Holy mackerel these guys are fast! So fast, in fact, that I am not actually sure that they were mackerel. Anyone wanna venture a guess as towhead they are ? Seen outside #smithsreef #snorkel #snorkelling #snorkelaroundtheworld

Our team has shown that management of breast implant associated lymphomas is driven by peer-reviewed science. The management of breast implant illness? Not so much. @aestheticsurgeryjournal_asj @ayha9074 @davidchi10 @grace.c.keane #breastaugmentation #BreastAugmentationRevision #

Ocean triggerfish - check out its swaying swimming style in the current. I could not catch or keep up! with Dive Provo #frenchcay #scuba #scubadiving #scubadive #scubadiver #scubalife #scubadiverslife #scubadivers #scubadiverlife #scubaphoto

Eagle rays have a shovel-shaped snout enabling them to scoop up ocean bottom dwellers - their favorite meal! Yes the spines on their tails are venomous but they are not a threat to people. Just don't touch them! #smithsreef #snorkel #snorkelling #snorkelaroundtheworld

School of juvenile snapper. Yellow snapper tend to spawn at reef's edge in mid-summer. As such, we saw a lot of these guys. #snorkel #snorkelling #snorkelaroundtheworld

Green turtles are the largest hard-shelled turtle species and the second largest turtle species overall. They are sometimes skittish, or in this case, not so much. But never touch or handle one. #smithsreef #snorkel #snorkelling #snorkelaroundtheworld

Needle fish swim at the surface. They are attracted to bright lights at night and have been measured up to 38 mph leaping out of the water. An average swimmer like me could not keep up! #smithsreef #snorkel #snorkelling #snorkelaroundtheworld

Porcupine fish has long spines that lay flat on the body. Slightly different than a balloonfish or a spotting burrfish. Cute, but has tetrodotoxin in its skin, eyes, and organs an agent that is 1200 times more potent than cyanide. Look but don't touch I always say! #snorkel #snor

Scientists can distinguish and track eagle rays by analyzing their spot patterns. Makes sense since they don't have fingerprints! #scuba #turksandcaicos

Balloonfish have longer external spines than other puffer and porcupine fish. They have no spots on their fins and their eyes can be an eerie blue color. #smithsreef #snorkel #snorkelling #snorkelaroundtheworld

A school of Caribbean reef squid enjoying the current and protection from the reef - amazing colors and propulsion from these little critters #snorkel #snorkelling #snorkelaroundtheworld

Into the #lions den - at least 7 lion fish with venomous spines - not native the Caribbean, only with some coaxing are they now developing some natural predators (shark, barracuda, and grouper). #scuba #scubadiving #scubadive #scubadiver #scubalife #scubadiverslife #scubadivers #

#Octopus watches on as a dozen #hermit crabs mill about. Must be like a smorgasbord for it! #snorkel #snorkelling #snorkelaroundtheworld

Unlike most #sharks that use ram ventilation to breathe (circulate water through the mouth and over the girls) and need to move to breathe, these whitecap reef sharks I filmed at Roca Partida of the Socorro Islands are just chilling. Why? They contract "cheek" muscles to circulat

Saltwater fish, like these jacks schooling at #Roca Partida drink large amounts of water daily. The water in their circulatory system is less dense than the sea water, so it exits through their gills by osmosis. They consume seawater to hydrate and actually excrete small amounts

This giant pacific black #mantaray enjoying some belly bubbles from dive master @paolosphere at Socorro island. The large appendages at the front are called "cephalic lobes" and are used in feeding to scoop up tiny #plankton. #funfact #funfacts #funfactfriday #funfactoftheday #sc
