The way the Ratchet & Clank wiki capitalizes words has changed; therefore, this article should be checked, and, if necessary, capitalization should be fixed.
Pool Sharks (also called Sharkigators or Sewer Sharks, depending on the location) were biting, amphibious beings that lived in several watery areas.
There were two different color variant of the sharks.
In the first game, the original dark green color variant was present both in the pools on Umbris and in the oceans on Rilgar. Later in Going Commando, the sharks in the factory on Notak had also the original green color.
In Going Commando, on Notak, the sharks swimming in the ocean had an orange color. Then, from Up Your Arsenal onwards they were always orange.
In Size Matters, the orange sharks that lived on Pokitaru had human-like green pupiled eyes, instead of their glowing yellow eyes in the other games. They also moved differently in Size Matters rather than just moving upwards, turning 180 degrees, and plunging downwards.
Also, in Size Matters, in the beginning part of Dreamtime, the shark's fins could be seen in the water as well as a much larger moving unknown navy blue/purple polygon shape, presumably a larger variant of the shark.
As an environmental threat
Non-attackable sharks were found throughout both the Solana Galaxy and the Bogon Galaxy and were the creatures that ate anyone who decided to swim too far from land. They could be found lurking in the water on any level that did not require the player to swim, making the sharks act as a deterrent for players straying too far from anywhere else in the level besides the set path. On most levels, players could assess whether or not the water was safe; If the water was transparent, Ratchet could swim without being harmed. If he fell in murky water, he would get eaten almost instantly and would be reset to the last Checkpoint. As a prewarning, fins could be seen in the water; however, Planets Daxx and Florana in Ratchet & Clank: Up Your Arsenal lacked them. After falling in the water, Players were given around five seconds before one of the creatures attacked.
In Size Matters, the sharks also appeared in the Multiplayer map called Island Escape. If a player jumped into the water, they would get eaten by a shark, followed by a message "No swimming allowed."
As an enemy
Pool Sharks were encountered as fightable enemies on the outskirts of the end of the level on Umbris that ate Ratchet only if he was in water. These were the only living enemies in the level besides the Blargian Snagglebeast. A few swings of the wrench, or one Hyper-strike, could defeat them with ease. This was the only time that the Pool Sharks could be attacked.

In Secret Agent Clank the pool sharks could be seen swimming behind the glass walls of the Prison Showers

This "Trivia" section, or part of it, needs improving and should ideally be integrated into a "Behind the scenes" section and/or the main article, with the trivia section eventually reduced or, ideally, removed entirely.

- The Sewer Shark bared many similarities with the Lurker Shark from the Jak and Daxter universe, as both enemies were used as a way to keep the player from hitting the levels borders by providing a natural deterrent organic to the environment.
- In Up Your Arsenal, the shark didn't open its mouth when it ate Ratchet.
- In the Ratchet & Clank Demo, the Pool sharks also didn't open their mouths either, in fact they used exactly the same animation, but in the official release, they did. This means that the "Chomping" animation was eventually scrapped in later games in favour of a simple "Swallow whole" animation.
- If Ratchet was eaten by a pool shark in Ratchet & Clank: Going Commando, while "in" the shark, and at the same time was attacked by a different enemy, the game would freeze.
Behind the scenes
When the sharks attacked, all of the games kept the same "gulping" sound when they ate Ratchet and Clank. This gulping sound was also used in the Pokitaru Infobot from the original Ratchet & Clank.
In the re-imagined series, the sharks were instead known as "Killer Fish."
