How do shark adoptions work and how much do they cost? Sharks are difficult to track because of where they live and the great distances they travel. So our adoptions work a little different to many others. Instead of adopting one individual shark, you'll be adopting many by helping to fund vital research projects and campaigns. All our adoptions are a one-off payment of £25 for the year. Although you can choose to make an extra donation by selecting a higher tier. ► Click Here, to find out more about all our adoptions.
