were culled in an effort to protect the tourism industry. in the 1992 cull over 500 tiger sharks were also killed. the most recent cull in australia was in 2014, where 175 sharks were killed, 50 of those tigers were over 9ft. these statistics don’t even include the thousands that die daily at the hands of commercial fishing. sharks have been around for over 450 million years. who are we to decide who lives and who dies? help save sharks by speaking up for them. visit www.change.org/p/one-ocean-diving-protect-sharks-and-rays-in-hawaiian-waters and sign the petition put together by the folks @oneoceanconservation and @keiko_conservation. contact local government in your area and get involved. ~ 🦈 πŸ“· @hkffishguy ~ en todo el mundo se estima que quedan alrededor de 30,000 tiburones tigre. solo en hawai, entre 1959 y 1976, se mataron 4,668 tiburones tigre en un esfuerzo para proteger la industria turística. en la matanza de 1992, también murieron más de 500 tiburones tigre. la matanza más reciente fue en australia en 2014, donde murieron 175 tiburones, 50 de esos tigres median más de 3 metros. estas estadísticas no incluyen los miles de tiburones que mueren cada día a mano del ser humano. los tiburones han existido por más de 450 millones de años. ¿quiénes somos nosotros para decidir quién vive y quién muere? •••••••••••••••••••••••••••••••••••••••••••• . . . #keokidelmar#conservation#protectocean#oceanminded#ocean#oceantherapy#oceanconservation#marinelife#underwaterphotography#underwaterphoto#underwaterworld#underwaterlife#uwphotography#uwphoto#diving#freedive#conservationphotography#wildlifephotography#wildlifephotographer#savetheocean#oceanography#oceano#oceanopacifico#mar#conservación#educacionambiental#cuidemoselplaneta#vidamarina#tigershark#galeocerdocuvier

oneoceanresearch Determining gender #sexing marine animals can be difficult because their position in the column. even with large 40-50ft specimen as these southpacific humpback whale dancing with @oceanramsey in tonga captured by sharky @juansharks. the male have a closer positioning of the urogenital opening to the umbilicus.(as pictured in this photo and our post from yesterday). the female carries mammary slits and a hemispherical lobe between the genitalia. interestingly male whales also carry a physical bone to aid with mating #whaleboner #humpbackwhale the reason we find this to be so fascinating is that many whale watchers glance at pairs of whales and expect them to be male and female associations but there are often female nurses, calves from last season, buddy males and many other social associations 😁🐳🐳 #whalebuddies #whalepairs #megapteranovaeangliae #tonga #divetravel #whalehellothere #humpbackfriday

oneoceanresearch ‘parallel swimming’ by competitive adult male galapagos. #carcharhinusgalapagensis this is deemed an agonistic display as an observed claim for dominance over another shark(s) achieving social status and therefore preferential approach, position, ownership over sought territory, mate, point of interest. this type of sizing up can be easily resolved or lead to further displays that can escalate in speed, body positioning and assertive claim. competitive behavior is rarely associated between people and shark because people are foreign to the sharks environment and many humans that make it there are regarded with respect as equal predator. of course this depends largely on the way the human handles themselves in foreign space recognizing the water is not rightfully theirs to claim beyond a personal space bubble. diving with @saltyblackphotography @oneoceandiving #helpsavesharks #oneocean

oneoceanresearch The cycle of a new north pacific humpback whale #megapteranovaeangliae calf is approximately a 3year endeavor. copulation occurs in winter along the shores of the hawaiian archipelago. after 10 months of gestation the cow (adult female)will return to hawai’i to deliver. this calf will then stay by mother’s side for one more year until back to hawai’i they become independently socializing yearlings. • typically one calf is born per mature female every 1-3 years. this is because after birth the growing calf is also learning songs and migration patterns. newborn at 1ton these quickly growing babies are drinking up to 100gal milk per day to bulk up for their first journey over 2000mi north to the quickly cooling and nutrient rich waters around aleutian islands of alaska. • photo by @kokocousteau @oneoceaninspired #savethewhales • how to submit testimony for sb3055: email: aentestimony@capitol.hawaii.gov with the subject “support for sb3055 relating to cetaceans” or submit online at captiol.hawaii.gov (search sb3055). this bill will prohibit any transfers or imports of captive cetaceans for breeding and entertainment! if you are in hawaii please come to the capitol at 2:30pm to join us and testify in person! #keikoconservation #animalrightshawaii #arh #emptythetankshawaii #oneoceaninspired #oneoceanconservation please visit keikoconservation.org

oneoceanresearch Graced by the presence of an ‘iwa bird for which the harbor town of haleiwa was named. photo by @sharkysophie on board #manokai. #iwa are more globally known as the greater frigate birds. adult males are all black with a red inflatable throat pouch 🎈 and the females carry a white feathered breastplate. seabirds contribute to the biodiversity of both coastal and pelagic ecosystems. locally we have been noticing a heavy decline in the number of iwa probably following the destruction of their hatching sites along ali’i beach park reserved for native hawaiian royalty. frigates have the ability to cruise for prolonged flights up to days at a time riding the shifting temperature of low pressure thermals and scanning for smaller birds to steal their meals. #oneoceandiving #seabirds #biodiversity

oneoceanresearch @mermaid_kayleigh passing over the top of #nikkigirl last summer photo by @oceanramsey. #helpsavesharks this particular shark and others that accept touch are still independent beings. one touch, one interaction, one day, one shark does not define experiences and generalizations for all sharks or even a single species. learning to see animals (particularly sharks;) as calculated, living, surviving, immaculate creatures requires patience and understanding. animals are very different from humans and they do not look act think or interact in the same way. sharks are becoming popular culture and we want to share and steer that with live experience in a guided pelagic setting meeting wild sharks on their terms in open ocean environment. learn more about ongoing research projects, pelagic life, seabirds whales fish weather invertebrates sharks and more@oneoceandiving #scientificsharks #sharkdive #livelikenatgeo #protecthawaiiansharks

oneoceanresearch Blue sharks #prionaceglauca are one of the most heavily fished species by hawaii longline fisheries. they occur naturally to the north of the island archipelago for much of their life. pups are deposited much further north into cold productive waters where they stay until maturity moving south to the waters just north of the islands. as adults much of their life is spent segregated males from females. because many populations of sharks use vastly different parts of the ocean (varying depth, temperature, food source etc) it is important to remember that even specifically targeted fishery zones effect a much wider habitat space. these types of lessons in connectivity define the importance of sustainable options for fishing like using the growing seafood watch app, supporting local and catching fish seasonally at appropriate catch rates. apex predators have an important role for the entire ecosystem and can sway the health and biodiversity of the regions over which they roam. #biodiversity #evolution #science #apexpredators #blueshark #hawaiisharkcount photo by @saltybluegypsy @charnipeat #nz πŸ˜˜πŸ’™πŸ¦ˆ
