You are also in danger. Compared to some ocean beasts, humans are much like china dolls. A small shark can bite cause life-threatening injury. A large shark can take your limbs off or kill you with one well-placed bite. A bikini or a neoprene wetsuit is not going to protect you. Leave them alone2.
Another serious issue is that humans carry germs. The bacteria on your hands and oils on your skin can be toxic to various marine life. Additionally, there are indications that human viruses can be passed to and harm coral reefs3.
Not only can you be toxic to marine animals, but they can be venomous to you. A strike from a cone shell is more toxic than most snakes and can kill you in minutes. Blue ringed octopi and stonefish are also incredibly deadly4.
Touching and especially feeding wildlife can cause them to abandon their natural instincts to avoid humans and boats, putting them at risk of infections, boat strikes, and other human dangers. Additionally, this can cause species to become aggressive after they learn people = food. This also damages their ability to find food naturally5.
Frequently asked questions
Here are a few questions people often ask me about their Great Barrier Reef experiences.
What if it's for research?
Research interactions are conducted under rigorous ethics laws by trained scientists or students. These interactions can include tagging and are done to further knowledge. These are not for fun and are limited to the minimum possible interaction.
What if it comes up to me and touches me?
If it wants to touch you, it's allowed to, and that is reasonably acceptable. However, understand this is not a normal behaviour, and you should not encourage it. If an animal comes up to you, you should not interact with it if possible. That being said, don't shove it away either. That's bad, too. Try to get away yourself.
But you have animal pics on your social media, Kelly.
I do have animal pics online. Why? I am working towards a Master of Science, majoring in marine biology, after completing an undergrad degree in the same field. I have training in marine animal handling and husbandry, which is conducted under supervision by professionals. Any pictures on my social media were taken during supervised research.
Additionally, I volunteer weekly at a wildlife sanctuary and regularly interact with animals there under supervision by trained professionals. There are some photographs from this, as well. I have also had an exceptionally rare instance of a sea turtle approaching me on the reef. I did not instigate this nor did I try to touch it, but backed away until I hit the reef itself. At no point did it touch me, nor did I touch it.
I have photos online because this field is my life, not for the likes.
