Portuguese Man O’War – Did You Know…

… That the Portuguese Man O’War is technically not a jellyfish?

Anyone unfamiliar with the biology of the venomous Portuguese man-of-war would likely mistake it for a jellyfish. Not only is it not a jellyfish, it’s not even an “it,” but a “they.” The Portuguese man-of-war is a siphonophore, an animal made up of a colony of organisms working together.

The man-of-war comprises four separate polyps. It gets its name from the uppermost polyp, a gas-filled bladder, or pneumatophore, which sits above the water and somewhat resembles an old warship at full sail. Man-of-wars are also known as bluebottles for the purple-blue color of their pneumatophores.

The tentacles are the man-of-war’s second organism. These long, thin tendrils can extend 165 feet (50 meters) in length below the surface, although 30 feet (10 meters) is more the average. They are covered in venom-filled nematocysts used to paralyze and kill fish and other small creatures. For humans, a man-of-war sting is excruciatingly painful, but rarely deadly. But beware—even dead man-of-wars washed up on shore can deliver a sting.

Muscles in the tentacles draw prey up to a polyp containing the gastrozooids or digestive organisms. A fourth polyp contains the reproductive organisms.

Man-of-wars are found, sometimes in groups of 1,000 or more, floating in warm waters throughout the world’s oceans. They have no independent means of propulsion and either drift on the currents or catch the wind with their pneumatophores. To avoid threats on the surface, they can deflate their air bags and briefly submerge.

Blogger Party And A Happy Dance

jelly dance

Doing a little Happy Dance over here and somehow can’t stop thinking of a picture of a jelly fish I recently took. While watching I felt like it was dancing for me… I know, it takes some imagination to see it. Maybe you should have been there too…

Now let the jelly be a jelly… Most importantly: I just want to shout out a huge THANK YOU ALL!!!

Thank you all so much for your support, for your visits, the likes, the comments, for inspiring me and for teaching me heaps of stuff! Today I reached the amazing number of 100’000 views!

I thought I might be able to catch the 100’000th view but headed over to one of your posts to read at 99’992 views and suddenly I was at 100’006… Oh well…

What a number, right?!

When I started the blog I was hoping to find one or two souls somewhere out there who would like to read what I’m writing about. It’s 1 1/3 year since more or less and I simply feel humbled.

I have all in all (Facebook and Twitter included) just over 1’800 followers. There’s a fantastic core group that I see frequently commentating on my posts. Bloggers I feel I know by now and consider my virtual friends.

And now I really hope you feel like celebrating with me!

Let’s party together!

  • Share the link to your blog in the comments. Maybe with a short introduction? Maybe the link to a favorite post of yours? Up to you…
  • If you like reblog this post so other bloggers can find their way over there and share their link too in order to meet some new “friends”

And then party! Catch up with everyone else who is here today. Say hi and have a friendly conversation. It’s how you meet people, you know.

Thank you all so so much! Now let me continue with my Happy Dance 🙂

SL – Week 22: Transparency

I knew exactly which picture I wanted to post for Silvain Landry’s task of his SL Photo Challenge. But then I started thinking about what the word “Transparency” means. The definition is pretty clear:

1. The condition of being transparent.”the transparency of ice”
2. A positive transparent photograph printed on transparent plastic or glass, able to be viewed using a slide projector.

But then there’s also a behavioral side to the word.

Openness in communication. Accountability.

So I tried to figure out how to capture that in a picture… How would you picture openness, communication or accountability really? Of course I know there are pictures for it. But how to put the meaning of it really in a picture?

Vision Of A Boxjellyfish – Did You Know…

… That boxjellies have have more advanced vision than their counterparts? The box jellyfish has 24 eyes, two of which are capable of seeing color, and four parallel information processing areas that act in competition, supposedly making it one of the few creatures to have a 360-degree view of its environment.

I know, again about boxjellies. But you know what? I found them so fascinating. Amazing actually. Look how advanced they are? No wonder they have been around for ever…


Jellyfish II – Did You Know…

… That some jellyfish have millions of very small stinging cells in their tentacles called nematocysts. These cells are used to capture food by injecting toxin into the prey. When we are stung it hurts because the toxin goes through our skin. And in some cases this can be lethal…

A box jelly can be the size of a grown up man. They are the reason why in Far North Queensland swimming in the ocean without wearing a stinger suit or inside of a stinger net is not recommendable.
