Decapod iridescent virus 1 (DIV1), the first isolated species of the genus Decapodiridovirus (family Iridoviridae), is a major pathogen threatening farmed decapods, causing large-scale disease outbreaks and high mortality. However, the mechanisms underlying its cellular entry remain poorly understood. In this study, we investigated DIV1 internalization using hematopoietic tissue cells of Cherax quadricarinatus. Pharmacological inhibition assays showed that (i) clathrin-depen
