What temperature can invertebrates handle?

Invertebrates can tolerate a wide range of temperatures, often depending on their habitat and species. For example, some marine invertebrates thrive in cold ocean waters, while others, like certain desert-dwelling insects, can endure extreme heat. Generally, many invertebrates can survive temperatures from just above freezing to over 50°C (122°F), but their metabolic processes and reproductive success are often optimized within narrower temperature ranges. Adaptations, such as antifreeze proteins in polar species or heat shock proteins in thermophiles, help them cope with extreme conditions.
