In the Southern Ocean, one species, the Antarctic krill, Euphausia superba, makes up an estimated biomass of around 379,000,000 tonnes, making it among the species with the largest total biomass. Annual precipitation at sea level on Heard Island is in the order of 1,300 to 1,900 mm, meteorological records at Heard Island are incomplete. The status of the penguins is also unclear. The exact definition of taxonomy varies from source to source, but the core of the remains, the conception, naming.
