In our RSO studies, we are starting from the simplest animals and this past week we’ve learned about cnidaria and worms. We also added our own sponge study. The animals start off extremely simple, and slowly they are getting more complex. The most primitive animals have even been thought to be plants until scientists discovered certain characteristics that make them true animals.

Satori and I checked these books out at the library. I was giddy with excitement to discover all the different books they had on worms and sponges and stuff. I just grabbed a few of each phylum and hoped for the best. I was pretty worried Satori wouldn’t enjoy reading over a dozen books on simple creatures, but I was wrong. We had an absolute blast yesterday and didn’t even get to any other subjects!

Each book gave us different and fascinating knowledge about sponges, cnidaria and worms. Satori also found a $5 bill on the ground at the store, and when she tried handing it to the cash register lady, she was told “finders-keepers”. So we headed to our local nature store and she picked out a $5 toy – a jellyfish!

Anyway, Satori was absolutely delighted with her new sea jelly. She carried it in her hands all day yesterday. I doubted that it would float, but today we discovered that it does! Introducing Jella! (of course her new animal has to have a name)

From our books we learned that the outer things are stinging tentacles and then the feeding arms bring their food to their mouth. They are carnivorous. They cannot go after their prey, they just float along and whatever gets stuck in their tentacles is their food. Sea jellies are 90% water. We actually are going to call the jellyfish a sea jelly from now on, as fish have backbones and sea jellies do not. They don’t even have brains.

She’s now taking a bath with Jella, her lucky favorite new toy. Move over Ariel the mermaid, make room for Jella the Sea Jelly!

We were also surprised to learn that the Portuguese Man-o-war is not a jellyfish, but it is a relative in the Cnidaria family. The Man-o-war is actually a colony of polyps living together. For those of you living near the ocean, are these things common to see?  I see one of these washed up on the shore a few times now. They’re so pretty.

Daddy made it back from his two-week Mexico trip at 1am this morning. Satori begged for him to wake up early. She then proceeded to teach him all she knew about Sea Jellies and Men-o-war (plural). I woke up to a list of everything David learned about sea jellies and friends. 🙂

Satori just got done with her bath and she quickly dressed and ran to yank Daddy out of his office. She roped him into reading her sea anemone book. I’m listening to him read aloud now. 🙂
