The colossal squid (Mesonychoteuthis hamiltoni) is the world's largest invertebrate and its large size and some unique morphological characters have fuelled speculation that it is an aggressive top predator in the circum-Antarctic Southern Ocean. Here, we present estimates on the metabolic and energetic demands of this cold-water deep-sea giant. The estimated mass-specific routine metabolic rate for the colossal squid at 1.5°C was 0.036 µmol O2 h−1 g−1 and the projected daily energy consumption… 
Biology and ecology of the world’s largest invertebrate, the colossal squid (Mesonychoteuthis hamiltoni): a short review
The colossal squid Mesonychoteuthis hamiltoni (Robson 1925) is the largest (heaviest) living invertebrate and although it is preyed upon by many top predators, its basic biology and ecology remain
The evolution of gigantism on temperate seashores
Minimal disruption, together with the early evolution of metabolically-active consumers and the positive feedbacks they engendered, accounts for the evolution of molluscan gigantism in the North Pacific.
Alien vs. Predator: interactions between the colossal squid (Mesonychoteuthis hamiltoni) and the Antarctic toothfish (Dissostichus mawsoni)
Data collected onboard two South Korean longliners in 2011–2014 targeting Antarctic toothfish provided insights into trophic interactions between two Antarctic top predators: the colossal squid
Gigantism and Its Implications for the History of Life
Gigantism as a hallmark of competitive superiority appears to have lost its luster on land after the Mesozoic in favor of alternative means of achieving dominance, especially including social organization and coordinated food-gathering.
Cephalopods as Predators: A Short Journey among Behavioral Flexibilities, Adaptions, and Feeding Habits
The diversity of cephalopod species and the differences in morphology and the habitats in which they live, illustrates the ability of this class of molluscs to adapt to all marine environments,
Mitochondrial genome diversity and population structure of the giant squid Architeuthis: genetics sheds new light on one of the most enigmatic marine species
The results show no detectable phylogenetic structure at the mitochondrial level and that the level of nucleotide diversity is exceptionally low, consistent with the hypotheses that there is only one global species of giant squid, Architeuthis dux, and that it is highly vagile.
A draft genome sequence of the elusive giant squid, Architeuthis dux
This annotated draft genome of A. dux provides a critical resource to investigate the unique traits of this species, including its gigantism and key adaptations to deep-sea environments.
Trophic and reproductive biochemistry of a deep-sea gelatinous octopus, Opisthoteuthis calypso
Analysis of biochemical composition of the cirrate octopod, Opisthoteuthis calypso, collected off the coast of Portugal suggests that the gelatinous musculature of the Cirrate octopus may not be a direct consequence of food limitation, but rather associated with reduced selective pressure for strong swimming ability in the deep sea.
The giants of the phylum Brachiopoda: a matter of diet?
The species of the brachiopod Gigantoproductus are giants within the Palaeozoic sedentary benthos. This presents a dilemma as living brachiopods have low‐energy lifestyles. Although brachiopod

Growth and distribution of young Mesonychoteuthis hamiltoni Robson (Mollusca: cephalopoda): an antarctic squid
Thirty seven juvenile specimens and one adult specimen of the cranchiid squid Mesonychoteuthis hamiltoni were captured by the opening and closing RMT8 net during RRS ‘Discovery’ cruise 100 (1979) in
Feeding Habits and Prey Consumption of Antarctic Minke Whale (Balaenoptera bonaerensis) in the Southern Ocean
The Antarctic minke whale (Balaenoptera bonaerensis) is the most abundant baleen whale species in the Southern Ocean and data on prey consumption is useful to understand their feeding ecology and role in the ecosystem.
Decline in Pelagic Cephalopod Metabolism With Habitat Depth Reflects Differences in Locomotory Efficiency.
Since strong locomotory abilities are not a priority in the deep sea, deeper-living cephalopods may rely more heavily on means of locomotion that are more efficient than jet propulsion via mantle contractions--means such as fin swimming or medusoid swimming utilizing the arms and extensive webbing present in many deep-living species.
Behavior of midwater fishes under the Antarctic ice: observations by a predator
Using video sequences with synchronized positional data recorded by Weddell seals to describe the vertical distribution, diel movements, trends in abundance, and swimming behavior of two ecologically important fish species in McMurdo Sound, Antarctica provided clarification and new insights into the behavior, interactions, and ecology of species that have been especially difficult to study.
How long would it take to become a giant squid?
Laboratory and field studies suggest that cephalopod growth occurs rapidly and is linked to temperature throughout a short life span. For giant squid such as Architeuthis, a paucity of size-at-age
Light-limitation on predator-prey interactions: consequences for metabolism and locomotion of deep-sea cephalopods.
It is suggested that, where high-speed locomotion is not required, more efficient means of locomotion, such as fin swimming or medusoid arm propulsion, are more prevalent.
Consumption of Antarctic krill by Minke whales
The consumption of Antarctic krill by an “average-sized” (male 6994 kg; female 8249 kg), sexually mature Minke whale was estimated, from stomach capacity, ingestion rate and respiratory allometry methods.
