Limits RegistryThe Arabian oryx (Oryx leucoryx) and camel (Camelus dromedarius) can allow their core body temperature to rise to around 41-42°C during the heat of the day as a water-conserving adaptive heterothermy strategy, later dumping the stored heat at night — among the highest voluntarily tolerated core temperatures documented in a mammal without tissue damage.
The question, scope, and sources behind this Registry record.
The Arabian oryx (Oryx leucoryx) and camel (Camelus dromedarius) can allow their core body temperature to rise to around 41-42°C during the heat of the day as a water-conserving adaptive heterothermy strategy, later dumping the stored heat at night — among the highest voluntarily tolerated core temperatures documented in a mammal without tissue damage.
The highest core body temperature a desert-adapted mammal is documented to tolerate through adaptive heterothermy without heat injury, as measured by implanted temperature loggers in field studies.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
