#sharkidwave calling for his ladies 😘 wave is a male galapagos who was frequenting our aggregate site in the early spring but it seems he has since been traveling abroad. read more about sharks and their claspers below via @oneoceanresearch
・・・
footage of male galapagos #wave stretching his #claspers and possibly releasing #pheromones. the claspers are true offshoot appendages from the pelvic fins used by the male in #copulation. there are 2 theoretically as a "backup" set although in truth to follow the parallel streamlined nature of the shark. early sharks did not all have claspers but a single placoid scale at the tip of each has been traced a majority of the distance thru fossil records. (dermal denticles and teeth are some of the best fossils of sharks). ps most of them are rightys;) #clasperpop #stretchem #flexon #swoll #sharkboner #pelvicfins #maledisplay #sharkporn #galapagosshark #sharkid #oneoceansharks @forrest.in.focus @sharkysophie @seajewl online book on the evolution of claspers https://books.google.com/books?hl=en&lr=&id=6gk5aaaaiaaj&oi=fnd&pg=pa221&dq=claspers&ots=krjphs1ia3&sig=4bap1sn3xzwn-zq6w0arziughks#v=onepage&q=claspers&f=false

#sharkidnubs getting told off by a sassy female yesterday! mr nubs has a shortened, rounded right pectoral fin. you can see the contrast between his two pectoral fins in this photo. he’s also got a slightly agape jaw, similar to miss snooty famous lemon shark in florida 😁 nubs is a confident older male galapagos that calmly holds his dominant position throughout the dive.

#sharkidmrstitchy getting up close and personal with safety diver and @oneoceanhawaii baws @ge_keoni fins! mr. stitchy, a male sandbar, has got black “liverspots” along his body as well as raised white bumps, documented on a few sandbars that have come by. wish we could say it was adolescent acne but seems to be possible skin disease, fungus and/or ectoparasite. there is limited knowledge on skin diseases on sharks- wish we could get some biopsies! #hawaiisharkcount

The beautiful roxy showing off to @juansharks camera back in 2016 💙 tiger #sharkidroxy is best known for her broken jaw, most likely caused fighting on a long line from fishermen. although at first glance it makes her look menacing, her true disposition(calm and cautious) shows- not something i would be if i came across the same species that caused my broken jaw and the deaths of millions of my kind. another sign it’s roxy is the satellite tag on her dorsal, an invaluable tool used to track and learn more about tiger sharks around the hawaiian islands by @himb_soest

#sharkidkyliehooks young female galapagos last spotted in february this year but she was a regular last year, hanging out with the other juvenile female galaps like skinny michelle, kenny girl, and queeny but also seemed with bffls with male sandbar mr. itchy, hanging together on almost 20 dives. it is interesting to see the different shark ids that seem to overlap frequently throughout the year. 💙

Our male sandbar #sharkidscoopfin cruising on the bottom of this frame. carcharhinus plumbeus is one of the most fished shark in atlantic waters, primarily prized by their tall dorsal fins which is one of their most defining characteristics. sandbars are found along the coasts of many continents with hawaii being their most isolated location.

There’s more to shark identification than just scarring! read below for more by @mayasantangelo 💙
・・・
meet sad face. sad face is a ~12ft male great white shark aptly named after a set of scars on his left flank that look just like, well, a sad face. as one of more than 200 white sharks individually profiled in the @marinecsiorg guadalupe photo id guide, these special marks have been useful to identify sad face when observing the sharks on cage dives. however, with amazing shark healing capabilities, his characteristic sad face is now healed to barely noticeable. so without this mark, how can i tell if this is the real sad face? and what if he only shows off his right side like he did in this photo?! lucky for great whites, the countershading boundary pattern (where the grey meets the white) that runs along the length of their body is unique to each shark. while scratches and scars are only temporary, this pattern is just like a fingerprint that can be used to profile each shark for their entire life. this fingerprint is therefore useful not only for me to be certain this is sad face, it means that anyone that dives with great white sharks can use their photos to help researchers document and understand what sharks are visiting guadalupe island. woohoo (citizen) science!

Stunning shot by @camgrantphotography of #sharkidmauka, one of our og #ladysharks, nosing her way through a school of opelu, probably scanning for any injured or weak fish. meanwhile the #opelu are relying on their lateral line to give mauka some space in case she does decide to make one of them a snack. 😉 mauka means “towards the mountain” for the mountain-like shape of her dorsal fin. this female galapagos is one of our dominant females when she decides to grace us with her presence! last seen late september this year 💙 #hawaiisharkcount #hawaiisharks

#sharkidviolet cruising the reef at tiger alley. 🐯 violet is a sweet female tiger that only let @juansharks in close enough to take this photo and a couple more. one of her most distinguishing marks is the split in her right pectoral fin by you can see in a previous post. she also sports quite the array of mating and possibly competitive bite scars over her body. hope to see her again someday soon! 💜 #tigershark #hawaiisharkcount
