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. -

INTRODUCTION Available catch statistics from 1965 through 1971 indicate • that world-wide landings of squid totalled roughly 700,000 metric tons annually. An additional 100,000 metric tons of cuttlefish and about 160,000 metric tons of octopus were also landed annually. Apart from the well-established squid fishery in the Monterey area of California and the relatively minor inshore squid fishery off Newfoundland, the North American fishing industry has tended to ignore the possibility of further exploitation and utilization of this resource. -
Finding of Uncommon Cephalopods

AnCÎslrolelilhis lichtensteinii, Histiotellthis bonne/Iii, H. rCl'ersa and the first record of Chirotellthis Feranyi in the Ionian Sea are reported here. Data were collected during a trawl survey carried out on red shrimp grounds during August 1993. Résumé : Dans ce travail, les auteurs analysent des espèces de Céphalopodes peu communes ou rares en Méditerranée, Ancislrotellthis Iichlensteinii, Histiotellthis bonnellii, H. reversa et ils signalent pour la première t"ois la présence de Chirotellthis l'eranyi en mer Ionienne. Les exemplaires ont été capturés au cours d'une campagne de chalutage expérimentale, sur des fonds ù crevettes rouges, au mois d'Août 1993. INTRODUCTION The SCal"CÎty of ecological knowledge on many species of cephalopods is certainly due to the technical problems of field observation and sampling. Information on distribution and abundance come mainly from CUITent research of biologi cal oceanography, fishing activities, analysis on stomach contents of mmine mammals and pelagic fishes. Recently, observations from submersibles have provided very interesting data about several aspects of the biology and ecology of cephalopods (Vecchione & Roper, 1991). Cephalopods are captured commercialy and for research purposes using a valiety of gears, primarily jigging machines, trawls and drift nets (Roper, 1991). While jigging, pela gic seining and potting are less destructive techniques that target specific sizes and species, trawling and drift netting are non-selective methods as far as size and specieS' are concer ned. -

Mullin National Marine Fisheries Service Southeast Fisheries Science Center PO. Drawer 1207 Pascagoula, MS 39568-1207 Submitted by: Dr. Nelio B. Barros Mote Marine Laboratory Center for Marine Mammal and Sea Turtle Research 1600 Ken Thompson Parkway Sarasota, FL 34236-1096 (941) 388-4441 x 443 (941) 388-4317 FAX May 2003 Mote Marine Laboratory Technical Report Number 895 ABSTRACT Sperm whales are common inhabitants of the deep waters of the Gulf of Mexico. To date, no information is available on the diet of sperm whales in the Gulf. This study sheds light into the feeding habits ofthese whales by examining data collected from free-ranging and stranded animals. Prey species included a minimum of 13 species within 10 families of cephalopods, the only prey type observed. The most important prey was Histioteuthis, a midwater squid important in the diet of sperm whales worldwide. Most species of cephalopods consumed by Gulf sperm whales are meso to bathypelagic in distribution, being found in surface to waters 2,500 deep. Some of these prey are also vertical migrators. The diet of Gulf sperm whales does not include species targeted by the commercial fisheries. INTRODUCTION Until fairly recently, little was known about the species of whales and dolphins (cetaceans) inhabiting the deep waters of the Gulf of Mexico. Most of the information available came from opportunistic sightings and occasional strandings. In the early 1990' s large-scale dedicated surveys were initiated to study the distribution and abundance of marine mammals in the deep Gulf. -
<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. -

Raineri, 86 98100 Messina, Italy ** ICRAM, Istituto per la Ricerca Scientifica Applicata al Mare, Via dei Casalotti, 300 00166 Roma -Italy Abstract Data on occurrence of Histioteuthis bonnellii and Histioteuthis reversa collected in the southern Tyrrhenian Sea from 1994 to 1998 during five trawl surveys of the Medits eight trawl survey of the Grund project are reported. The International bottom trawl survey (the MEDITS programme) has been designed from a European Commission’s initiative to produce biological data on the demersal resources along the coasts of the four Mediterranean countries of the European Union (Spain, France, Italy and Greece). The main objective was to obtain independent knowledge useful for the fishery management, in an area where it is difficult to follow in detail the exploitation patterns of the fishing fleets. In Italian seas, before 1985, there was no research at national level on biological aspect and assessment of demersal resources. Within the framework of the first national plan (1985-1988) of the Law 41/82, three main research groups to assess demersal resources were organized: Tyrrhenyan group, Adriatic and Ionian group and Sicily group. All the seas were covered, with the exception of Ionian part of Sicily. -

Lefkaditou1, P. Maiorano2 and Ch. Mytilineou1 1National Centre for Marine Research, Aghios Kosmas, Helliniko, 16604 Athens, Greece. E-mail: [email protected] 2Department of Zoology, University of Bari, via E.Orabona 4, 70125 Bari, Italy. E-mail: [email protected] Abstract The intensive exploitation of the continental shelf has lead to a search of new fisheries resources in deeper waters. Four seasonal experimental surveys were carried out on the deep-waters of the Eastern Ionian Sea by Greek and Italian commercial trawlers from September 1999 to September 2000.Potential targets included deepwater species of fishes, shrimps and cephalopods. During the 4 cruises, a total of 26 species of cephalopods in 10 families were recorded, including 10 oegopsid squids, 3 myopsid squids, 5 octopods, 2 cuttlefishes and 6 sepiolids. Deep-water trawling resulted in the finding of some uncommon species such as Ancistroteuthis lichtensteini, Ctenopteryx sicula and Galiteuthis armata, which were recorded for the first time in the study area. Extensions of depth range were recorded for several species. The results of multivariate analyses, based on Bray-Curtis similarity indices, showed the presence of two clear associations: one consisting of hauls carried out at depths 300-550 m, where Sepietta oweniana, Todaropsis eblanae and Loligo forbesi are the most abundant species, and another with deeper hauls (up to 770 m depth) dominated by Neorossia caroli, Pteroctopus tetracirrhus and Todarodes sagittatus. -
