“…In Monterey Bay, California, Choy et al ( 2019) also observed a similar pattern: a peak concentration of MPs in the mesopelagic zone at a range of 200-600 m depth. Additionally, the size of MPs ingested was also influenced by the depth in which species were caught (Ferreira et al, 2022). Argyropelecus sladeni ingested the longest MPs, whereas S. diaphana ingested significantly smaller MPs, coinciding with surveys investigating MP size in the water column (Dai et al, 2018;Zobkov et al, 2019).…”

“…MPs incorporation into marine snow is hypothesised to be the main sinking mechanism for buoyant polymers (Kvale et al, 2020). Additionally, many deep-sea species undertake epipelagic vertical migrations to feed (Eduardo et al, 2020a) and may act as biological plastic transporter whenever contaminated with MPs (Ferreira et al, 2022). Although the role of mesopelagic fishes in the vertical movement of MPs in the water column has been proposed, it is still not well understood (Lusher et al, 2016;Savoca et al, 2021).…”

“…Examples include, microplastics in the water, adherent to, or ingested by the prey. Evidence for microplastic ingestion has been published for wild and cultured cuttlefish (Sepia officinalis, Oliveira et al, 2020), common octopus (Octopus vulgaris, Pedà et al, 2022), jumbo squid (Dosidicus gigas: Braid et al, 2012;Rosas-Luis, 2016), vampire and mid-water squid (V. infernalis and Abralia veranyi, Ferreira et al, 2022). Although no adverse effects are reported, the potential for harm, particularly from obstruction of the ducts linking the caecum and digestive gland is considerable (for discussion see Oliveira et al, 2020).…”

Methodological considerations in studying digestive system physiology in octopus: limitations, lacunae and lessons learnt

2022

Current understanding of cephalopod digestive tract physiology is based on relatively “old” literature and a “mosaic of data” from multiple species. To provide a background to the discussion of methodologies for investigating physiology we first review the anatomy of the cephalopod digestive tract with a focus on Octopus vulgaris, highlighting structure-function relationships and species differences with potential functional consequences (e.g., absence of a crop in cuttlefish and squid; presence of a caecal sac in squid). We caution about extrapolation of data on the digestive system physiology from one cephalopod species to another because of the anatomical differences. The contribution of anatomical and histological techniques (e.g., digestive enzyme histochemistry and neurotransmitter immunohistochemistry) to understanding physiological processes is discussed. For each major digestive tract function we briefly review current knowledge, and then discuss techniques and their limitations for the following parameters: 1) Measuring motility in vitro (e.g., spatiotemporal mapping, tension and pressure), in vivo (labelled food, high resolution ultrasound) and aspects of pharmacology; 2) Measuring food ingestion and the time course of digestion with an emphasis on understanding enzyme function in each gut region with respect to time; 3) Assessing transepithelial transport of nutrients; 4) Measuring the energetic cost of food processing, impact of environmental temperature and metabolic rate (flow-through/intermittent respirometry); 4) Investigating neural (brain, gastric ganglion, enteric) and endocrine control processes with an emphasis on application of molecular techniques to identify receptors and their ligands. A number of major knowledge lacunae are identified where available techniques need to be applied to cephalopods, these include: 1) What is the physiological function of the caecal leaflets and intestinal typhlosoles in octopus? 2) What role does the transepithelial transport in the caecum and intestine play in ion, water and nutrient transport? 3) What information is signalled from the digestive tract to the brain regarding the food ingested and the progress of digestion? It is hoped that by combining discussion of the physiology of the cephalopod digestive system with an overview of techniques and identification of key knowledge gaps that this will encourage a more systematic approach to research in this area.
