The great sturgeon (Huso huso) is a large species of sturgeon found only in Endless Ocean 2.

It is the largest species of sturgeon. In fact, it is one of the largest bony fish in the world.

In-Game[]

Marine Encyclopedia[]

Endless Ocean 2[]

Description[]

"This species is the largest of the sturgeon family, with one fish reported to be 26ft long and one ton in weight.

The report is old and the accuracy of the measurements is questionable, which makes it hard to say if this record is true or false."

Location[]

Endless Ocean 2[]

These can be found in Ciceros Strait around coordinates C-1, C-2, D-1, D-2 and D-3. They can also be found in the Cavern of the Gods around coordinates A-1, A-2, A-3, A-4 and B-4, but only after it has been reopened.

There is a legendary great sturgeon known as Lady Dorthea, found in North Canyon alongside the normal great sturgeons.

Behavior[]

In Ciceros Strait, these swim in circuits at a slow pace during the daytime. In the Cavern of the Gods, two or three of these swim up and down the western hallway.

Notes[]

  • This is one of GG's favorite creatures.
  • The great sturgeon was replaced in Endless Ocean Luminous by a different species: the green sturgeon.
    • Despite the removal of the great sturgeon, Endless Ocean Luminous reports that Lady Dorthea is of the species Huso huso, meaning that she is still considered a great sturgeon, not a green sturgeon.

Real-Life information[]

  • The in-game description of the largest recorded great sturgeon is partially correct - the largest record is said to be 26 feet (8 meters) long, and 3.5 tons (3.2 metric tons), or 7000 pounds (3200 kilograms)[1][2]. However, this record is disputed[3]. The officially confirmed maximum size is between 18 to 20 feet (5.6 to 6 meters)[4][5].
    • There is an old report of a specific sturgeon caught in the year 1827 that was 23 feet (7.2 meters) long and 3254 pounds (1476 kilograms)[6][7]. This is currently the largest verified and accepted record.
  • The great sturgeon is a critically endangered species[8]. The biggest threat to its numbers is human overfishing, as it is highly sought after for its caviar (eggs)[9][10]. There are caviar producers, however, who keep farmed sturgeon and can extract caviar without killing the fish, which slightly reduces pressure on wild populations[11][12][13]. However, illegal acquisition of sturgeon for their flesh & caviar is still a massive threat to their populations[14][15].
  • The distinct whiskers on the snout of the sturgeon, called barbels (BAR-bulls), are used to help them sense food[16]. They also have special organs called the ampullae of Lorenzini, which allow them to detect electrical currents given off by smaller fish[7][17]. These ampullae of Lorenzini are also present in sharks and rays[18]. The most common prey of the sturgeon is smaller fish[3].
  • An interesting adaptation of the great sturgeon is that it can tolerate water with much lower salinity than most ocean fish can, a trait known scientifically as being "euryhaline"[19][20]. It is also anadromous, meaning that it spends most of its life in the ocean but generally moves into freshwater, like rivers, to spawn[9][16].
    • A famous example of an anadromous fish is the Chinook salmon, which returns upstream in events known as "salmon runs"[21].
  • Great sturgeons are exceptionally long-lived, reaching over 100 years of age if not caught by humans before then[4][6].
  • Other common names for the great sturgeon include European sturgeon, giant sturgeon, hausen, and beluga (not to be confused with the small whale of the same name)[2][5][22].
