Live Shark Tracking
SRF and our collaborators are tracking sharks around the world using advanced satellite technology. This interactive map lets you follow their movements in near-real time, offering unique insights into shark behavior, migration, and conservation. Click on a shark in the right menu to track it.
FAQs
What type of tags do you use?
We use satellite-linked transmitting tags, which are mounted on the shark’s dorsal fin and are designed to transmit a signal to Argos satellites whenever the fin breaks the surface of the water. To successfully obtain a location, an Argos satellite must be overhead, within range of the tag, and the tag must remain out of the water long enough to send multiple transmissions to the satellite. Because these tags rely on brief surfacing events, data quality and frequency can vary depending on species, behavior, and environmental conditions.
Why are some of the locations on land?
The satellite-linked tags we use transmit a signal to Argos satellites when the shark’s dorsal fin breaks the surface. To determine the shark’s position, the fin must stay above water long enough for the tag to send multiple transmissions. The more transmissions received, the more accurate the location. However, when fewer signals are received—often due to brief surfacing—the resulting position may have lower spatial accuracy. This can cause some points, especially those near coastlines, to appear incorrectly on land, even though the shark is still in the water.
Why haven’t some sharks provided recent locations?
The tags we use only transmit when a shark’s dorsal fin breaks the surface and connects with a satellite. If the shark remains submerged or if a satellite is absent when the shark’s fin surfaces, then no position is generated. Sharks can go for long periods of time without surfacing, which can generate some large gaps in the tracks.
Why are there large gaps in tracking data?
This can happen when a shark doesn’t surface for extended periods or if satellite coverage is limited. Tag fouling, water conditions, and shark behavior can all create data gaps.
Why have some sharks stopped transmitting?
Possible reasons include: the tag’s battery running out, detachment or damage to the tag, the shark no longer surfacing, or the shark has died. Even short-term data offers valuable insight into shark movement.
How long do the tags last?
The tags we use typically function for 6 months to 2 years, depending on battery life, environmental conditions, and how often the shark surfaces.
How does this tracking help shark conservation?
The data we collect supports research on shark migration, habitat use, and threats like overfishing and environmental change. It helps scientists, policymakers, and conservationists make informed decisions to protect these animals.
What is the ‘Adopt a Shark’ program?
For a $3,000 donation, you can adopt a shark, give it a name, and receive a private tracking link to follow its journey. Your support directly funds research and conservation.
Can I share my adopted shark’s tracking link?
Yes! You’re encouraged to share it with friends, family, classrooms, or on social media to help raise awareness for shark conservation.
