Fig. 3

Decapod species with fossilized WSSV-like viruses (marked red), with WSSV-like sequences in ESTs libraries (yellow) or with evidence of absence of WSSV-like sequences in genomes (green). The cladogram to the left is a simplification of the phylogenetic relationships between the species considered based on (Tsang et al. 2008; Ma et al. 2011; Tsang et al. 2014), all other decapod groups are omitted. The numbers of WSSV-like ESTs discovered in our BLAST analysis are provided in parentheses
