I think they stay alive for maybe 10-13 yrs.?

10-12 years
Tiger and reef sharks primarily. The bigger sharks in Guam (like the tiger shark) typically stay beyond the coral reef where they hunt larger prey (like turtles). This is where most shark attacks are reported in Guam (though attacks are incredibly rare: a 1 in 11.5 million chance).
Some animals that are still alive today and lived during the Cretaceous period include crocodiles, turtles, and some species of sharks. These creatures have remained largely unchanged in their basic form for millions of years.
