Influence of water temperature on the larval development of Neoverruca sp. and Ashinkailepas seepiophila-Implications for larval dispersal and settlement in the vent and seep environments

► We study larval development of barnacles from vent and seeps at two temperatures. ► Ashinkailepas seepiophila completed the development in 65 days at 4 °C, shorter than Neoverruca sp. in 100 days. ► Opposed to Neoverruca, A. seepiophila did not respond dramatically to thermal stimulation. ► Barnacles that live in active seeps and inactive vents showed weak thermal response in larval development.
