Eel

Eels are available in only the darkest worlds. They become available for purchase after researching Seabed Geology provided you have at least 50 fish. Their description is "Offer a new home and fish supply to an eel. They can round up fish and sand."

Career Path
Eels jobs become available after researching Eel Habitats.The positions are Eel Technician and Eel Sifter. Sifter is one of 3 positions able to produce kelp. Technician is a research position.

Laboratory Research
There are 4 upgrades that can be researched that are specific to only eels and 1 generic upgrade that affects eel income. The research listed below is available in every world and has an effect on eels and their jobs: {| class="article-table" ! scope="col" |Upgrade ! scope="col" |Description ! scope="col" |Result ! scope="col" |Cost

Eel Habitats
So we keep seeing these things we thought were kelp on the seabed, but it turns out they're not kelp. What are they? Eels are twice as effective now we know how they prefer to live. Eels are also able to specialise in a variety of different ways with a place to store their things. Eel power x2

We can probably figure out a way to make eel pits cosier for their inhabitants. Eels are twice as effective, and so are eel pits. Expect many baby eels in the future. Eel power x2

There has to be a way to harness the powers of some of the eels. We all know they have powers. Painful ones. Eel technicians are twice as effective. So are our machines. Convenient! Eel technician power x2

Story
Warning: This section includes speculation, as canon answers don't yet exist. Snaking elegance, talented attendants.

The eels are technologically gifted, though they haven’t developed electronics of their own. This may be due to a lack of ambition, meek and unassuming as they are. The sharks are hesitant at first, perhaps because their curiosity led to some painful surprises, but soon come to trust their eel friends.

Once the eels learn of their ancient ancestors they become much more productive. This suggests that eels in general lack confidence. It may be that they’re so willing to help the sharks because of the kindness and encouragement they’re shown.

Trivia
Electric eels can generate up to 800 volts of electricity, more than 3 times the voltage of a standard European outlet and almost 8 times the voltage of American outlets. But electric eels aren't eels at all! Their snake-like bodies are similar to an eel's, but has a different arrangement of fins. Electric eels are freshwater fish, and while genuine eels can sometimes be found in fresh water they are primarily ocean animals.
