From @juansharks: “this is a photo of me gently redirecting #niki the tiger shark. me and niki go way back and the level of trust that she has with me can be seen with her eye contact as i put my hand on her nose. almost every shark will protect its eyes in close range of anything they think could hurt them. tiger sharks have a nictitating membrane that will go up to protect their eyes and niki rarely uses hers with me. i can’t stress enough that these larger sharks are the one that need protection, not only for the survival of their species but for human safety. these larger sharks have learned through experience what is a food source and what is not a food source, meaning they are less likely to mistake a surfer as a sea turtle or a swimmer as seal. also studies show that these larger sharks push the juveniles out of the territory that they patrol. the juvenile sharks are mostly the ones making mistaken identity bites, trying to figure out things and life. killing the large sharks out of fear in shark culling programs is not the answer for keeping the oceans safe for humans. photo by my braddah @lau_z_foto@jerrettlau diving with @oceanramsey during a @oneoceandiving charter” #savingjaws#savesharks#apexpredatornotmonster
Sharks have been demonised by media since the movie jaws and it has influenced people's opinions and how we interact with sharks. movies like jaws and the shallows depict a monsterous great white that only has an appetite for human flesh, which isn't true (hawkes 2016). in an experiment performed in the bahamas, investigators got in the water with sharks and a container with human blood. when they opened the container the sharks had no reaction to it, which shows they really aren't attracted to human blood. they also did this experiment with barracuda blood and even before opening the container in the water, the sharks swam straight to it (wilkins 2019). because of their reputation as killers, shark are being hunted so much to the point that many species are endangered (fears 2013). stay tuned for @savingjawsmovie swimming by soon!

join the #sharkstoo campaign and win a free pareo or t-shirt (see last photos)
for many years i’ve talked about how people love and care about dolphins, whales, turtles, monk seals, etc but when it comes to the health of those populations and marine ecosystems sharks are also a vital component too, they matter too, they need and deserve protection too. they need your help and voice too. please join in helping sharks to get protection too. use the hashtag #sharkstoo and #sharksmattertoo and #protectsharkstoo
sea cucumbers and many species of fish even have catch/kill limits, there are currently no limits/bans or protection for sharks in hawaii aside from taking their fins.
how to support and get involved with this campaign: -please like and share some of these images or create some of your own and keep using the hashtags
-encourage people to support the hawaii shark bill hb808 for protection of sharks and rays. link to more info in the bio of @waterinspired -encourage people to sign the petition and stay tuned to http://helpsavesharks.org for the next public meeting -its not just hawaii, sharks everywhere need your help, please spread this message and help people to care about #sharkstoo please encourage others around the world to use this perspective to gain protection for sharks in other parts of the world.
Sharks play such an important role in the ocean, yet their populations are at a serious risk. thankfully, we’re starting to see a change—a change where sharks are becoming more protected. but we still have quite a bit of work to do. please speak up sharks and continue growing as conscious consumers with us. 💙// photo and caption from @shawnheinrichs

the work to protect sharks and other wildlife threatened by trade started back in 1973, when the convention on international trade in endangered species of wild fauna and flora (@cites ) was formed. every 3 years since then member nations and organizations meet at the conference of the parties (cop). proposals are made then to list various wild species on different lists called appendices that either ban (appendix i) or control (appendix ii) their international trade.
the first shark species listed on cites appendix ii were whale sharks (rhincodon typus) and basking sharks (cetorhinus maximus) in 2001, followed by great white sharks in 2004. after that cites parties were unwilling to list more shark species on its appendices for almost a decade.
but after years of data collection and advocacy, the parties took a sharp turn in the right direction and, in the past six years, have listed 9 commercially important shark species on appendix ii. exporting countries now must obtain permits to prove that trade of sharks listed on appendix ii is legal, traceable and not detrimental to the survival of these species.
scalloped hammerheads (sphyrna lewini), smooth hammerheads (s. zygaena), great hammerheads (s. mokarran), oceanic whitetip sharks (carcharhinus longimanus), porbeagle sharks (lamna nasus), silky sharks (c. falciformis), pelagic thresher sharks (alopias pelagicus), bigeye thresher sharks (a. superciliosus) and common thresher sharks (a. vulpinus) are now on that list. we are hopeful to add a few more to that list - stay tuned for how you can help continue #turningthetide for sharks. 🌊🦈 #cites4sharks#worthmorealive#cites#cop18@bluespherefoundation@sealegacy@vulcaninc@thewcs@pewenvironment@sharkconservationfund

scientists from nova southeastern university and the cornell university college of veterinary medicine have successfully mapped the full genome of the white shark (carcharodon carcharias). the results of this incredible study revealed that the white shark’s genome is around 1.5 times the size of the human genome and also exposed significant evolutions in their genes (shivji et al. 2019). among one of the most significant evolutionary changes to the white shark genome was dna sequence changes for increased genome stability. the dna sequence changes were tied to dna repair, dna damage response, and dna damage tolerance, all of which preserve the overall stability of the genes (shivji et al. 2019). when compared to the genome of the whale shark (rhincodon typus), many of these same genomic changes were also observed, leading the team to hypothesize that the evolutionary emphasis on genome stability may be related to the selective pressure of things like long lifespans, large body sizes, large genome sizes, and high repeat content in the genomes (shivji et al. 2019). also present in the white shark genome was evolutionary adaptation for wound healing, which may explain how sharks are so resilient to large wounds and are able to heal quickly (shivji et al. 2019). humans possess a higher amount of genomic instability in their genes which leads to the accumulation of dna damage-causing diseases related to aging and various cancers. although sharks do still get diseases and cancers, their genomic stability may help protect them from developing cancers excessively, a phenomenon that will have to be extensively studied. dr. michael stanhope, who was an integral part of mapping the white shark genome, further stressed that eating sharks will not transfer their genomic stability or wound-healing abilities to you but studying these incredible ‘powers’ could someday lead to the development of treatments and drugs modelled off of how the shark genome works. @savingjawsmovie#savingjawsmovie#savingjaws

please take a few minutes to help save sharks!! hb808 is a bill ban the “purposeful” killing of sharks and rays here in hawaii. sb931 is a bill to restrict commercial aquarium fishing with fine-mesh nets and traps. please go online to capitol.hawaii.gov and submit a testimony in support of hb808 and sb931 before the 24 hour cut off to the upcoming hearings. you can also send an email to email@example.com with the subject line “in support of hb 808”. then just explain why you support this bill & send it! now’s the #timetosavesharks and help #savetheocean 💙🦈

#repost@oneoceanresearch with information the recently observed decline in white shark presence in south africa ・・・
sharks are vital for the health of the ocean but we are only beginning to fully understand how the removal of apex predators can alter the entire ecosystem. documenting and providing evidence for these impacts can be challenging, but a fascinating new study by hammerschlag et al. (2019) @drneilhammer analyzed data from 18 years of standardized monitoring of great white shark abundance patterns and predatory activity at seal island in false bay, south africa and found that while white shark were relatively stable for over a decade sightings began to decline significantly around 2015 reaching an all time low in 2017 and 2018 where white sharks were not detected at all by their surveys for weeks and months at a time.reasons for the decline are unknown, although hypotheses include overfishing, habitat loss, or a shift in their distributional range due to environmental conditions or prey. the absence in white shark presence coincided with unprecedented appearances of seven gill sharks (notorynchus cepedianus) which normally aggregate in kelp beds due to lowered predation risk by white sharks and less competition for prey items shared with white sharks. predators not only directly impact the abundance of prey items, but can also modify their behavior and physiology. it remains to be seen how the seals will behave in the absence of white sharks in the area, and what the community level impacts of not having the seven gill sharks present in the kelp beds will be in the future.

sharks are considered one of the greatest evolutionary success stories. one characteristic that has helped them stand the test of time is their teeth. sharks have a mouth full of teeth split into various rows, with numbers varying between species. when sharks lose a tooth, a tooth from another row will move up and replace it, acting like a conveyor belt (rasch, 2016). shark teeth regenerate continuously in this conveyor-belt manner throughout their whole life. no matter the number of teeth a shark loses, they will continuously grow more (rasch, 2016). this allows sharks to always maintain their powerful bite and be top apex predators. if you ever see shark teeth for sale make sure you opt for fossilized teeth that have fallen out naturally vs fresh bright white teeth which usually come from sharks that were likely harvested within your lifetime for a silly souvenir

What comes to mind when you see this image- fear or fascination? the way a photo is edited, music choice in a video, or message along with a photo can have a tremendous influence on how we perceive the world around us. for a long time the general public has been negatively influenced by the film jaws and reinforced by most of the mainstream media, but saving jaws will take a closer look at the true nature of sharks and how incredible these animals truly are. stay tuned for updates on #savingjawsmovie swimming by soon! 🤙🏽🦈 #apexpredatornotmonster #repost@juansharks
monster or friend? missing halloween this year to finish the last trip to isla guadalupe with high hopes of photographing “deep blue” the biggest white shark ever recorded on video. according to dr hoyos the large reproductive female white sharks visit the island every 3rd year because of a very long gestation period. the last time she was seen was 2014. 🤞we get to see her. with this very slow reproductive rate and a late s****l mature age estimated to start around 20 years old, white sharks need more places like guadalupe were pregnant females can have a protected refuge from fisheries. this 1st photo is what the media wants from sharks. swipe ➡️to see original unedited. far from a monster these animals actually help humans by keeping our oceans ecosystem healthy and alive. with out a health ocean, humans will not be able to habitat this planet. sharks are our friends. sure they make some mistakes every now and then, but they aren’t actively targeting humans for food. yet they should because humans are killing over 100 million sharks a year. we are killing our life support system by bringing sharks to a extinction level. #savethesharks for the next #generation#coexist#cagethefear#apexpredatornotmonster#helpsavesharks#saveourseas#saveourplanet#love#sharks#photooftheday#instagood photo by #juanoliphant using @aquatech_imagingsolutions@xcelwetsuits@cressi1946@guayaki@gopro@north_sails#gobeyond the jaws to see a friend that humans need. diving with @oneoceandiving@oneoceanresearch@oneoceanconservation@oneoceansharks@oneoceanglobal@oneoceanglobal@oceanramsey
