Protecting sharks and working with the people and places they depend on.

Tiger sharks (Galeocerdo cuvier) are more than just apex predators — they’re vital storytellers of the Pacific.

Because they can swim vast distances along coastlines and even across the Pacific, tiger sharks also help us uncover how marine life connects across island nations and ocean corridors.

We removed some tangled shark fishing gear with j hooks (a no-no) that was wrapped in one of Niue’s FADs. This likely drifted from the open ocean as the Niuean fishers didn’t recognize the gear and use circle hooks (safer for sharks) to fish for tunas.

Here’s how thresher sharks whip their tails back and forth
A new study breaks down the biomechanics of one of the marine world’s most unusual hunting behaviors. Thresher sharks have one of the strangest body plans of any fish, with almost half their body c…

The first tiger shark (Galeocerdo cuvier) ever tagged in the Cook Islands was released off Aitutaki. We’re still waiting for her tag to pop off and reveal her journey.

We tagged it, so what? Tags reveal where sharks travel and when, giving us a glimpse into their secret lives. These insights guide better protections (and make cool squiggly lines on maps). We are so close to funding the next tag. Let’s goooo! Invite your friends!

How do we tag sharks? Our team uses standardized, ethical methods to attach satellite tags that transmit movement data. You fund the tags and we’ll fund the time to deploy them. Join our Sharktober Tag Team!

Tag, you’re it! For this month, (Sharktober, of course), the Sharks Pacific Tag Team will donate to fund satellite tags to study shark movements in the Pacific Islands. Donors receive Tag Team swag, tracking access, and entry into a name-a-shark contest. Donate today. Link in bio. Tag a friend!

Happy World Manta Day!

Predicted in 2009 by Dr. Andrea Marshall, but formally recognized & described in 2025, Mobula yarae became the third manta ray species. What are the scientific names for the other two species?

A white shark (Carcharodon carcharias) near Isla Guadalupe, MX.

Fun fact: Research shows their brains are dominated by huge olfactory bulbs, among the largest of any shark, letting them track prey and navigate by scent across vast distances.

Niue is often called “The Rock of Polynesia”—a raised coral island surrounded by some of the clearest water on Earth. With no rivers to carry sediment into the sea, visibility here can be up to 80m (basically infinity). We love doing our work here.

Ocellated eagle rays (Aetobatus ocellatus) flying through open space.

Fun fact: They use electroreception to locate buried mollusks in the sand, sometimes crushing shells with their plate-like teeth.

An oceanic whitetip (Carcharhinus longimanus) cruises through the blue waters of the Pacific.

Fact: Once considered one of the most common pelagic sharks, due to overfishing (both targeted & bycatch) their populations have drastically declined and they are now Critically Endangered.

Silky sharks, affectionately known as silkies (Carcharhinus falciformis) aggregating in the Southern Line Islands.

Fun fact: They can detect low-frequency sounds from distressed prey—making them extremely efficient open-ocean hunters.

Can blue sharks change color? 🦈🌈

Blue sharks might shimmer blue, green, or even gold, thanks to tiny crystals in their skin. These pressure-sensitive structures, found in their tooth-like scales, shift as the shark changes depth, reflecting light in different ways. 🧪

Tawny nurse sharks (Nebrius ferrugineus) waiting for fish scraps on Penrhyn Island.

Fun fact: They use powerful suction to extract prey from narrow crevices. This is among the strongest suction forces recorded in sharks.

Grey reef sharks (Carcharhinus amblyrhynchos) scour the shallows off Palmerston Island.

Fun fact: In some locations, during specific times of the year, they form an unusual “inverted food pyramid” where they outnumber their prey.
