Hey, guys....single celled organisms aren't "animals"...they're protists.
The first animals were probably sponges.

No The first animals were sea creatures, small, and simple life forms which later evolved into mamal and reptiles, and fishes.
Sea urchins and most other animals begin their embryonic development as small clusters of cells, called blastulas.
The seas were full of creatures millions of years before the first dinosaurs appeared.

The timing of the first animals to leave the oceans is not precisely known: the oldest clear evidence is of arthropods on land around 450 million years ago.
BTW Isis, single cell organisms are not animals they are SINGLE CELL ORGANISMS!

No. There were many more animals before them.
Some scientists believe marine "sponges" were the first animals: http://news.nationalgeographic.com/news/2002/04/0401_0401_shapeoflife1.html
