摘要：

1. All three oyster species have an upper lethal temperature (24 h) of 40-42-degrees-C. 2. Saccostrea cucullata may be exposed to 43-degrees-C for short periods when emersed under strong sunlight. 3. The mean lower lethal temperatures (24 h) for S. cucullata, Crassostrea belcheri and C. iradelei were 4.8, 5.0 and 1.4-degrees-C respectively. 4. All three species respond to emersion by tight shell valve closure. The rock oyster Saccostrea cannot "afford" to take up oxygen from air because of the risk of desiccation.
