That's Megalodontia... Its hunger knows no bounds. I'd say more, but I'll just shut my trap and let you focus on staying OUT of that thing's trap!

Megalodontia is a type of King Salmonid that appears in Salmon Run Next Wave during an Xtrawave. They are the third type of King Salmonid to debut in Splatoon 3, making its first appearance during the Big Run on 2 December 2023.


A Megalodontia is the biggest King Salmonid in Splatoon 3, described to be "large enough to swallow a ship whole"[1]; the Squid Research Lab further elaborates by humorously specifying its bite radius as "1.4 boats wide".[2]

Megalodontia shares close similarities to Maws, but is much bigger in size. It has white bulging eyes, similar to other King Salmonids, and blue hair. Around its jaw is a giant contraption resembling orthodontic braces. On its back are various nets, as well as a large red bump with two bandages forming a cross.


Megalodontia will submerge and target a player. During that time, a large circle and crosshair will follow the player, indicating where it will emerge. After a certain amount of time, the circle stops moving and Megalodontia will jump out at the end of the bright rings and alarm effects, swallowing anything that was in the circle, similar to a Maws. This attack is uniquely capable of splatting other Salmonids, including Boss Salmonids, who will drop Golden Eggs upon death.

The large bump on Megalodontia's back is its weak point. Attacks to this bump will deal 70% more damage to it. For example, a direct hit with a Golden Egg cannon will deal 1,360 damage instead of 800.

A Megalodontia's health, like other King Salmonids, is linearly correlated to the room's hazard level, using the formula 0.7 * MaxHP + 0.005 * HL(%) * MaxHP, where HL denotes the hazard level percentage (capped at 60) and MaxHP is set at 65,000 for Megalodontia. For example, a team of Apprentice 40/99 (hazard level 8%) will meet a Megalodontia with 48,100 HP. When facing a team of Overachievers 0/99 (hazard level 60%) or above, Megalodontia has the maximum 65,000 HP.[3]


  • The weak point on Megalodontia's back always faces where it previously attacked. With Megalodontia's first attack, its back will be facing where the first boss salmonids spawn. Players can use this knowledge to position themselves near the weak point before the next attack happens.
    • Players targeted by the attack should note where the previous attack occurred and try to get the next attack to happen in a place where the weak point is exposed to the team or near Golden Eggs.
  • Megalodontia's attack has the ability to take out other Boss Salmonids when it emerges. Targeted players can use this to their advantage by causing it to attack in an area with a large amount of Boss Salmonids to gain Golden Eggs.
    • When doing this, players should be mindful not to lure the Megalodontia into a location where its weak point is difficult to hit, or a location where a player may end up trapped.
    • Any golden eggs caught in the attack radius will be shoved aside.
  • If aimed correctly, chargers can hit Megalodontia's body and weak point simultaneously, dealing 270% damage per shot.[4]
  • During a Triumvirate wave, a Megalodontia's biting attack will deal significant damage to the Cohozuna and Horrorboros. As the other King Salmonids are more fragile than it, players may want to let the Megalodontia survive long enough to take out one or both of the other two.


Eyewitnesses report a new King Salmonid named Megalodontia. It's claimed to be the biggest so far – large enough to swallow a ship whole, should the mood take it. Grizzco speculate it may come ashore in early December… #Splatoon3

Speaking of ocular enhancement, keep your eyes peeled this December for Megalodontia, a new King Salmonid! It's the largest observed—we estimate its bite radius at 1.4 boats wide. Yes, we're using boats as a unit of measurement! Desperate times call for desperate measurements!

  • Although intended to debut during the Barnacle & Dime Big Run, due to a bug it was possible to combat Megalodontia early by replaying certain job scenarios on version 6.0.0 that had been made in version 5.1.0 during a rotation with a random King Salmonid. Said scenario must contain an Xtrawave but with the uploader having failed to clear Wave 3 for this to possibly occur.[5]
    • This is because the game picks a King Salmonid for a random Xtrawave (and records this data) only after Wave 3 is cleared. Failure to clear Wave 3 forces the game to determine a King at the time of upload but erroneously from the updated pool with Megalondontia as a potential candidate.
  • Megalodontia has the highest possible HP out of all Salmonids, at 65,000 HP.
  • Similar to Maws, a player can escape from Megalodontia's bite attack if they are at the edge of its radius and moving with enough momentum.
    • This can also be accomplished by using the Kraken Royale's invincibility.
  • While other King Salmonids are treated as generic terms (e.g. "a Cohozuna"), Megalodontia is treated as a proper noun, wrongfully implying there is only one known member of its kind.
  • Megalodontia is the only King Salmonid and one of the two Salmonid kinds as a whole along with the Slammin' Lid that can deliberately damage other Salmonids.


Megalodontia, more commonly known as macrodontia is the condition of having one or several teeth too large for the jaw; the word is a portmanteau of the Greek words μεγάλο (megalo, "large") and δόντι (dónti, "tooth"). Likely intended to reference the word megalodon, an extinct species of giant shark, which has the same root words as megalodontia.
