Abstract Haliphron atlanticus Steenstrup, 1861 (= Alloposus mollis Verrill, 1880) is reported from New Zealand waters on the basis of a single specimen of giant proportions caught recently by fisheries trawl off the eastern Chatham Rise. This specimen, possibly the largest known of this species and of all octopods, proves to be the first validated record of Haliphron from the South Pacific. Although extensively damaged, details of its morphology and anatomy are described.

Evidence suggests that Haliphron is not monospecific, with at least two species, both represented in the Atlantic Ocean, and there is a greater divergence among these specimens and a giant octopus from North Atlantic.

Capture of the Coronate medusa Periphyllopsis braueri, by the Giant Seven-arm Octopus Haliphron atlanticus

The Seven-arm Octopus, Haliphron atlanticus, was observed holding a coronate medusa, Periphyllopsis braueri, by the remotely-operated vehicle (ROV) Dolphin-3K, and it appears that gelatinous prey species are important components of the diet of Haliphrons.

The first observations of the giant deep-sea octopus Haliphron atlanticus with prey are reported, using remotely operated vehicles, and stomach content analysis confirmed predation on cnidarians and gelatinous organisms.

The likely directions of faunal flows were inferred based on affinity indices, showing that Mauritania could be the most probable source of the octopod species of the Canary Islands and the rest of the Macaronesian archipelagos.

While maneuvering the jelly, H. atlanticus appears to use the jelly’s marginal nematocystic tentacles for protection, which constitutes further evidence that all four octopod families of the Argonautoidea display various interactions with gelatinous zooplankton.

A review on the biodiversity, distribution and trophic role of cephalopods in the Arctic and Antarctic marine ecosystems under a changing ocean

Cephalopod predators in the polar regions are likely to be more influenced by climate change than those from the rest of the World: Arctic fauna is more subjected to increasing temperatures per se, with these changes leading to increased species ranges and probably abundance.

Assessments of metallic contents in rare cephalopods from the Canary Islands: relationships with depth habitat and body size

Metal contents in large and elusive cephalopod species were dominated by Fe, Ni, Al, Zn, and Sr, with these species being able to carry important amounts of these elements to predators such as deep-diving odontocetes that reside around the Canary waters.
