“…Camouflage is key for animals to survive in different color backgrounds (Johansson & Nilsson‐Örtman, 2013; Manríquez et al, 2008; Merilaita & Stevens, 2011). Because the visual background is the main basis of camouflage, it is crucial for various species to adapt their body coloration to the surrounding substrate, including fish (Kelley et al, 2017; Kjernsmo & Merilaita, 2012), amphibians (Polo‐Cavia et al, 2016; Rabbani et al, 2015), reptiles (Hamilton et al, 2008; Kravchuk & Watson, 2020; Krohn & Rosenblum, 2016; Marshall et al, 2016; Merilaita & Lind, 2005), birds (Lovell et al, 2013), and insects (Batty, 2008; Kang et al, 2015). The camouflage strategy not only benefits the prey by defending it against predators, but also helps predators capture the prey more efficiently (Cadena et al, 2017; Cook et al, 2012; Edelaar et al, 2017).…”
