Often, invertebrates from our coast require temperates in the 50’s and 60’s (Fahrenheit) and do not do well at tropical temperatures. Famously, the black turban snail (
Tegula funebralis) that gets misidentified as the margarita snail (
Margarites pupillus) has an upper temperature limit of 64 °F and is notorious for its short lifespan in reef aquaria. The blueband hermit crab (
Pagurus samuelis) which is very common in California tide pools is “twice as likely to survive at 20℃ than at 30℃, and at 5℃ than at 30℃.” The mussels would also require
frequent phytoplankton dosing to stay alive since they are not photosynthetic.
While tide pool organisms might be able to temporarily withstand these “max” warmer temperatures (ex. due to seasonal changes and sun exposure), I doubt they would last very long under these conditions long-term.
