Fish are the fourth and penultimate generator in the ocean and the eighth obtained generator overall. Fish are also the first generators considered vertebrates. Fish are any vertebrates that have fins, usually gills, and aquatic (however, some such as mudskippers and lungfish appear to be semiaquatic). Tetrapods evolved from fish, and thus cladistically making tetrapods fish as well.

Description

"With fins to maneuver the ancient seas, fish evolved from the less agile invertebrates and rapidly diversified to take control of the oceans."

Design

The fish resembles a turquoise-colored carp-like teleost fish. It bounces around in an invisible sphere wall in the Ocean, and swings its fins side to side to create an swimming animation. In the Ancient garden, a man hunts for fish in the Stone Age section, which represents the Fishing Upgrade. Next to the man are two fish laid over a rock.

When clicked on, it makes a bubbling noise similar to the Eukaryotic Cell.

Sharks

The sharks are six bonus upgrades that are unlocked - one after the other - by the Mystery Prize (7th daily mutation) every week for six weeks. The sharks show up in the Ocean garden view, where they swim around the environment and eat fish, with blood trailing behind them as they do so. This "fish hunt" is only visual and does not affect Entropy production. Every single shark has a swimming animation. All of them are completely silent.

For more information regarding the sharks, such as habitat, view the main page.

Upgrades

Fish has 16 upgrades, increasing the generator efficiency with a total x1.88508e9 multiplier. 9 of these Upgrades are only unlocked after you unlock the Mystery Prize on the 7th day of logging in.

Icon	Name	Description	Cost	Efficiency	Requires
	Gills	Gills are respiratory organs that allow fish to extract oxygen from the water around them. This lets them breathe underwater.	Entropy 2.33e6	25%	Fish
	Lungfish	Lungfish are freshwater fish that first became abundant in the Triassic era. They breathe air and can survive on dry land by burrowing into the mud with their fins.	Entropy 5e6	25%	Gills
	Cold Blooded	Cold-blooded animals rely on external heat sources to control their body temperature. This allows them to have conservative metabolisms and save energy, but can also make them vulnerable to overheating or freezing.	Entropy 1.33e7	33%	Fish
	Cartilaginous Skeleton	Some aquatic animals, such as sharks and rays, have skeletons made of cartilage instead of bone. This means that they are more durable, flexible, and buoyant.	Entropy 2.67e7	100%	Fish 7 Days of Daily Mutation
	Fins	The proto-limb. Fins would eventually develop into hind legs that would help mammals, reptiles, birds, and amphibians travel on land.	Entropy 3.7e7	50%	Fish
	Jaw	The articulated bones that surround the mouth, jaws made respiration and nutrition more efficient. They enable chewing, hold the teeth, and protect the tongue and soft palate.	Entropy 9.2e7	50%	15 Fish
	Medulla Oblongata	A structure located in the lower part of the brainstem, the medulla controls the autonomic functions of the body, including heartbeat, breathing, and sleeping. It evolved in fish around 500 million years ago and forms a large portion of the reptile brain.	Entropy 1.5e8	100%	Nerve Cord
	Replaceable Teeth	Sharks have teeth that grow in many rows at a time, and are replaced whenever one breaks or falls out. Some sharks lose 30,000 teeth or more in their lifetimes.	Entropy 4.27e8	100%	Cartilaginous Skeleton
	Excretion Opening	Most creatures develop a specific hole through which waste is exclusively excreted. This is necessary to evolve complex digestive systems.	Entropy 5.95e10	75%	50 Fish
	Eye	Evolving from a humble pigment spot, the eyeball is a round, jelly-like organ. It processes light into electrical signals that travel from our retina to our brain. These signals are turned into images, enabling us to see.	Entropy 6.44e13	100%	Pigment Spot 100 Fish
	Shark	The earliest known sharks appeared over 420 million years ago. Both dangerous and endangered, these powerful predators and sleek swimmers are at the top of the underwater food chain.	Entropy -	-	7 Days of Daily Mutation Replaceable Teeth
	Leopard Shark	Leopard Sharks are so named because of their distinctive pattern of spots and stripes. They live in coastal regions and pose no threat to humans, who often hunt them for their meat.	Entropy -	300%	7th daily reward Replaceable Teeth
	Tiger Shark	The distinctive stripes of a Tiger Shark, the source of its name, are most prominent in juveniles and fade as the fish matures. They are solitary nocturnal hunters, and are known to eat almost anything, including human-made garbage.	Entropy -	900%	14th daily reward Replaceable Teeth
	Whale Shark	The Whale Shark is the largest known fish in the world, growing up to 18.8 meters long. It is a gentle giant, feeding mostly on plankton and small fish, and juveniles of the species have been known to swim peacefully with human divers.	Entropy -	500%	21st daily reward Replaceable Teeth
	Great White	The most famous species of shark, Great Whites are the largest predatory fish in the oceans and can grow to up to 6 meters long. They are known to sometimes attack humans, but prefer to eat dolphins, whales, and seals, and have a bite force of 4,095 lbf.	Entropy -	1,700%	28th daily reward Replaceable Teeth
	Hammerhead	Hammerhead sharks are known for their flat, horizontally-shaped heads. This distinctive trait gives them a wider range of view, allowing them to scope out the seas for their prey. They are a protected species.	Entropy -	3,200%	35th daily reward Replaceable Teeth
	Megalodon	Megalodon is an extinct species of shark that lived from 23—6.5 million years ago. While its exact size remains unknown, estimates place its length at up to 18 meters long, and it is widely regarded as one of the largest and most deadly predators in history.	Entropy -	10,000%	42nd daily reward Replaceable Teeth
