A marine conservationist has revealed the secrets of one of the ocean’s most beautiful but dangerous creatures.

The mysterious blue sea dragons use venom taken from Portugese man o’ war jellyfish and use it to kill their prey.

Julian Obayd, 21 – the self-styled blue dragon hunter- is a marine biology student from Queensland, Australia, who became facinated by the exotic killers.

Videos uploaded by the student show how the dragons get their venom from eating chunks of the jellyfish.

And because it is concentrated in their body, the venon becomes even mopre powerful.

One video on his TikTok account – which has 378 000 followers – shows dragons surrounding a Portugese man o’ war as they feed on it.

Another viral video called, ‘Failed Rescuer Mission’, shows him rescuing a bucketful of blue dragons from a beach on North Stradbroke Island, Queensland.

But as he returns them to the sea the waves bring them back to sting him.

The wildlife volunteer explains, “So today I stuffed up big time. I came to the beach and I wasn’t expecting to see blue dragons but I ended up finding a lot so I had to make this little homemade bucket thing I bought from the shops and by this point I’d found like, heaps.

“And this is sort of where I stuffed up right here, I walked them to the beach to pour them out and they all came back to me, and my stomach is stuffed.”

One user commented, “forbidden shark gummies”, while another wrote, “aren’t they like, really venomous?”

In an interview with Newsflash, Julian explained that the blue dragon (Glaucus atlanticus) is, “a highly venomous sea slug that uses venom collected from their diet of blue bottles.

He said: “They release it from their ceratas (those little tentacle things).

“I call it a Pokémon because of the intriguing shape and vibrant colours.”

A second video that shows a blue dragon eating a blue bottle or man o’ war (Physalia physalis) received reactions like, “deadliest fish tank ever” and “world’s deadliest soup.”

When asked what inspires him to share these videos, Julian said: “I really would like people to see and experience the beauty I have been so luckily to have grown up with.’

He added: “Steve Irwin was a big impact on my life growing up, he grew up in Queensland too. There’s a lot people haven’t seen from our oceans.”

Blue dragons are found in tropical oceans around the world and feed on other dangerous sea creatures before storing their venom.

The sea slugs are best admired from afar as their stings can result in acute allergic contact dermatitis as well as post-inflammatory hyperpigmentation along with nausea, vomiting and intense pain.
