Dataset to the article "An exploration of the hidden endosymbionts of Corbicula in the native range"

This dataset contains a description of materials and metods, as well as figures and table for the article entitled " An exploration of the hidden endosymbionts of <em>Corbicula </em>in the native range", which is accepted for publication in <em>Ecology</em> (The Scientific Naturalist). In this paper, we report on the discovery of multiple endosymbionts of the mantle cavity and soft organs of <em>Corbicula</em> clams from Laos and Thailand. <br> The dataset's files are as follows: (1) <em>Figure 1.TIF</em>: Figure 1. <em>Corbicula </em>clams and their endosymbionts: (a) Morphology of <em>Corbicula leana</em> from irrigation channel near Mangyeong River, South Korea, 35.9143N 126.7077E, 11 July 2018; (b, c) Embryos of gudgeon <em>Sarcocheilichthys soldatovi</em> from the mantle cavity of<em> C. leana</em>, irrigation channel near Mangyeong River, South Korea, 35.9143N 126.7077E, 11 July 2018; (d) Larva of <em>Symbiocloeon </em>sp.
