You know the drill, I don't own the Fallout series.
AN: Just when you thought it was safe to go back in the water.
Other Aquatic Creatures
Mirelurks are far from being the only mutants that take to the water. Many of the following animals can be found near or in water, from harmless little frogs to Mantis Shrimp that tower over Super Mutants. Isn't learning fun?
Gulpers
Descended from Salamanders and Newts, these amphibious animals can be found in freshwater and salt water marshes and ponds. Easily mistaken for reptiles, they are in fact amphibians and are capable of breathing air and extracting oxygen from the water. They live in family groups of 5 and keep their nest in warm environments, usually around groves of trees where they like to hang upside down by their powerful prehensile tail. A little over 5ft in height, Gulpers hunt prey using their large webbed hands and serrated teeth. Gulpers also possess a mild healing factor, with their bodies regenerating damaged wounds in a matter of hours.
Anglers
Descended from the Angler Fish, how these mutants went from deep sea, twilight zone dwelling fishes to semi-aquatic humanoids is a mystery. Found in salt water lagoons and fresh water swamps, they are dangerous predators that should not be approached. Anglers often live in small families, usually made up of three adults and will consume any prey they can find.
Like their ancestors, they use ambush tactics to hunt. On their foreheads, there is a natural growth that resembles a Lure-Weed; by staying submerged in the water, they wait for prey such as Radstags or unsuspecting herbalists. Anglers are humanoid in appearance and their hands and feet are webbed. They also possess fins on their forearms, shins, and back and gills on their necks.
Anglers are incredibly fast and agile hunters, equipped with not only sharp claws, but also an acidic bile they can launch as fleeing prey.
Fog Crawlers
Believed to be a mutated form of Mantis Shrimp, or Squilla Mantis, Fog Crawlers are typically the apex predator of their area. Isolationists, they live solitary and nomadic lives, wandering around the swamps and mires they call home. Extremely aggressive, Fog Crawlers will attack anything that comes across them, using strong claws and forceful headbutts. Fog Crawlers will also jump into the air and land heavily back down to earth, stunning anything nearby. You'll hear a Fog Crawler before you see it as they make a low, but loud vocalizing sound.
Hermit Crabs
Woe to the unwary traveler who takes potshots at a blasted-out van only to anger the Hermit Crab living inside. Once a pet sold at boardwalk tourist traps to children for 8 dollars, the Hermit Crab is now a massive tank of a crustacean. Unlike their cousin, the Common Mirelurk, Hermit Crabs are born without natural shells and have to scavenge for makeshift armor, like a raider. In the Back-When times, the Hermit Crab would use abandoned sea shells from snails and nautiluses. These days, though, due to radiation; the Hermit Crab now makes its home in ruined vans and trailers.
Living a solitary and nomadic life, Hermit crabs carry their homes on their backs, moving from place to place to find prey. An ambush predator, the Hermit Crab tucks its body into its 'shell' and waits for an unsuspecting Radstag or scavenger before unrolling itself to attack. Armed with powerful claws, the Hermit crab is as strong as it is large. Thankfully slow moving, a Hermit crab is easily dodgeable, provided you recover from the shock of seeing a massive crab burst out of a food truck quick enough.
Frogs and Toads
Amphibious creatures found in ponds and creeks, these semi-aquatic mutants are (possibly) kin to the Mirelurk Kings. Frogs are some of the smallest of the amphibious mutants, even smaller than a Mirelurk hatchling. Timid things, the Frog has blue and green mucus-coated skin that has a bioluminescent glow. They use their elongated legs and prehensile tongues to catch insects such as fireflies.
Toads are far larger and far more aggressive than the more passive Frogs. Fat and misshapen, Toads live in groups of up to five. In the centuries following the Great War, they've grown sharp teeth and attack potential prey by leaping at them and attempt to strike at them with a bludgeon-like tongue. They carry their eggs on their backs in tumor-like growths and are even able to launch their parasitic eggs at potential prey, not unlike the Bloatflies their so found of eating.
Both Frogs and Toads are hatched from eggs and the hatchlings are refereed to as tadpoles, purely aquatic little animals that overtime will grow to be able to inhabit land and water.
Dolphins
A common sight on fishing boats and in Mirelurk nests, the Dolphin was once one of nature's most majestic animals. Now, like most things touched by radiation, it's pretty terrible to look at. Little is known about the modem Dolphin as a lack of scuba equipment and heavy radiation make underwater exploration incredibly difficult. Before the war, Dolphins were one of the most intelligent animals on Earth, now they decorate coastlines and boardwalks and make feasts for Rad-gulls.
Ghoul Whale
More legend than fact; stories of massive ghoulified sea monsters are common among fishermen and caravanners. Whales were the not only the largest mammals in the world, but once held the title of largest creatures on Earth ever. It's is possible that some survived in the depths of the ocean, where radiation may not have hit them immediately. Whether all whales have become ghoulified or just the ones who had the misfortune to be topside when the bombs hit is unknown.
