Local Distribution and Habitats

Thuridilla bayeri are found associated with coral substrates. They can be found clawing on the the substrate and algae. However no evidence recorded to support the association of T. bayeri with any alga in particular. The specie is common in low intertidal zone up to 18 metres. They are very common during the low tide. During the sampling period, more than 10 T. bayeri were found within an hour snorkeling period each day. Australia T. bayeri can only be found in Great Barrier Reef, Queensland, and Western Australia (Marshall 1999; EOL 2011). 


  According to EOL (2011), table below show optimal the water temperature and chemistry condition suitable for T. bayeri.

The data clearly show the environmental ranges suitable for T. bayeri. The maximum temperature that they can survived is 28.496 °C. Average surface water temperature of the ocean is 29.546°C (EOL,2011). Climate change is one of the big problem raising ocean temperature, therefore, it is possible that T.bayeri in some area may not be able to survived in the future e.g. T.bayeri in the country near the equation e.g. Thailand.
