TL;DR: In this article, the biodiversity and distribution of soft bottom peracarid crustaceans were analyzed in the south part of Canakkale Strait, a very important biological corridor between the Mediterranean and the Black Sea.
Abstract: The biodiversity and distribution of soft-bottom peracarid crustaceans were analyzed in the south part of Canakkale Strait, a very important biological corridor between the Mediterranean and the Black Sea. Samples were collected seasonally from 11 coastal stations at depths ranging from 10 to 22 m. Moreover, qualitative samples were collected in summer from 7 stations (40 - 83 m depth) located in the middle part of the Strait. A total of 110 species were identified. Amphipods were the dominant group both in terms of species richness and abundance. Apocorophium acutum, Phtisica marina and Microdeutopus versiculatus were the most abundant species. A large number of rare species was recorded, leading to very low similarity values among stations. Six different feeding types were detected, with surface deposit feeders being the dominant one in the area. Significant differences in abundances and assemblage structure were detected along the eastern and western coasts of the Strait that could be attributed to food supply and sediment composition, depending on bottom current velocities. Possible relations of peracarids with the hydrological regime of the area are also discussed.
TL;DR: A new fossil species, Makrokylindrus itoi, is described from Plio-Pleistocene Japan, representing the first Diastylidae and fourth crown group cumacean fossil, highlighting the need to reevaluate the fossil record of cumaceans due to taxonomic bias and small size.
Abstract: Abstract Comma shrimp, or cumaceans, are diverse benthic crustaceans, yet they are one of the groups with the poorest fossil record, hindering our understanding of the evolution of the group in deep time. Here, we describe a new species of fossil comma shrimp, Makrokylindrus itoi sp. nov., from the Plio‐Pleistocene of Japan. The singular fossil is exceptionally preserved, including details of the carapace, cuticle, and some appendages, and it represents the first known fossil of the family Diastylidae and only the fourth fossil crown group cumacean known to date. We suggest that the scarce and sparsely known fossil record of cumaceans likely reflects a lack of recognition due to their small size and unfamiliar anatomy, making fossil cumaceans easy to misidentify, be confused with crustacean larvae of unknown affinities, or be interpreted as fragments of other crustaceans (taxonomic bias), rather than a lack of fossilization potential (taphonomic bias).

TL;DR: Deep-sea Caprellidae from Galicia, NW Iberian Peninsula, includes a new genus and species descriptions.
Abstract: This dataset contains the digitized treatments in Plazi based on the original journal article Guerra-García, José M., Tato, Ramiro, Moreira, Juan (2018): Caprellidae (Crustacea: Peracarida: Amphipoda) from deep-sea waters off Galicia (NW Iberian Peninsula) with the description of a new genus and three new species. Zootaxa 4532 (2): 151-202, DOI: https://doi.org/10.11646/zootaxa.4532.2.1
TL;DR: A new deep-sea species of Bathybirubius is described from the Bay of Campeche, SW Gulf of Mexico, at 2,385m depth, characterized by distinct morphological features, representing the second species in the genus and the first record for the Gulf of Mexico.
Abstract: The genus Bathybirubius Senna, 2010 was erected to receive the species B. margaretae Senna, 2010 from Brazilian deep—sea waters. The present study describes and illustrates in detail a new deep—sea species of Bathybirubius which represents the second species in the genus and the first record for the Gulf of Mexico. The new species was collected from soft bottoms offshore Veracruz State, Mexico, in the Bay of Campeche, SW Gulf of Mexico, at 2,385 m depth. The new species is characterized by head length, accessory flagellum of antenna 1, antenna flagellum 2, mandibular palp, coxae 1 and 2, merus of pereopods 3 and 4, basis of pereopod 7, epimeron 3, and notch of telson. A comparative table showing primary features of the only 2 Bathybirubius species described until now is also included.
