What coloration do yabbies typically exhibit in turbid or muddy waters?
Answer
Light brown, green-brown, or beige
The pigmentation of the common yabby demonstrates remarkable plasticity, adapting directly to the substrate and water clarity of its habitat. When inhabiting environments characterized by turbid conditions, such as muddy farm dams, the crayfish shifts its coloration to lighter tones to achieve camouflage. These resulting hues often manifest as light brown, green-brown, or beige, contrasting sharply with the darker shades observed in clearer waters. This ability to match the surrounding environment provides a significant evolutionary advantage against visual predators like water birds.
