Evolutionary tree for Israeli Aequorea macrodactyla by mtDNA 16S marker compared with other members of Aequorea. Molecular phylogenetic analysis by Maximum Likelihood Method, an evolutionary tree based on partial sequences of 354 base pairs (bp) mitochondrial DNA (mtDNA) marker 16S. The black triangle represents the local A. macrodactyla jellyfish of the Mediterranean according to the DNA molecular sequence acquired in this work. The outgroup for this tree is represented by Hydra polymorphus and H. vulgaris. The test of phylogeny is by Bootstrap method and the number of bootstrap replications is 1000. For the taxon name we used the NCBI GenBank reference number.
