A Review of Southern Ocean Squids Using Nets and Beaks
Marine Biodiversity (2020) 50:98 https://doi.org/10.1007/s12526-020-01113-4 REVIEW A review of Southern Ocean squids using nets and beaks Yves Cherel1 Received: 31 May 2020 /Revised: 31 August 2020 /Accepted: 3 September 2020 # Senckenberg Gesellschaft für Naturforschung 2020 Abstract This review presents an innovative approach to investigate the teuthofauna from the Southern Ocean by combining two com- plementary data sets, the literature on cephalopod taxonomy and biogeography, together with predator dietary investigations. Sixty squids were recorded south of the Subtropical Front, including one circumpolar Antarctic (Psychroteuthis glacialis Thiele, 1920), 13 circumpolar Southern Ocean, 20 circumpolar subantarctic, eight regional subantarctic, and 12 occasional subantarctic species. A critical evaluation removed five species from the list, and one species has an unknown taxonomic status. The 42 Southern Ocean squids belong to three large taxonomic units, bathyteuthoids (n = 1 species), myopsids (n =1),andoegopsids (n = 40). A high level of endemism (21 species, 50%, all oegopsids) characterizes the Southern Ocean teuthofauna. Seventeen families of oegopsids are represented, with three dominating families, onychoteuthids (seven species, five endemics), ommastrephids (six species, three endemics), and cranchiids (five species, three endemics). Recent improvements in beak identification and taxonomy allowed making new correspondence between beak and species names, such as Galiteuthis suhmi (Hoyle 1886), Liguriella podophtalma Issel, 1908, and the recently described Taonius notalia Evans, in prep. Gonatus phoebetriae beaks were synonymized with those of Gonatopsis octopedatus Sasaki, 1920, thus increasing significantly the number of records and detailing the circumpolar distribution of this rarely caught Southern Ocean squid. The review extends considerably the number of species, including endemics, recorded from the Southern Ocean, but it also highlights that the corresponding species to two well-described beaks (Moroteuthopsis sp. -
<I>Teuthowenia</I> (Oegopsida)
BULLETIN OF MARINE SCIENCE, 36(1): 1-85, 1985 SYSTEMATICS, BIOLOGY AND BIOGEOGRAPHY OF THE CRANCHIID CEPHALOPOD GENUS TEUTHOWENIA (OEGOPSIDA) Nancy A. Voss ABSTRACT Teuthowenia is comprised of three discrete, closely related, allopatric species. Synonymies, definitions, diagnoses and keys to all developmental stages are presented, along with a review of the complex history of the genus and detailed illustrations. The discrete, ecologically distinct, distributional patterns of the three species reflect the influence ofa number of biological and physical factors. T. megalops (Prosch) is confined to the highly productive Atlantic subarctic and the highly productive areas of the North Atlantic temperate region. T. maculata (Leach) is restricted to the area of year-round, high productivity in the eastern tropical Atlantic. T. pellucida (Chun) is distributed circumglobally in the mixed and fringing waters of the Southern Subtropical Convergence. The species display similar patterns of ontogenetic descent from near-surface waters to midwater depths of about 1,000 m to in excess of 2,500 m where the animals mature, mate and spawn. Teuthowenia species have differentiated physiologically and developmentally as well as morphologically. Variations in the maturity-related morphological features among the species suggest differences in behavioral patterns for courtship and copulation. The genus displays a high rate of evolution in male and female secondary sexual characters. The relationships of Teuthowenia with Egea and Megalocranchia, which together comprise the monophyletic Megalocranchia group, and with the other taoniin genera are discussed. The taxonomic confusion surrounding the cranchiids was resolved in part by the familial revision of N. Voss (1980). The phylogenetic history of the family was reconstructed by N. -

Signed; _________________________________ Christine H. Jackson iv ABSTRACT Determining the biotic and abiotic influences on the distribution and abundance of marine mammals is essential for understanding the dynamics of the food chain. The predator-prey relationship can be deterministic in shaping both the community structure and function of marine ecosystems. This is especially pertinent to recovering toothed whale populations given their large size and high prey consumption rates. A greater knowledge of the trophic linkages between toothed whales and their prey will facilitate assessments of their combined impact on the ecosystem since marine food webs are a fusion of bottom-up and top-down energy and nutrient flow. -

Cephalopoda: Cranchiidae) from New Zealand Waters Aaron B
Journal of Natural History, 2015 Vol. 49, Nos. 21–24, 1327–1349, http://dx.doi.org/10.1080/00222933.2013.840747 Ontogeny of the deep-sea cranchiid squid Teuthowenia pellucida (Cephalopoda: Cranchiidae) from New Zealand waters Aaron B. Evans* and Kathrin S.R. Bolstad Earth & Oceanic Sciences Research Institute, Auckland University of Technology, Auckland, New Zealand (Received 14 December 2012; accepted 19 July 2013; first published online 18 February 2014) Teuthowenia pellucida is a cosmopolitan southern sub-tropical species, and is abundantly represented in local New Zealand collections. However, because of the morphological similarities between this and other cranchiid genera at early ontogenetic stages, accurate identification of small specimens can be difficult. Herein, the morphological changes characterizing six pre-adult developmental stages (termed A–F) are reported in detail, as well as adult morphology; new information is provided on fecundity. These findings comprise a small contribution toward eventual resolution of the systematically unstable Cranchiidae. Keywords: Cranchiidae; ontogeny; New Zealand; squid Introduction Teuthowenia is a squid genus of the family Cranchiidae, whose largely transparent tissues have resulted in the common name “glass” squids; their crypsis is also aided by eye photophores (Herring et al. 2002), which counter-shade down-welling light from the surface (Young and Roper 1976; Voss 1985). Cranchiids have been reported from all oceans except the Arctic (Norman and Lu 2000), and are found primarily between the mesopelagic and bathypelagic zones; however, some species, including those of the genus Teuthowenia, migrate vertically within the water column depending on maturity and seasonality (Voss 1985; Moreno et al. 2009). Teuthowenia contains three species (Voss 1980, 1985): Teuthowenia maculata and Teuthowenia megalops are found in the central and northern Atlantic, and Teuthowenia pellucida lives circum-globally in the southern sub-tropical belt (Voss 1985). -

Title/Name of the area: Madeira – Tore Presented by Maria Ana Dionísio (PhD in marine sciences), with a grant funded by Instituto da Conservação da Natureza e das Florestas and ISPA - Instituto Universitário de Ciências Psicológicas, Sociais e da Vida, [email protected] Pedro Ivo Arriegas, Instituto da Conservação da Natureza e das Florestas, [email protected] Abstract (in less than 150 words) Madeira-Tore EBSA includes a total of 17 seamounts. Seamounts are hotspots of marine life and in general they represent areas of an enhanced productivity, especially when compared with nearby abyssal areas. This EBSA has a total area of 197431 km2 with depths ranging from 25m (top of Gettysburg seamount) to 4930m (bottom of Tore seamount). The area includes a proposed Site of Community Importance - Gorringe Bank and an OSPAR High Seas Marine Protected Area – Josephine seamount. All structures included in the Madeira-Tore EBSA fulfill four or more out of the seven EBSA scientific criteria. A total of 965 species are present in this EBSA of which 7% are protected under international or regional law. Introduction (To include: feature type(s) presented, geographic description, depth range, oceanography, general information data reported, availability of models) The Madeira-Tore EBSA includes a total of 17 seamounts (Ampere, Ashton, Coral Patch (northern part of), Dragon, Erik, Gago Coutinho, Godzilla, Gorringe Bank (Ormond and Gettysburg seamounts), Hirondelle II, Josephine, Lion, Pico Pia, Tore, Seine, Sponge Bob, and Unicorn). These seamounts present particular features which make this area eligible as an EBSA when assessed against the EBSA scientific criteria. Benthic biological communities on seamounts are highly vulnerable to human activities. -
