The '''[[colossal squid]]''', sometimes called the [[Antarctic]] squid, is believed to be the largest squid species in terms of mass. It is known from only a few specimens, and current estimates put its maximum size at 12–14 m (39–46 ft) long and weighing possibly up to 750 kg (1,650 lb), based on analysis of smaller and immature specimens, making it the largest known invertebrate.
'''[[Antarctic krill]]''' is a species of [[krill]] found in the [[Antarctica|Antarctic]] waters of the [[Southern Ocean]]. It is a small, swimming crustacean that lives in large schools, called swarms, sometimes reaching densities of 10,000–30,000 individual animals per cubic meter. It feeds directly on minute phytoplankton, thereby using the primary production energy that the phytoplankton originally derived from the sun in order to sustain their open ocean life cycle.


The largest recorded specimen was captured in 2007 by a New Zealand fishing boat off [[Antarctica]]. It was initially estimated to measure 4.5 m (15 ft) in length and weigh 450 kg (990 lb). The squid was taken back to New Zealand for scientific study. A study on the specimen later showed its actual weight was 495 kg (1,091 lb), but it only measured 4.2 m (14 ft) in total length as a result of the tentacles' shrinking post mortem.
It grows to a length of 6 cm, weighs up to 2 grams, and can live for up to six years. It is a key species in the Antarctic ecosystem and is, in terms of biomass, probably the most abundant animal species on the planet.

Antarctic krill is a species of krill found in the Antarctic waters of the Southern Ocean. It is a small, swimming crustacean that lives in large schools, called swarms, sometimes reaching densities of 10,000–30,000 individual animals per cubic meter. It feeds directly on minute phytoplankton, thereby using the primary production energy that the phytoplankton originally derived from the sun in order to sustain their open ocean life cycle.

It grows to a length of 6 cm, weighs up to 2 grams, and can live for up to six years. It is a key species in the Antarctic ecosystem and is, in terms of biomass, probably the most abundant animal species on the planet. In 2019, the Antarctic krill was featured on a stamp of Westarctica to celebrate its role as a vital part of the Antarctic ecosystem.
