“…Moreover, much of the ingested material exits the anus undigested after 1–2 hours and most of the gut contents consist of detritus, suggesting that amphioxus are indiscriminate suspension feeders ( Gosselck et al, 1978 ). A clear example of this indiscriminate filtering behaviour is the fact that several recent studies show how different species of amphioxus are capable of filtering microplastics present in the environment ( Cheng et al, 2023 ; Xiang et al, 2022 ).…”

Cephalochordates and tunicates represent the only two groups of invertebrate chordates, and extant cephalochordates – commonly known as amphioxus or lancelets – are considered the best proxy for the chordate ancestor, from which they split around 520 million years ago. Amphioxus has been an important organism in the fields of zoology and embryology since the 18th century, and the morphological and genomic simplicity of cephalochordates (compared to vertebrates) makes amphioxus an attractive model for studying chordate biology at the cellular and molecular levels. Here we describe the life cycle of amphioxus, and discuss the natural histories and habitats of the different species of amphioxus. We also describe their use as laboratory animal models, and discuss the techniques that have been developed to study different aspects of amphioxus.

“…of larger plastic debris (known as secondary MNPs) [6] , [7] . MNPs are widely distributed in terrestrial and aquatic ecosystems and their pollution is predicted to increase which will continue to pose greater risks to biota and ecosystem processes in various environments [1] , [4] , [8] , [9] . Given the ubiquity of MNPs, they are likely to be ingested by organisms through contaminated food, inhalation, or dermal contact from various exposure sources such as food, dust, cosmetics, medicine, clothing, etc.…”
