Encountering Marine Life

The allure of the underwater realm around Siesta Key isn’t just about the beauty of the coral or the mystery of the wrecks; it’s equally about the magnificent marine life that calls this part of the Gulf of Mexico home.

Do’s and Don’ts of Scuba Diving

As your underwater expedition in Siesta Key draws to a close, it’s essential to ensure that your journey is remembered not just for the wonders you witnessed but also for the respect and care you demonstrated towards the marine environment and fellow divers. Here’s a compilation of the do’s and don’ts to keep in mind as you round off your scuba diving experience.


  • Log Your Dives: Documenting each dive, including depth, duration, and marine life encountered, helps track your experiences and growth as a diver.
  • Stay Hydrated: Post-dive, replenish your body by drinking plenty of water. Proper hydration aids in off-gassing and reduces the risk of decompression sickness.
  • Rinse Your Gear: Saltwater can be corrosive. Ensure you rinse your diving equipment thoroughly in freshwater to extend its lifespan.
  • Share Stories and Photos: Engage with the local diving community, share your experiences, learn from theirs, and contribute to building a tight-knit diving network.
  • Tip Your Guides and Crew: If you had a guided experience, remember to show appreciation to your dive guides and boat crew. Their expertise and assistance play a pivotal role in ensuring your dives go smoothly.


  • Avoid Flying Immediately: It’s recommended to wait at least 18-24 hours after diving before taking a flight to reduce the risk of decompression sickness.
  • Don’t Touch or Harass Marine Life: Always remember the diver’s mantra: “Take only pictures, leave only bubbles.” Interacting or touching marine life can harm them or alter their natural behavior.
  • Avoid Overconsumption of Alcohol: Post-dive, it might be tempting to celebrate with a drink, but excessive alcohol can hinder your body’s ability to off-gas nitrogen efficiently.
  • Don’t Dispose of Waste in the Ocean: Ensure all your trash, especially plastics, are properly disposed of on land. Marine pollution is a pressing concern, and every diver should be a steward of the ocean.
  • Avoid Solo Diving: Even if you’re an experienced diver, always dive with a buddy. The ocean is unpredictable, and it’s crucial to have someone by your side in case of emergencies.
