The respiratory behaviour of Murex pomum was measured after 24 hr exposures to single factor changes in temp and salinity.
2.
2. The thermal limits for the population are about 11 and 33°C.
3.
3. The determined salinity boundaries for the population are about 11 and 49%.
4.
4. The tolerance potential of M. pomum to both temp and salinity greatly exceeds normal habitat requirements.
5.
5. The salinity tolerance potential M. pomum may be indicative of historical and phylogenetic relations and provides the base for further speciation
