Sponges do not have proper layers of 'skin' or tissue layers. They're really just lumps of cells.
This one's from the Wren's Nest, Dudley, West Midlands, England and is 428 million years old.

All other animals have one (Placozoa) or at least two (Eumetazoa) layers of tissue in the skin, gut lining etc.
Tidgy is a Eumetazoan.

One flagellum is easier to control and uses less energy.
The Obozoa is split into a couple of groups that have the flagellum at the front and is used to pull the organism along and those that have the flagellum at the rear and pushes the cell forward.
Our sperm cells and those of all animals do this as do those of fungi, so we all belong to the Opisthokonta, as do fungi.
It is interesting that we are more closely related to fungi than we or fungi are to amoeba or plants. Molecular analysis and DNA comparisons back this up.
?Is that how we all decided we like a good couch to laze around on depending on how much flagellum we got? ?

Good mornynooning, Roommates! Breakfast.gif

The Eumetozoa contains two groups.
The first is the Radiata which are radially symmetrical and include the weird and extinct Trilobozoa.

and the Cnidarians including jellyfish (here's one of my fossil ones, Essexella asherae from Mazon Creek in Illinois. 309 million years old.

The Cnidaria also include sea anemones and corals.
Here's the coral Grewingkia canadensis from Indiana, 445 million years old.

The other group of Eumetozoa are the Bilateria, bilaterally symmetrical animals.

Good morning/afternoon all.
It's a very wet, windy day here again.
Yesterday's rugby match was very edge of the seat stuff with eventually a 20 -17 win for Wales, but neither Scotland nor Wales played tremendously well with a lot of penalties being thrown away by both sides. The atmosphere in the stadium was brilliant and it's the win that counts, so we're happy in Wales!! We play England next - hoping for the best but fearing the worst but Scotland beat England last weekend, so we may be fine ???
I hope everyone has a good Sunday.

Afternoon, Lyn.
Glad you enjoyed a seat of your pant's game....
The Super Bowl will Be playing here this afternoon in Inglewood, outside of LA. I may pop my head in to watch some of it, But my local team got beat two weeks ago, so I have no vested interest in the game.
Another sunny mid 70's day here. Will work on yard clean up today after breakfast. Seymour got up early, so He's already had a lil snacky snack. Will get him outside for some freash air & sunshine also...
Hope everyone's day is going lovely....Take care all!

Rather than a coral, isn't that a shark's tooth? Are you just posting pictures to make sure we're paying attention?

I have always wanted to become part of a comb jelly when I die, which is why my ashes will be scattered in the sea at a place where they exist. I really hope it will be one with flashing lights !
