The present study deals with the first record of Sternaspis scutata (Ranzani, 1817); three specimens were obtained, one was located inside the samples, in 2018, at shallow depths, by trawling net of a fishing activity in front of Port Said. The other two specimens were collected from Suez Gulf (Gabal El Zeit region 2017) using benthic samples. Abbr...

... cf. S. nuda in the NW Pacific covering a distance of about 9600 km across the Pacific Ocean [252]. Sternaspis scutata is apparently the most widely reported name in the past but was recorded also more recently from the Cochin Estuary (SW India) [270], the English Channel [273], where it was considered an invasive species, the west coast of India (Arabian Sea) [271], the Sundarban Mangroves (Bengal Sea) [269], Jiaouzhou Bay (Yellow Sea) [268,274], and the Gulf of Suez (Red Sea) [272]. The latter record could be the result of Anti-Lessepsian migration, i.e., Mediterranean species entering the Red Sea via the Suez Canal [275]. ...
Sedentarian annelids are a diverse and heterogeneous group of marine worms representing more than 8600 species gathered in ca. 43 families. The attention brought to these organisms is unevenly distributed among these families, and the knowledge about them sometimes scarce. We review here the current knowledge about the families Acrocirridae, Cirratulidae (including Cteno-drilidae), Cossuridae, Longosomatidae, Paraonidae, and Sternaspidae in terms of biodiversity as well as the evolution of the taxonomy and systematics of each group. We present the challenges faced when studying these organisms and compare methodologies across groups and perspectives in future research.
... Among the approximately 46 polychaeta species classified as NIS in Brazil (Rodrigues et al., 2020), eight are invasive exotic species (I3N, 2018). To date, non-indigenous Sternaspidae has not been recorded on the Brazilian coast, but in the UK (Townsend et al., 2006;Shelley et al., 2008), India (Jose et al., 2014) and Egypt (Abdelnaby, 2020), Sternaspis scutata (Ranzani, 1817) has been recorded as a non-native or invasive polychaeta. ...
The introduction of non-indigenous marine species in new habitats is generally associated with ships arriving at ports, driven by species transported in ballast water and sediment and biofouling communities on ship hulls, drifting object and underwater surfaces in dock areas. The present paper reports the record of the specie Sternaspis aff. nana in the Atlantic Ocean, discussing its possible conservation status and method of arrival to Brazil. Sediments samples were collected in the external area (11 m depth) of the Suape Harbor (Brazil) in February 2018. Two individuals of Sternaspis aff. nana were recorded, representing the first record of this species in the Southwest Atlantic Ocean. The way S. aff. nana arrived in Brazilian waters cannot be easily determined, the short-lived lecithotrophic larvae of sternaspids suggest that the specimens found in Suape have arrived in ballast sediment. An increase in trade between Brazil and Asian countries since the 2000s has led to that more ships coming from China having arrived in Brazilian harbors. The arrival of S. aff. nana, originally described in the South China Sea, in the Suape harbor area may have resulted from this intense movement of ships between China and Brazil.
