notes on sponges

Storyline for Video on Sponges
-Sponges by Tifani Panek
-What is a sponge?
-When I say sponge, you may be thinking of...
-Spongebob Squarepants
-Or maybe even a synthetic cleaning sponge.
But those are not the sponges I am talking about.
-Sponges are simple, multicellular but beautiful filter-feeding animals. They are from the phylum porifera and are invertebrates that live in the bottom of the ocean and cannot move from their surface.
-Sponges are also ancient creatures. 3.5 billion years ago, when the earth was a cold, empty and dark place, the first form of life appeared in the ocean- single-celled bacteria. And from single-celled bacteria came something very important. Stromatolites. These mounds here may look like just rocks but they are actually stromatolites. Stromatolites are mounds of living bacteria. Stromatolites were the first to use photosynthesis to turn carbon dioxide and water into glucose. This transformation released a byproduct- oxygen. The stromatolites slowly filled the ocean with oxygen. Then 650 million years ago, the deep freeze of the earth occurs and for 15 million years, the earth is a frozen snowball. But after the 15 million years, the ice begins to melt and the earth wakes up with much higher oxygen levels and is a new place. However, the primitive bacteria deep in the ocean clung on throughout the big freeze and earth enters the dynamic period in history called, “the Cambrian explosion” where increased oxygen levels lets the first kind of creatures to form in the ocean- sponges were one of them. Sponges, being one of the first living organisms on earth, are actually one of our oldest ancestors. And sponges, being the tough creatures that they are, are still found around today.
-Sponges come in all shapes, colors, and sizes. There are vase sponges, bushy sponges, branching sponges, encrusting sponges and many more
- There are actually many different types and shapes of sponges. Each one is uniquely different
