What are the characteristic features of the Cherax destructor rostrum between the eyes?
Answer
Short, broad, and spineless
The external anatomy of the yabby features several defining characteristics used in distinguishing species, particularly concerning the cephalothorax region. The carapace, which covers the internal organs, is generally smooth in texture. A key distinguishing feature is the rostrum, which is the forward-projecting structure located between the eyes. Unlike some other crustacean species that possess elongated or sharply pointed rostrums, the rostrum of the *Cherax destructor* is specifically described as being short, broad in its base, and notably lacking spines. This distinctive, relatively blunt shape on the leading edge of the cephalic shield contributes to its unique external profile.
