Greater Blue-ringed Octopus (Hapalochlaena lunulata)

 

The Blue Ringed octopus has 3 hearts pumping blue blood, food digestion occurs in the brain and it contains enough venom to kill 26 humans in minutes!

But maybe the craziest fact of all is that this clever little badass doesn’t even produce its own venom. Like many other sea creatures, the blue ring utilises a symbiotic relationship with other organisms.

In the Blue Ring’s salivary glands live many toxin secreting bacteria, these neurotoxins paralyse any animal unlucky enough to be injected.

When hunting, the Blue Ring descends on its prey using its beak to create a puncture wound which it then spits saliva into; quickly paralysing the victim and making for a fuss free meal.

Despite this, the Blue Ringed octopus has only caused 3 recorded deaths worldwide. These beautiful creatures are very shy and are fascinating to observe. Like all marine creatures, show them respect and you’ll be rewarded with a breathtaking experience, and often a flamboyant display.

Harlequin Shrimp (Hymenocera picta)

Harlequin Shrimp , if observed, are beautiful and graceful creatures. You may see them swaying back and forth peacefully waving their paddle like claws as if dancing. They form monogamous pairs, usually spending their entire life with the same partner. I know what you’re thinking, ‘naaaw what sweet, lovely little organisms’, in thinking this you would be wrong!

These unique little shrimp are vicious, calculated predators. Not only do they work together to capture their prey, but they also abduct it and drag it back to their lair where they keep it alive long enough to devour it entirely, which can take up to a week!

Although this is grizzly behaviour indeed, you must admire the inventive tactics employed by the Harlequin Shrimp to get what it wants most, starfish.

Harlequin Shrimp eat starfish exclusively, they’ve even been known to take on the infamous crown of Thorns Starfish. So how do they manage such a feat when a starfish can be up to 100 times the weight of these tiny hunters?
Working as a team, one shrimp snips suction-tube feet from each arm of its prey. Meanwhile, it’s mate gradually pulls the Sea Star over onto its back. Once that’s accomplished, the pair drag their hapless victim off to a preferred dining spot, typically under a rocky ledge or coral head.

Harlequin Shrimp although brutal killers are truly amazing, rare and unique animals and like many other marine organisms they are under threat from human impacts. They suffer as a result of coral reef damage and the Aquarium trade. If you want to keep seeing amazing critters like these guys in their natural habitat then help us care for our oceans, and don’t buy pets caught from the wild.

The Completed Conservation Shed

WE STARTED FROM THE BOTTOM, NOW WE’RE HERE!

We are so excited to announce that our brand new Conservation Shed is complete!!!

Trash bottles
Plastic bottles wash up on the beach on every tide

For those of you who saw our previous post showing our creation in progress here’s a before and after shot that’ll knock your socks off. This pile of potentially harmful waste has been transformed into a quirky delightful little shed. Never again shall our vital conservation materials be ruined by the rain

Now they’ve been transformed into the walls of our conservation shed.

All the hours of filling bottles with sand was worth it and we want to thank every single person who helped out.
