“…Our results for the structure of the penaeid shrimp ASC, PSC and GS are similar to those previously reported for P. japonicus (Lin, 1996) and for other crustacean species, including the spider crab, Notomithrax ursus (Woods, 1995), the Brazilian native prawn, M. carcinus (Lima et al, 2016) and three Antarctic shrimp species (N. lanceopes, N. antarcticus and C. antarcticus) (Storch et al, 2001). Most of these reports focused mainly on the relationship between the structure and dietary habits of each species.…”

“…Structural and morphological investigation of the GS has also been reported for many decapod species, e.g. Penaeus (Marsupenaeus) japonicus (Lin, 1996), Pleoticus muelleri (Díaz et al, 2008), Nematocarcinus lanceopes, Notocrangon antarcticus and Chorismus antarcticus (Muhammad et al, 2012), P. monodon and Metapenaeus ensis (Lin, 2000) and M. carcinus (Lima, et al, 2016). All these studies reported the same pattern of GS organization as an inverted-V, dome-like structure covered with numerous stacks of overlapping fine setae and located at the ventro-medial side of the PSC.…”

“…Particles too large to pass through the GC are conducted out of the PSCV through a separate channel to join the coarser material going directly into the intestine from the dorsal region of the ASC. This process has been described in detail for the river prawn Macrobrachium carcinus (Order Decapoda) (Lima et al, 2016) and the mountain shrimp Anaspides tasmaniae (Order Syncardia) (Wallis and Macmillan, 1998). Structural and morphological investigation of the GS has also been reported for many decapod species, e.g.…”

Unlike that of vertebrates, the penaeid shrimp stomach is of ectodermic origin and is thus covered by a cuticle that is sloughed upon molting. It is composed of two chambers, here called the anterior and posterior stomach chambers, ASC and PSC, respectively. The PSC contains a filtration structure variously called a pyloric filter, filter press, gastric filter or gastric sieve (GS), and the last of these will be used here. The GS resembles an elongated, inverted-V, dome-like, chitinous structure with a midline ridge that is integral to the ventral base of the PSC. The dome surface is covered with a carpet-like layer of minute, comb-like setae bearing laterally branching setulae. This carpet serves as a selective filter that excludes large partially digested food particles but allows smaller particles and soluble materials to enter hepatopancreatic ducts that conduct them into the shrimp hepatopancreas (HP), where further digestion and absorption of nutrients takes place. Although the GS function is well known, its exclusion limit for particulate material has not been clearly defined. Using histological and ultra-structure analysis, we show that the GS sieve pore diameter is approximately 0.2-0.7 µm in size, indicating a size exclusion limit of substantially less than 1 µm. Using fluorescent microbeads, we show that particles of 1 µm diameter could not pass through the GS but that particles of 0.1 µm diameter did pass through to accumulate in longitudinal grooves and move on to the HP, where some were internalized by tubule epithelial cells. We found no significant difference in these sizes between the species Penaeus monodon and Penaeus vannamei or between juveniles and adults in P. vannamei. This information will be of value for the design of particulate feed ingredients such as nutrients, therapeutic drugs and toxin-absorbing materials that may selectively target the stomach, intestine or HP of cultivated shrimp.

Gut evolution in early Cambrian trilobites and the origin of predation on infaunal macroinvertebrates: evidence from muscle scars in Mesolenellus

Trilobites are particularly common Cambrian fossils, but their trophic impact on the rapidly evolving marine ecosystems of that time is difficult to assess, due to uncertainties on how diverse their feeding habits truly were. Gut anatomy might help to constrain inferences on trilobite feeding ecology, but preservation of digestive organs is exceedingly rare. Muscle scars on the glabella, known as ‘frontal auxiliary impressions’ (FAIs), have been interpreted as evidence of the evolution of a pouch‐like organ with powerful extrinsic muscles (i.e. a crop) in some trilobites. Here we describe FAIs in Mesolenellus hyperboreus from Cambrian Stage 4 strata of North Greenland, which represents the oldest example of such structures and their first report in the Suborder Olenellina. Mesolenellus FAIs suggest that the crop in trilobites was clearly differentiated from the rest of the digestive tract, and essentially located under a hypertrophied glabellar frontal lobe. Reviews of the digestive anatomy of trilobite sister‐taxa and the glabellar morphology of the oldest‐known trilobites suggest that the gut of the trilobite ancestor was an essentially simple tract (i.e. no well‐differentiated crop) flanked laterally by numerous midgut glands. A crop first evolved in the Cambrian in groups like olenelloids and (later) paradoxidoids. Using ichnological evidence, we hypothesize that the emergence of olenelloids yields evidence for the evolution of predatory inclinations in a group of arthropods originally dominated by surface‐deposit‐feeders. By allowing the exploitation of a rapidly developing food source, infaunal animals, the diversification of feeding strategies in trilobites might partially explain their unparalleled evolutionary success.
