Ocean temperature significantly influences marine biodiversity by affecting the distribution and behavior of marine species. Higher temperatures can lead to coral bleaching, disrupting habitats for numerous organisms, while also causing shifts in species ranges as marine life seeks more suitable conditions. Altered temperatures impact reproductive cycles, migration patterns, and interspecies interactions. Changes in marine biodiversity can reverberate through entire ecosystems, highlighting the need for understanding these dynamics in the context of climate change and conservation efforts to protect marine environments.
