“…Serejo et al, (2006) B. giganteus is found in the Indian, Pacific and western Atlantic oceans, in the latter case, between Florida and Brazil (Serejo et al, 2006). Similar to the present study, Cintra et al (1998) Loyola e Silva (1999) concluded that B. miyarei occurs throughout Brazilian shelf and slope. The species was collected previously at depths of 312-458 m in the Amapá coast, and 320 m in the Pará coast (Cintra et al, 1998), although it was captured in shallower waters in the Northeast, in Ceará (80 m) and Rio Grande do Norte (22 m).…”

“…A number of past studies have focused on Brazilian isopods, identifying a number of new occurrences in the Alagoas state (Loyola e Silva et al, 1994), describing new species from southern Brazil (Araújo & Buckup, 1996), identifiying a parasitic species in the Paraná State (Oliveira & Masunari, 2006), re-describing a species from the state of Minas Gerais (Thatcher Research, Society and Development, v. 9, n. 8, e974986843, 2020(CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i8.6843 et al, 2009 and recording a number of terrestrial isopods from the Brazilian Atlantic Fores (Magrini et al, 2011). Other researches focused on the genus Bathynomus, such as that of Cintra et al (1998) on the Northern coast of Brazil, Loyola e Silva (1999) in the Rio Grande do Sul state, and Magalhães & Young (2003) and Serejo et al (2006) in Southeastern Brazil.…”

The present study focuses on the distribution and abundance of the giant isopod community, based on specimens collected using the bottom shrimp trawling on the Amazon continental shelf during fishery surveys, at depths between 81 m and 626 m, conducted during the REVIZEE/Score-North Program between 1996 and 1998. The study area is located within the exclusive economic zone of Brazil, between the States of Amapá and Pará. In total, 170 specimens were collected, distributed in the two species Bathynomus giganteus (n = 49) and Bathynomus miyarei (n = 121), in which 54% of the material were collected in the northern and 46% in the southern sector of the study area. B. miyarei was considered to be the dominant species in both sectors, whereas B. giganteus was uncommon in the northern sector, but abundant in the southern sector. Both species preferred gravelly bottoms in the northern sector, and gravelly sand in the southern sector and were more abundant during the dry season in the northern sector, but during the rainy season in the southern sector. The smallest female B. giganteus was collected in the northern sector, and the largest in the southern sector, whereas both the largest and the smallest female B. miyarei were captured in the southern sector. All the male specimens collected in this study were captured in the northern sector.

“…Currently, its distribution is considered as restricted to the Atlantic Ocean and extends from 31 N, adjacent to the State of Georgia, USA (Lowry & Dempsey, 2006), to 30 S, off the coast of Rio Grande do Sul, Brazil (Soto & Mincarone, 2001). Along the Brazilian coast (Soto & Mincarone, 2001), Bathynomus miyarei has been collected from Amapá (4 N) (Cintra et al, 1998) to Rio Grande do Sul (30 S), between 230 and 800 m deep (Magalhães & Young, 2003).…”

1. This study aimed to determine biological and distributional aspects of deep-sea giant isopods Bathynomus giganteus and Bathynomus miyarei to assess their extinction risk. 2. Bathynomus giganteus (663 specimens) and B. miyarei (649 specimens) were collected during five research cruises involving 265 h of sampling effort during 32 fishing operations of circular pots, baited traps, ranging from 400 and 1,000 m deep, between 26 and 29 S adjacent to the Brazilian coast. 3. A trend towards larger, sexually mature animals in shallower regions was observed for both species, and depth was the most important environmental variable influencing the animals' distribution. 4. Bathynomus giganteus were collected between 600 m and 1,000 m depth, while the highest densities of B. miyarei were at shallower depths, between 400 and 600 m. 5. The sex ratio was equal for both B. giganteus and B. miyarei for different seasons, latitudes and bathymetries. 6. The sexual maturity of B. giganteus was estimated at 340-345 mm total length for males and between 280-290 mm for females. Bathynomus miyarei males' sexual maturity was estimated in the 225-230 mm size class. 7. Bathynomus giganteus showed reproductive activity throughout the year. 8. The longevity of B. giganteus was estimated at 6 years for males and 7.7 years for females. The longevity of B. miyarei was estimated at 9 years for males and 6 years for females. 9. Extinction risk assessment for B. giganteus, which has a greater latitudinal and bathymetric distribution, was evaluated as Least Concern. However, B. miyarei was evaluated in the Data Deficient category.
