“…Despite its broad dietary range (Figure 8), it shows a prominent level of selectivity for larger mobile epifaunal prey items. This high level of flexibility in its trophic ecology might contribute to its very wide distribution on European coasts (Campos et al, 2009). In order to feed on diverse prey taxa, adult C. crangon are capable of employing a variety of methods ( Figure 8) including (camouflage-assisted) ambush predation (Gibson et al, 1995;Pinn & Ansell, 1993;Siegenthaler, Mastin, Dufaut, Mondal, & Benvenuto, 2018), gulping behaviour (Tiews, 1970) and scavenging ( Figure 8; Ansell et al, 1999;Price, 1962).…”

A thorough understanding of ecological networks relies on comprehensive information on trophic relationships among species. Since unpicking the diet of many organisms is unattainable using traditional morphology‐based approaches, the application of high‐throughput sequencing methods represents a rapid and powerful way forward. Here, we assessed the application of DNA metabarcoding with nearly universal primers for the mitochondrial marker cytochrome c oxidase I in defining the trophic ecology of adult brown shrimp, Crangon crangon, in six European estuaries. The exact trophic role of this abundant and widespread coastal benthic species is somewhat controversial, while information on geographical variation remains scant. Results revealed a highly opportunistic behaviour. Shrimp stomach contents contained hundreds of taxa (>1,000 molecular operational taxonomic units), of which 291 were identified as distinct species, belonging to 35 phyla. Only twenty ascertained species had a mean relative abundance of more than 0.5%. Predominant species included other abundant coastal and estuarine taxa, including the shore crab Carcinus maenas and the amphipod Corophium volutator. Jacobs’ selectivity index estimates based on DNA extracted from both shrimp stomachs and sediment samples were used to assess the shrimp's trophic niche indicating a generalist diet, dominated by crustaceans, polychaetes and fish. Spatial variation in diet composition, at regional and local scales, confirmed the highly flexible nature of this trophic opportunist. Furthermore, the detection of a prevalent, possibly endoparasitic fungus (Purpureocillium lilacinum) in the shrimp's stomach demonstrates the wide range of questions that can be addressed using metabarcoding, towards a more robust reconstruction of ecological networks.

“…Different populations of caridean species occupying different habitats can be locally adapted to or affected by different sets of environmental conditions (Ituarte et al 2007, Campos et al 2009). Though many studies have reported the presence of P. macrodactylus in different habitats around the world, the available information regarding life history and population traits is scarce and fragmentary ( Table 2).…”

SUMMARY: The invasive oriental shrimp Palaemon macrodactylus has been extensively recorded around the world, mainly in estuarine zones. In this study, the life history of this species was studied in Mar del Plata harbour (Argentina), a fully marine area where a stable and dense population has been established. Growth, sex proportion, morphological relationships, size at maturity and reproductive cycle were analysed between March 2007 and March 2009. A total of 9 and 7 modal classes (M1-M9) were detected in the size frequency distributions of females and males, respectively. The modes of both sexes were the same until M4 but from M5 to M7 females were larger than males. The life span was about one year with a clear seasonal growth. Recruitment and reproductive periods were recorded from December to March and October to March, respectively. The total sex ratio was biased to females. Nevertheless, a clear predominance of males was observed in classes smaller than 5.25 mm carapace length (CL). Females reached maturity at a larger size in spring to early summer (October-January) than in late summer (February-March); the estimated sizes for 50% sexual maturity were 6.79 mm and 5.91 mm CL, respectively. The results showed great differences from a presumably native estuarine population (Japan), such as shorter life span, smaller maximum size and smaller size at maturity.Keywords: life history, growth, intraspecific variability, invasive species, Caridea, reproduction. RESUMEN: CaraCterístiCas del CiClo vital del Camarón estuarino invasor Palaemon macrodactylus (Caridea: Palaemonidae) en un ambiente marino (mar del Plata, argentina). -El camarón oriental invasor Palaemon macrodactylus ha sido ampliamente documentado, principalmente en estuarios, alrededor del mundo. En este trabajo el ciclo de vida fue estudiado en el Puerto de Mar del Plata (Argentina), donde se registró una población estable y abundante en un ambiente netamente marino. Entre marzo de 2007 y marzo de 2009 se estudiaron: el crecimiento, la proporción de sexos, relaciones morfológicas, la talla de madurez y el ciclo reproductivo. A partir de las distribuciones de frecuencia de tallas se detectó un total de 7 y 9 clases modales (M1-M9) para machos y hembras respectivamente. Las modas de ambos sexos fueron iguales hasta la M4, mientras que en las M5-M7, las hembras fueron mayores. El tiempo de vida estimado fue de un año, con un crecimiento claramente estacional. El reclutamiento y el período reproductivo fueron registrados entre diciembre y marzo y entre octubre y marzo respectivamente. La relación de sexos fue sesgada hacia las hembras. Sin embargo, en las tallas menores a 5.25 mm de LC los machos fueron mayoría. Las hembras alcanzaron la madurez a una talla mayor en primavera/ inicio del verano (octubre-enero) que en el verano tardío (febrero-marzo). La talla del 50% de madurez estimada para cada período fue 6.79 mm y 5.91 mm de LC respectivamente. Los resultados mostraron grandes diferencias con una población estuarial presumiblemente del sitio de orige...

Many bio-inspired robots have been developed so far after careful investigation of animals' locomotion. To successfully apply the locomotion of natural counterparts to robots for efficient and improved mobility, it is essential to understand their principles. Although a lot of research has studied either animals' locomotion or bio-inspired robots, there have only been a few attempts to broadly review both of them in a single article. Among the millions of animal species, this article reviewed various forms of aquatic locomotion in arthropods including relevant bio-inspired robots. Despite some previous robotics research inspired by aquatic arthropods, we found that many less-investigated or even unexplored areas are still present. Therefore, this article has been prepared to identify what types of new robotics research can be carried out after drawing inspiration from the aquatic locomotion of arthropods and to provide fruitful insights that may lead us to develop an agile and efficient aquatic robot.
