The blue-ringed octopus: a beautiful but dangerous creature (Watch Video)



The third in an exciting new series of blogs introducing some of the amazing marine life you can encounter at Magic Resorts in the Philippines…

One of the most popular octopuses that’s high on almost every divers’ bucket lists, is the blue-ringed octopus. The aptly named creature gets its name from the blue rings on its skin. These creatures usually turn out smaller than everyone’s expectations, but don’t underestimate the power of these critters!

Did you know that the blue-ringed octopus is actually one of the most venomous animals in the world? You definitely don’t want to make this creature angry. So how do you know that you have gone too far and annoyed the octopus? This creature will warn you! Usually a dark brown to yellow color with blue patches or rings, it will turn darker and the blue rings will become brighter and brighter! Though usually shy in nature, if they are stepped on or angered, they will bite!

This little octopus produces two types of venom – one for protection and one for hunting. The one for protection is produced by bacteria that live in its salivary glands. The tetrodotoxin it produces is the same deadly toxin that pufferfishes have. Experiments show that one single blue-ringed octopus has enough venom to fatally paralyze 26 adult humans… at the same time! Unfortunately, there is no antivenom yet and treatment requirements include life-support machines such as artificial ventilation.

There is not just one type of blue-ringed octopus though, there are at least 10 different species which can be found in tidal pools and reefs in the Indo-Pacific Ocean.

During the night, these little octopuses will search for food. They tend to hunt for crabs, clams, shrimps, small fish, etc. But they also have to be wary of their predators, mainly eels.

Fun fact: when a blue-ringed octopus loses a tentacle, it will grow back automatically!

Come and dive at Magic Oceans and let the guides show you these docile blue-ringed octopuses in Anda, Bohol. The guides will help you capture that perfect picture, and you can witness how the little octopus goes about its daily life.

Some general facts!

  • Blue-ringed octopuses can have up to 50 – 60 blue rings on their skin.
  • They are roughly 5 – 8 inches in size.
  • The bite of a blue-ringed octopus is usually reported as painless
  • They tend to have a life expectancy of up to 2 years and lay 50-100 eggs when they mate.

Exhibition: Protecting UNESCO Marine World Heritage through scientific research



From now until 30 October, the photo exhibition “Protecting UNESCO Marine World Heritage through scientific research” features 21 photographs at UNESCO Headquarters, Paris, as well as a digital edition.

Exceptional photographs highlight how innovative marine experts and scientists take the pulse of the ocean by exploring ecosystems, studying the movement of species, or revealing the hidden biodiversity of coral reefs. Scientific discoveries are more important than ever for the protection and sustainable conservation of our Marine World Heritage. This memorable exhibition comes ahead of the launch, in 2021, of the United Nations Decade of Ocean Science for Sustainable Development (“Ocean Decade”). The exhibition was jointly developed by UNESCO and the Principality of Monaco.

The 50 marine sites inscribed on the UNESCO World Heritage List, distributed across 37 countries, include a wide variety of habitats as well as rare marine life still largely unknown. Renowned for their unmatched beauty and emblematic biodiversity, these exceptional ecosystems play a leading role in the field of marine conservation. Through scientific field research and innovation, concrete actions to foster global preservation of the ocean are being implemented locally in these unique natural sites all over the world. They are true symbols of hope in a changing ocean.

Since 2017, the Principality of Monaco supports UNESCO to strengthen conservation and scientific understanding of the marine sites inscribed on the World Heritage List. This strategic partnership allows local management teams to benefit from the results obtained during the scientific missions of Monaco Explorations. The partnership also draws international attention to the conservation challenges facing the world’s most iconic ocean sites.

The exhibition invites viewers to take a passionate dive into the heart of the scientific missions led by Monaco Explorations in four marine World Heritage sites: Tubbataha Reefs Natural Park (Philippines), Malpelo Fauna and Flora Sanctuary (Colombia), Rock Islands Southern Lagoon (Palau), and the Lagoons of New Caledonia: Reef Diversity and Associated Ecosystems (France). It is also an opportunity to discover the work of a megafauna census; the study of the resilience of coral reefs and their adaptation in a changing climate; the exploration of the deep sea; and the monitoring of large marine predators through satellite data.

BLUE EARTH – Future Frogmen Podcast Series – Inspiring Hope For Coral Reefs: a conversation with Ken Nedimyer, a CNN Hero for “Defending The Planet”



A series of conservation educational podcasts from Future Frogmen, introduced by Jeff Goodman.

Inspiring Hope For Coral Reefs: a conversation with Ken Nedimyer, a CNN Hero for “Defending The Planet”.

This episode of the Blue Earth Podcast is a conversation with Ken Nedimyer, a CNN Hero for “Defending The Planet”.

It’s a story about a former commercial fisherman who proactively worked with state and federal groups to ensure a sustainable future.

His observations about reefs in jeopardy led to possible ways to save them. He became an innovative coral reef advocate and coral reef nursery innovator, not only in the Florida Keys but around the globe.

Ken moved to Florida as a boy, he fell in love with the ocean and its many creatures. After earning his degree in Biology from Florida Atlantic University, he headed south to the Keys and never looked back.
