NGC 4676: When Mice Collide

I’m heading back to Chicago for a week in June (9-17). I just booked my tickets! Essentially as soon as I land I’ll be whisked away to a HUGE family party. It’s my grandfather’s something-really-important-th birthday. 80 maybe? It’s also my grandparents’ wedding anniversary.
My birthday is the 14th, my uncle’s birthday is the 16th, and the Red Sox are playing the Cubs the 15th-17th! Even if I don’t end up going to the games, I’d like to spend one of the days in Wrigleyville being a mess.
Oh! and Jenny, The Bloggess, will be at the Printer’s Row Lit Fest promoting her new book. I’m SO there. I already got my ticket.
I miss Chicago. I miss my family. So excited to spend a decent chunk of time there soon!

Portuguese Man-o-war (Physalia physalis)
by National Geo staff
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…

I love these. Mainly because the name is so fun to say.
