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. -
CEPHALOPODS 688 Cephalopods
click for previous page CEPHALOPODS 688 Cephalopods Introduction and GeneralINTRODUCTION Remarks AND GENERAL REMARKS by M.C. Dunning, M.D. Norman, and A.L. Reid iving cephalopods include nautiluses, bobtail and bottle squids, pygmy cuttlefishes, cuttlefishes, Lsquids, and octopuses. While they may not be as diverse a group as other molluscs or as the bony fishes in terms of number of species (about 600 cephalopod species described worldwide), they are very abundant and some reach large sizes. Hence they are of considerable ecological and commercial fisheries importance globally and in the Western Central Pacific. Remarks on MajorREMARKS Groups of CommercialON MAJOR Importance GROUPS OF COMMERCIAL IMPORTANCE Nautiluses (Family Nautilidae) Nautiluses are the only living cephalopods with an external shell throughout their life cycle. This shell is divided into chambers by a large number of septae and provides buoyancy to the animal. The animal is housed in the newest chamber. A muscular hood on the dorsal side helps close the aperture when the animal is withdrawn into the shell. Nautiluses have primitive eyes filled with seawater and without lenses. They have arms that are whip-like tentacles arranged in a double crown surrounding the mouth. Although they have no suckers on these arms, mucus associated with them is adherent. Nautiluses are restricted to deeper continental shelf and slope waters of the Indo-West Pacific and are caught by artisanal fishers using baited traps set on the bottom. The flesh is used for food and the shell for the souvenir trade. Specimens are also caught for live export for use in home aquaria and for research purposes. -
<I>Sthenoteuthis Oualaniensis</I>
BULLETIN OF MARINE SCIENCE, 71(2): 1105–1108, 2002 THE AGE AND GROWTH OF STHENOTEUTHIS OUALANIENSIS (CEPHALOPODA: OMMASTREPHIDAE) IN THE PACIFIC OCEAN Kaori Takagi, Takeru Kitahara, Naoki Suzuki, Junta Mori and Akihiko Yatsu Sthenoteuthis oualaniensis is distributed in the tropical and subtropical areas of the Pacific and the Indian Oceans. According to Nesis (1993), there is a complex population structure in S. oualaniensis, as is the case in many other ommastrephids and some loliginids. In the Pacific Ocean, there is the middle-sized squid which is a widespread and typical one (Nesis, 1993). Arkhipkin and Bizikov (1991) examined the statoliths of middle-sized female in the Indian Ocean and determined its growth. S. oualaniensis is, though, one of the most difficult species in the Ommastrephidae for the observation of statolith incre- ments due to the numerous occulting crystals and weak contrast in the increments (Uozumi, 1993). Using a newly developed heating technique in processing statoliths, we estimated the age and growth of S. oualaniensis, assuming the daily deposition of increments. MATERIALS AND METHODS Samples of S. oualaniensis were collected between September and December 1993 in the Pa- cific Ocean around the Hawaii and the Ogasawara (Bonin) Islands. We used the statoliths of 53 adults (112–284 mm in mantle length (ML), 21 males and 32 females) and 112 paralarvae (0.7– 13.5 mm in ML). The adults were captured by drift nets and jigs. The paralarvae were captured by bongo nets and a larval net. To examine the relationship between ML and age, we also used 6 other juveniles (39–50 mm in ML) captured using a dip net. -

Helminth Infection in the Short-Finned Squid Illex Coindetii (Cephalopoda, Ommastrephidae) Off NW Spain
DISEASES OF AQUATIC ORGANISMS Published September 14 Dis aquat Org Helminth infection in the short-finned squid Illex coindetii (Cephalopoda, Ommastrephidae) off NW Spain 'Laboratorio de Parasitologia, Facultad de Ciencias, Universidad de Vigo, Ap. 874 E-36200 Vigo, Spain 'Institute de Investigacions Marinas (CSIC),Eduardo Cabello 6, E-36208 Vigo, Spain ABSTRACT: A survey of parasites in 600 short-finned squid fllex coindetii (Verany. 1839) taken from 2 locations (north and south Galicia) off the northwestern Ibenan Peninsula revealed the presence of numerous somatoxenous helrninths. Three genera of Tetraphyllidean plerocercoids were represented (prevalences: Ph}~llobothriurn sp., 45.7%; Dinobothriunl sp., 0.8%; and Pelichnibothrium speciosum, 0.001 %); 1 Trypanorhynchidean metacestode was also present (Nybelinia vamagutll. 0.4 %). In addi- tion, larval nematodes of Anisakis simplex (L3) were recorded (10.6%). Abundance of infection was examined in relation to squid sex, standard length, maturity and locality. This analysis indicated that parasite infection was lower in the southern squids than in the northern squid group. Over the entire survey area, parasite infection showed a close positive correlation with host life-cycle, often with the greatest number of parasites among the largest and highest maturity individuals (>l8to 20 cm; matu- rlty stage V).

<I>Onychoteuthis</I> Lichtenstein, 1818
BULLETIN OF MARINE SCIENCE, 83(3): 481–529, 2008 NEW TAXA PAPER TWO NEW SPECIES AND A REVIEW OF THE SQUID GENUS ONYCHOTEUTHIS LICHTENSTEIN, 1818 (OEGOPSIDA: ONYCHOTEUTHIDAE) FROM THE PACIFIC OCEAN K. S. Bolstad ABSTRACT The onychoteuthid genusOnychoteuthis Lichtenstein, 1818 is in systematic disarray. The oldest species, Onychoteuthis banksii (Leach, 1817), is widely recognized as a species complex, with which two of the other commonly recognized three species—Onychoteuthis compacta (Berry, 1913) and Onychoteuthis borealijaponica Okada, 1927—and some 20 additional names have been all synonymized at one time. This study, a partial revision of the genus, redescribes O. banksii from the Atlantic Ocean; from the Pacific, O. compacta, O. borealijaponica, and Onychoteuthis meridiopacificaRancurel and Okutani, 1990, are redescribed, the name Onychoteuthis aequimanus Gabb, 1868, is resurrected, and two additional species are described: Onychoteuthis lacrima sp. nov., and Onychoteuthis prolata sp. nov. Several new species-level characters are examined in detail, compared, and reported for each species, including buccal morphology, tentacular club and hook morphology, chromatophore patterns on the mantle and tentacles, and photophore shape and size. The cosmopolitan tropical/temperate genus Onychoteuthis has long been recog- nized for its systematic instability (Kubodera et al., 1998; Vecchione et al., 2003). Onychoteuthis banksii (Leach, 1817) has been a catch-all name for many morpho- logically similar taxa since its description nearly 200 yrs ago (Vecchione et al., 2003), including: two of the additional three species generally recognized by recent authors—Onychoteuthis compacta (Berry, 1913) and Onychoteuthis borealijaponica Okada, 1927, at various times—and about 20 additional nominal species (see e.g., Pfeffer, 1912; Adam, 1952). -

Did a Shark Clash with Large Squid and Live to Tell the Tale? 12 June 2020, by Angela Nicoletti
Did a shark clash with large squid and live to tell the tale? 12 June 2020, by Angela Nicoletti Oceanic whitetips reside mostly in remote part of the ocean where food is scarce. This has made them difficult to study. Once considered one of the most abundant shark species in the world, they are now listed as threatened under the Endangered Species Act. For more than a decade, Papastamatiou and Chapman have studied these enigmatic sharks. Using tracking tags and special sensors that record swim speed, acceleration and depth, they've been able to uncover details about their behavior. Data has shown they dive deep. Very deep. Sometimes to depths of 1,000 feet below the Credit: Deron Verbeck surface. Researchers believe one of the reasons they do this is to forage for food, including smaller squid. They've even been observed following pods of pilot whales. Underwater photographer Deron Verbeck was diving off the coast of Kona, Hawaii when he When any animal enters those great depths, spotted an oceanic whitetip shark with strange though, they enter the territory of the phantom of scarring across its head and back. He snapped a the deep—the giant squid. photo of the shark with its scarring pattern of circles and dots that didn't look like teeth marks. The team isn't sure what exactly went down, but they believe the squid was at least the same size Verbeck brought the photo to Yannis as the oceanic whitetip—between 6 and 7 feet in Papastamatiou, Demian Chapman and Heather length—but possibly larger. -
