Topshell Tectus pyramis is a coral reef snail of economic and ecological value. This study assessed temperature and salinity tolerance in T. pyramis and the interaction between temperature and salinity on metabolism. The adaptability of T. pyramis was assessed with mortality, respiration, and nitrogen excretion. This study found that snail (T. pyramis) with body sizes of width 60.30 ± 3.46, 40.12 ± 2.34, and 20.02 ± 1.15 mm tolerated temperatures of 15–35, 15–35, and 20–30°C and salinity of 13–38, 18–38, and 23–33‰, respectively. It demonstrates that larger snails can adapt better to variations in temperature and salinity. Temperature and salinity have a significant effect on the metabolism of snails. Smaller snails have a higher metabolism and are more sensitive to changes in temperature and salinity. Overall, results suggest that seawater with 30°C temperature and 33‰ salinity was suitable for T. pyramis.

珊瑚礁顶壳 Tectus pyramis 的温度和盐度适应性

Topshell Tectus pyramis是一种具有经济和生态价值的珊瑚礁蜗牛。本研究评估了四棱锥虫的温度和盐分耐受性以及温度和盐度对新陈代谢的相互作用。T. pyramis的适应性通过死亡率、呼吸和氮排泄来评估。本研究发现蜗牛（T. pyramis) 体型宽度为 60.30 ± 3.46、40.12 ± 2.34 和 20.02 ± 1.15 毫米，耐受温度为 15–35、15–35 和 20–30°C，盐度为 13–38、18–38 和 23–分别为 33‰。这表明较大的蜗牛可以更好地适应温度和盐度的变化。温度和盐度对蜗牛的新陈代谢有显着影响。较小的蜗牛具有更高的新陈代谢，并且对温度和盐度的变化更敏感。总体而言，结果表明温度为 30°C 和盐度为 33‰ 的海水适合于T. pyramis。
