“…Currently, there is no evidence to suggest that NPs have been detected in cephalopods. However, microplastics (MPs, 1 μm–5 mm) have been detected in wild cephalopods Sepia officinalis ( Oliveira et al, 2020 ) , Octopus vulgaris ( Pedà et al, 2022 ), Octopus variabilis ( Gong et al, 2021 ), Amphioctopus fangsiao ( Yu et al, 2022a ), Dosidicus gigas , Abralia veranyi and Vampyroteuthis infernalis ( Ferreira et al, 2022 ). Given that the size of NPs are smaller than MPs, NPs are more easily ingested and difficult to detect.…”

Nanoplastics (NPs), as a new type of pollutant with a size small than 1 μm, are ubiquitous and harmful to organisms. There has been an increasing amount of research concerning the effects of NPs on organisms over recent years, especially on aquatic animals. However, there is a limited study on the impact of NPs on mollusk cephalopods. In this research, Sepia esculenta, belonging to Cephalopoda, Coleoidea, Sepioidea, was selected to explore the effects caused by NPs exposure. The S. esculenta larvae were exposed to polystyrene NPs (PS-NPs) with diameter 50 nm (100 mg/L) for 4 h. The detection of oxidative stress biomarkers displayed an obvious increase in SOD (superoxide dismutase) activity and MDA (malondialdehyde) level. Then, RNA-Seq was performed to explore the oxidative stress response at mRNA level. The transcriptome analysis demonstrated that the expression of 2,570 genes was affected by PS-NPs. Besides, the signaling pathways of ribosome, ribosome biogenesis in eukaryotes, proteasome, and MAPK were enriched. This study not only provides novel references for understanding the mechanisms of oxidative stress response induced by NPs, but also reminds us to follow with interest the influence of acute exposure to NPs.

“…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.
