Figure 2From: Expression pattern of three-finger toxin and phospholipase A2 genes in the venom glands of two sea snakes, Lapemis curtus and Acalyptophis peronii: comparison of evolution of these toxins in land snakes, sea kraits and sea snakesPairwise intraspecific (white bar) and interspecific (black bar) distances for land snakes, sea snakes and sea kraits. Panel A: 3FTx (1a and 1b: land snakes; Pseudonaja textilis and Bungarus species respectively), 2 and 3: sea kraits and sea snakes respectively. Panel B: PLA2: (4a and 4b: land snakes; Australian elapids and Bungarus species respectively), 5 and 6: sea kraits and sea snakes respectively. RF denotes relative frequency.Back to article page
