Selkidomus is a type of beast demon that lives in the seas around the Boiling Isles. According to Eda, they are generally peaceful creatures, but may attack if provoked or if the safety of their young is threatened. They are capable of producing a viscous golden substance known as Selkigris, which is known for its high monetary value.
Appearance[]
The Selkidomus is a giant seal-like sea monster. Its flippers and its stance when it's on land resemble those of pinnipeds or seals. Like seals, the Selkidomus has four flippers; except that its front flippers are bigger and have three digits on each one, while the hind flippers are smaller and have only two digits. Unlike seals, the Selkidomus has a long tail that ends in a whale-like fluke, with a small spine on the tips of it. The color of its "skin" is grayish purple with a light-gray underbelly, while its nose and forehead are a darker shade of purple. Despite the appearance of gray, seal like skin, the selkidomus has some amount of scales covering its body. It has black eyes and pink coloration that surrounds the eyes. It has three webbed shark-like dorsal fins on its body: a small one on its neck, a big one on its back, and another small one on its tail. The Selkidomus also has aquatic plants growing, looping, and covering its neck, back, and sides of its mouth.
Juvenile selkidomus resemble their adult counterparts, albeit smaller and with rounder proportions. They have a single dorsal fin, a sapling on their head, and two leaf bristles protruding from their muzzle.[1]
Personality[]
According to Eda, the Selkidomus is a peaceful creature, and it will only attack if provoked. However, if the Selkidomus is a mother, it will attack anything or anyone that she perceives as a threat to her infant. But if one is able to prove to the mother that they are not a threat to her baby, or lucky enough to be recognized as not a threat at all, the mother Selkidomus will calm down. Additionally, a mother Selkidomus has a sense of gratitude to those who helped her defend herself and her infant. And in return for helping her, a Selkidomus mother will reward anyone with its precious Selkigris.
Background[]
The Selkidomus is first seen on a "wanted" poster on Greg's List, with a reward of 1,000,000 snails on it, when Luz suggests that a way to boost her, Eda, Lilith, and King's confidence is by taking on the biggest bounty they can find. However, Eda refuses because they need to lie low while her powers are still weak, and what they need is a much easier bounty. After Luz overhears Eda saying that she is spending the money only on food that she can eat, she feels guilty and decides to make it up to Eda. Luz, along with King, joins a crew to hunt for the Selkidomus.
Later, at the Simmering Shoals, where the Selkidomus was last sighted, the Selkidomus appears and begins attacking the crew by launching spikes at them. Luz, using her ice magic by redirecting it, places it in a position, so it can easily be captured, and using her plant magic to restrain it, successfully captures the Selkidomus. However, it breaks free and escapes when a mysterious pirate bombards their ship and steals the reward money.
After Luz and the pirate, revealed to be Eda, confront the Golden Guard on an island, Eda demands to know why Emperor Belos wants the Selkidomus dead. The Golden Guard replies that he is simply following orders, and soon gives Luz and Eda a compromise: Kill the Selkidomus, or King will be drowned in the Boiling Sea. With no alternative solutions left, Luz agrees, much to Eda's chagrin; the latter follows her, and she reveals that she is doing this to make up for everything that happened to Eda.
Luz engages the Selkidomus and fights it, but the beast soon overwhelms her. While she tries killing it, Eda stops her, reassuring her that she brought joy into her life. They then discover that the Selkidomus has a child, and together, they come up with a plan to save themselves without hurting it. Using plant and light magic, Luz and Eda fool the Golden Guard into thinking that they killed the Selkidomus, prompting him to release King and fly off. Upon his departure, Eda warns the Selkidomus that it needs to leave the area, as it isn't safe. As a reward for protecting it and its child, the Selkidomus vomits up golden selkigris, which, according to Eda, is worth a fortune.[2]
The picture of a Selkidomus appears on Hooty's demonology board among other beast type demons.[3] Four years after Belos' defeat and the Coven System dissolved, the Selkidomus and its child are seen swimming together peacefully.
Powers and abilities[]
- Spine shooting: When threatened, the Selkidomus can inflate its neck into a balloon, reveal many spines, and then eject the spines in every direction, hitting any potential target.
- Selkigris production: The Selkidomus can barf up a substance known as selkigris, which is noted to be very valuable.

Behind the scenes[]
Early development[]
According to concept art for the Selkidomus, the creature initially had a more serpentine appearance, with yellow skin, spines, and a webbed tail, as well as a secondary, seal-like hide.[4]
Name and basis[]
The Selkidomus may be based on the Selkie, a Celtic-Norse mythological creature that shapeshifts between human and seal forms by donning and shedding their enchanted sealskin. This is supported by the creature having the skin of a pinniped draped around its body in its original design.[4] "Selkie" is the Scottish term for "seal", thus combined with the suffix "-domus", meaning "house" or "ruling" in Latin, "selkidomus" roughly means "ruler of seals", befitting the creature. Their ability to produce selkigris also alludes to a sperm whale's ability to produce ambergris.

Trivia[]
- In "Eclipse Lake", in the Emperor's Castle, a book that Belos left open reveals that the scales of a Selkidomus are one of the items needed in the construction of a grimwalker.
- It seems to be a carnivore. When vomiting Selkigris for Luz and Eda, a skull is found inside.
