  • 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.

  • Aspects of the Natural History of Pelagic Cephalopods of the Hawaiian Mesopelagic-Boundary Region 1
    Pacific Science (1995), vol. 49, no. 2: 143-155 © 1995 by University of Hawai'i Press. All rights reserved Aspects of the Natural History of Pelagic Cephalopods of the Hawaiian Mesopelagic-Boundary Region 1 RICHARD EDWARD YOUNG 2 ABSTRACT: Pelagic cephalopods of the mesopelagic-boundary region in Hawai'i have proven difficult to sample but seem to occupy a variety ofhabitats within this zone. Abralia trigonura Berry inhabits the zone only as adults; A. astrosticta Berry may inhabit the inner boundary zone, and Pterygioteuthis giardi Fischer appears to be a facultative inhabitant. Three other mesopelagic species, Liocranchia reinhardti (Steenstrup), Chiroteuthis imperator Chun, and Iridoteuthis iris (Berry), are probable inhabitants; the latter two are suspected to be nonvertical migrants. The mesopelagic-boundary region also contains a variety of other pelagic cephalopods. Some are transients, common species of the mesopelagic zone in offshore waters such as Abraliopsis spp., neritic species such as Euprymna scolopes Berry, and oceanic epipelagic species such as Tremoctopus violaceus Chiaie and Argonauta argo Linnaeus. Others are appar­ ently permanent but either epipelagic (Onychoteuthis sp. C) or demersal (No­ totodarus hawaiiensis [Berry] and Haliphron atlanticus Steenstrup). Submersible observations show that Nototodarus hawaiiensis commonly "sits" on the bot­ tom and Haliphron atlanticus broods its young in the manner of some pelagic octopods. THE CONCEPT OF the mesopelagic-boundary over bottom depths of the same range. The region (m-b region) was first introduced by designation of an inner zone is based on Reid et al. (1991), although a general asso­ Reid'sfinding mesopelagic fishes resident there ciation of various mesopelagic animals with during both the day and night; mesopelagic land masses has been known for some time.

  • Distribution and Behaviour of Deep-Sea Benthopelagic Fauna Observed Using Towed Cameras in the Santa Maria Di Leuca Cold-Water Coral Province

Orabona 4, 70125 Bari, Italy 2Department of Geological Science and Geotechnology, University of Milano-Bicocca, Piazza della Scienza 4, 20126 Milano, Italy ABSTRACT: Using a towed camera system, a total of 422 individuals belonging to 62 taxa (includ- ing 33 identified species) were counted in the Santa Maria di Leuca (SML) coral province (Mediterranean Sea). Our findings update the knowledge of the biodiversity of this area and of the depth records of several species. The presence of coral mounds mostly in the north-eastern sector of the SML coral province seems to influence the large scale distribution of the deep-sea ben- thopelagic fauna, playing the role of attraction-refuge with respect to the barren muddy bottoms where fishing occurs in northern areas. Multiple Correspondence Analysis identified 3 main taxa groups: (1) rather strictly linked to the bottom, resting or moving on the seabed, often sheltering and feeding; (2) mostly swimming in the water column and mostly observed on rugged bottoms; and (3) actively swimming or hovering near the seabed. The behavioural patterns largely related to activity and position of the fauna seem to determine their small-scale distribution. The effects of different benthic macrohabitats appear to be less important and the depth within the bathymetric range examined even less so.

    DIET OF FREE-RANGING AND STRANDED SPERM WHALES (Physeter macrocephalus) FROM THE GULF OF MEXICO NATIONAL MARINE FISHERIES SERVICE CONTRACT REPORT Submitted to: Dr. Keith D. 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.

Robison Fall, 2009 Defensive Behaviors of Deep-sea Squids: Ink Release, Body Patterning, and Arm Autotomy © 2009 by Stephanie Lynn Bush ABSTRACT Defensive Behaviors of Deep-sea Squids: Ink Release, Body Patterning, and Arm Autotomy by Stephanie Lynn Bush Doctor of Philosophy in Integrative Biology University of California, Berkeley Professor Roy L. Caldwell, Chair The deep sea is the largest habitat on Earth and holds the majority of its’ animal biomass. Due to the limitations of observing, capturing and studying these diverse and numerous organisms, little is known about them. The majority of deep-sea species are known only from net-caught specimens, therefore behavioral ecology and functional morphology were assumed. The advent of human operated vehicles (HOVs) and remotely operated vehicles (ROVs) have allowed scientists to make one-of-a-kind observations and test hypotheses about deep-sea organismal biology. Cephalopods are large, soft-bodied molluscs whose defenses center on crypsis. Individuals can rapidly change coloration (for background matching, mimicry, and disruptive coloration), skin texture, body postures, locomotion, and release ink to avoid recognition as prey or escape when camouflage fails. Squids, octopuses, and cuttlefishes rely on these visual defenses in shallow-water environments, but deep-sea cephalopods were thought to perform only a limited number of these behaviors because of their extremely low light surroundings.

The aims of this research to identification of shell morphological characters of paper Nautiluses were collected at 1,000 m depth. The results showed that out of all the samples successfully collected during the course of the study (March till December 2016), only 6 specimens were found at 70-80 depth, with 4 of those species are egg-laying, and the other 2 are not. From the 6 species found, 2 were Argonauta argo with average shell length of 34.05 mm, shell width of 22.20 mm, and average aperture width of 11.15 mm. A. argo is known to possess 8 tentacles, 4 long and 2 short appendages. The shell color is brighter than that of A. hians, with flatter shell and two strips of keels located near each other along the dorsal and soft side, along ventral side thickens and sharpens. A. hians possess average shell length of 47.02 mm, shell width of 33.07 mm and aperture width of 21.30 mm.
