"The one becomes the many: The first multi-cellular organism emerges."

Sponges, "Porifera", "Parazo" are different names for this group of organism. It's the fifth generator in the tech tree of life within the primary simulation.

Design

The Sponge resembles three pink tube sponges, very likely demosponges. These sponges could possibly represent the stovepipe sponge, the giant barrel sponge, or possibly other pink species of sponges. They are the first generator in the Ocean habitat, and the only one that doesn't move. Bubbles come out of them and dozens of them are spread out across the rocks on the ocean floor. When clicked on, it makes a squishy noise.

Description

"The world's first multi-cellular organism, sponges are stationary filter feeders. They are a product of multiple eukaryotic cells coming together."

Upgrades

Sponge has 4 upgrades, increasing the generator efficiency with a total x12 multiplier.

Icon	Name	Description	Cost	Efficiency	Requires
	Coral	Coral is a marine invertebrate with a hard calcium-carbonate exoskeleton. Colonies of corals that grow together can create reefs, diverse underwater ecosystems that provide a home for many sea creatures.	Entropy 40,000	100%	6 Sponge
	Muscles	Muscles are fibrous tissue in an animal's body with the ability to contract. This action enables the muscles to move, in turn moving the bones that are attached to them.	Entropy 100,000	100%	Tissue
	Oscula	As sponges gain nutrients by letting water pass through them, they also need a way to excrete what’s left over. The oscula is a hole where this waste water passes out of the sponge when it’s done feeding.	Entropy 3.57e8	50%	50 Sponge Coral
	Hermaphroditism	Organisms with hermaphroditism have either a complete or partial set of both male and female reproductive systems. Animals with hermaphroditism include clown fish, earthworms, and snails.	Entropy 3.87e11	100%	100 Sponge Asexual Reproduction

Achievements

Icon	Name	Description	Requires
	Squishy	Sponges do not have nervous, digestive, or circulatory systems. Instead most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes.	25 Sponge
	Hospitable	Sponges can provide a home for up to 16,000 other creatures while they are alive.	50 Sponge
	Sponge Bath	There are about 5,000 species of sea sponges found worldwide.	100 Sponge
	Startling Sponge Stats	The smallest sea sponges are one inch long. The largest can grow to four feet tall.	150 Sponge
	I'm Running Out of Sponge Puns	Many sponges are toxic to eat. They have few natural predators because of this.	250 Sponge

Trivia

• In the game, Coral is an upgrade for sponges, however, in real life, they are classified as cnidarians rather than sponges, relatives of the Jellyfish.
