Two new gastropod holobionts from Atlantic hydrothermal vents showing different levels of endosymbiosis dependence
Chemosynthetic symbioses underpin animal life at deep-sea hydrothermal vents, encompassing substantial variabilities in symbiont identity, metabolic capacity, and host dependence. Here, we characterise symbioses in two peltospirid snails from Mid-Atlantic Ridge vents, Peltospira gargantua and P. smaragdina, using 3D an...
