Southeast (SE) Asia is a highly biodiverse region, yet it is also estimated to cumulatively contribute a third of the total global marine plastic pollution. This threat is known to have adverse impacts on marine megafauna, however, understanding of its impacts has recently been highlighted as a priority for research in the region. To address this knowledge gap, a structured literature review was conducted for species of cartilaginous fishes, marine mammals, marine reptiles, and seabirds present in SE Asia, collating cases on a global scale to allow for comparison, coupled with a regional expert elicitation to gather additional published and grey literature cases which would have been omitted during the structured literature review. Of the 380 marine megafauna species present in SE Asia, but also studied elsewhere, we found that 9.1 % and 4.5 % of all publications documenting plastic entanglement (n = 55) and ingestion (n = 291) were conducted in SE Asian countries. At the species level, published cases of entanglement from SE Asian countries were available for 10 % or less of species within each taxonomic group. Additionally, published ingestion cases were available primarily for marine mammals and were lacking entirely for seabirds in the region. The regional expert elicitation led to entanglement and ingestion cases from SE Asian countries being documented in 10 and 15 additional species respectively, highlighting the utility of a broader approach to data synthesis. While the scale of the plastic pollution in SE Asia is of particular concern for marine ecosystems, knowledge of its interactions and impacts on marine megafauna lags behind other areas of the world, even after the inclusion of a regional expert elicitation. Additional funding to help collate baseline data are critically needed to inform policy and solutions towards limiting the interactions of marine megafauna and plastic pollution in SE Asia.
东南亚是一个生物多样性高度丰富的地区，但据估计，该地区累计造成了全球海洋塑料污染总量的三分之一。众所周知，这种威胁对海洋大型动物有不利影响，然而，最近人们强调，了解其影响是该地区研究的一个优先事项。为了填补这一知识空白，我们对东南亚现存的软骨鱼类、海洋哺乳动物、海洋爬行动物和海鸟物种进行了结构化文献综述，整理全球范围内的案例以便进行比较，同时进行了一次区域专家意见征集，以收集在结构化文献综述过程中可能被遗漏的其他已发表和灰色文献案例。在东南亚存在且在其他地方也有研究的380种海洋大型动物物种中，我们发现，记录塑料缠绕（n = 55）和塑料摄入（n = 291）的所有出版物中，分别有9.1%和4.5%是在东南亚国家进行的。在物种层面，东南亚国家已发表的缠绕案例仅涉及每个分类组中10%或更少的物种。此外，已发表的摄入案例主要是关于海洋哺乳动物的，该地区的海鸟则完全没有相关案例。区域专家意见征集分别又记录了东南亚国家另外10种和15种动物的缠绕和摄入案例，突出了采用更广泛的数据综合方法的实用性。尽管东南亚塑料污染的规模对海洋生态系统尤为令人担忧，但即便纳入了区域专家意见征集，关于其与海洋大型动物的相互作用及影响的知识仍落后于世界其他地区。迫切需要额外资金来协助整理基线数据，以便为制定政策和解决方案提供信息，从而限制东南亚海洋大型动物与塑料污染之间的相互作用。
