First Occurrence

The first occurrence of a giant squid Architeuthis sp. specimen in Portuguese waters is noted and another reference set of biological and biometrical data provided which may in future be used in conjunction with others to further elucidate important aspects of the identity, biology and ecology of the species. The fact that the specimen is a male is relevant, since males have been much less frequent in the reports in the scientific literature than have females. Additionally, this is the most southerly report of a male known to have occurred in the Atlantic Ocean.

Chaetognaths are composed by six families and among them Spadellidae is strictly benthic. This study reports the first occurrence of Paraspadella nana Owre, 1963 in the coastal zone located in the northern region of Espírito Santo state (19°51’12” S, 40°02’45” W). This species was first recorded from the oceanic region of southeastern Florida and now it was recorded off the coast of Espírito Santo for the first time expanding its distribution to the southwest Atlantic Ocean.

A Current

The word « hypoxia » has recently come to the attention of the general public in two occasions, the Nobel Prize in Medicine or Physiology in 2019 and the recent COVID-19pandemics. In the academic environment, hypoxia is a current topic of research in biology, physiology and medicine: in October 2020, there were more than 150,000 occurrences of "hypoxia" in the PubMed database. However, the first occurrence is dated in 1945, while the interest for the effects of oxygen lack on the living organisms started in the mid 19thcentury, when scientists explored high altitude regions and mainly used the terms "anoxia" or "anoxemia". I therefore made an Internet research through multiple databases to look for the first appearance of "hypoxia" and related terms "hypoxemia" and "hypoxybiosis" in the scientific literature published in English, German, French, Italian and Spanish. Viault and Jolyet used "Hypohématose" in 1894, but this word was never used since. Hypoxybiosis appeared first in 1909 in Germany, then hypoxemia in 1923 in Austria and hypoxia in 1938 in Holland. It was then exported to United States where it appeared in 1940 in cardiology and anesthesiology. The clinical distinction between anoxia and hypoxia was clearly defined by Carl Wiggers in 1941. Hypoxia (decrease in oxygen), by essence variable in time and in localization in the body, in contrast with anoxia (absence of oxygen), illustrates the concept of homeodynamics that defines a living organism as a complex system in permanent instability, exposed to environmental and internal perturbations.

Paralacydoniid polychaetes belonging to the genus Paralacydonia Fauvel 1913 were collected during the REVIZEE Program/South Score/Benthos ("Avaliação do Potencial Sustentável dos Recursos Vivos na Zona Econômica Exclusiva") on the outer shelf and continental slope off the south-southeastern coast of Brazil between 156 and 400 m depth. This new report extends the known geographic distribution of the family, which had previously been recorded in the North Atlantic as far as the Gulf of Mexico. Paralacydonia is here treated as monotypic; P. mortenseni Augener 1924 and P. weberi Horst 1923 are considered synonyms of Paralacydonia paradoxa Fauvel 1913.

First Occurrence

Three individuals of small, young giant squidArchiteuthis duxwere caught in or near Japanese coastal waters during April–June 2013. The first occurrence of a young individual of 140.8 mm dorsal mantle length with a total weight of 44.81 g was recorded on the coast off Uchinoura, Kagoshima, Kyushu Island, southern Japan. The remaining two young individuals, both measuring 332.0 mm in dorsal mantle length with total weights of 390.63 and 356.95 g respectively, were caught on the coast off Hamada, Shimane, south-western Sea of Japan. Most morphological traits of all the specimens were consistent with those ofA. dux, which was supported by further genetic analysis. Here we present some morphological traits of young giant squids with morphometric data and photographs.

During the study of the Carcinofauna of the Bahian Coast, some Brachyura Portunidae were found. Some of these animals were Callinectes arcuatus Ordway, 1863 which has its distribution restricted to the Pacific Ocean, from California to Peru and the Galapagos Islands. This is the first occurrence of this species reported from the Atlantic Ocean and the Brazilian Coast (Bahia, 38º50'Wand 12º50'S).

We describe the first species of the genus Paraleucilla Dendy 1892 from the Atlantic Ocean. P. magna sp. nov. is characterized by the presence of triactines composing the atrial skeleton and the absence of giant diactines, which are characteristic of P. cucumis (Haeckel 1872), a species from Australia, the only known Paraleucilla that also presents atrial triactines. P. magna sp. nov. is the most abundant calcareous sponge in Rio de Janeiro State (Brazil), and shows a strong seasonality, disappearing in autumn.

This communication is the first report of the occurrence of the order Mormonilloida (Mormonilla phasma) in the tropical Southwestern Atlantic Ocean. Female individuals were found in surface waters from the shelf break state of Rio Grande do Norte (Northeastern Brazil) and between depths of 60 and 100 m in the epipelagic layer around the St. Peter and St. Paul Archipelago (equatorial Atlantic). This finding extends the vertical limits for this species.

First Occurrence

Copepod crustaceans of the genusGaussiainhabit open ocean waters in epipelagic and bathypelagic zones from 0 to 5000 m. They show high-speed vertical migration and bioluminescent characteristics. In the Atlantic Ocean only the speciesG. asymmetricaBjörnberg T. K. S. & Campaner, 1988 andG. princeps(Scott T., 1894) have been recorded previously. We report the first occurrence of the rarely recordedG. intermediaDefaye, 1998 for the Atlantic off Brazil. The specimens were collected around the Rocas Atoll (3°51′S 33°49′W), through the ABRAÇOS (Acoustic along the BRazilian COast) project on board R/V “Antea” in October 2015, using a micronekton net (mesh size 1 mm) and oblique hauls. Five specimens were collected at Rocas Atoll, in depths of 510-525 m. This finding expands the global distribution ofG. intermediaand is the first occurrence in the Atlantic Ocean, updating the checklist of meso-bathypelagic copepods for Brazilian waters.
