The sharks don’t have legs, but video shows they’ve become pretty good at walking around on the ocean floor with their fins, much like a seal or otter. “They can even walk on land for a bit,” study co-author Mark Erdmann said in a Q&A with his organization, Conservation International.
How many sharks are being tracked?
These are just three of the roughly 70 sharks currently being tracked via small electronic transmitters by OCEARCH, a research organization that collects and shares real-time data through its popular shark-tracking app.
Is Deep Blue tagged?
Researchers managed to affix a tag to Deep Blue during their expedition. The tag is a scientific device that transmits the shark’s depth, location and other data to help researchers better understand the animal’s behavior and movement.
SPOT tags are secured to the shark with plastic bolts and can stay on the shark for up to five years. They use radio transmission to transmit the shark’s location via satellite whenever the shark’s fin breaks the surface during a period in which a satellite is overhead.
What do you do if you catch a tagged shark?
Leave the shark in the water while tagging. Release prohibited species immediately. Do not gaff a shark you plan to release.
How much does a shark tag cost?
These tags cost about $1,500 each and were funded by The Nature Conservancy of Texas. Research institutions have standard procedures for capture, tagging, handling, sampling, and release of animals, including sharks. “Once a shark is caught, we work very quickly,” says Hueter.
Is it ethical to tag sharks?
No sharks (or other wild animals) should ever be tagged without first gaining ethical approval for the research. If you go ahead and do this anyway, you may be breaking the law. If you can get to this stage, now it’s time to start tagging sharks!

Are sharks coming closer to shore?
According to experts, sharks swimming closer to urban shores is a sign of both environmental progress and climate change. Typically urban areas have been too polluted and overfished for sharks to thrive.
How close can a shark come to shore?
According to most statistics, sharks can come as close as 100 feet from the coast. The Florida Museum of Natural History stated in this context that most shark attacks take place in 6 to 10 feet of water.

What is the biggest shark ever tagged?

Is there a shark bigger than Deep Blue?
Marine biologist Michael Domeier also claims to have seen specimens possibly larger than Deep Blue while conducting studies of the great white shark off the coasts of Mexico and California. And there are almost certainly larger sharks no one has ever seen or documented before lurking out there.
