Which of the Following is NOT True About Crayfish Dominance

Question

Which of the following is NOT true about crayfish dominance hierarchies?
A) Higher-ranking individuals have greater access to food.
B) Aggression levels are lower after the hierarchy is established.
C) Protandry determines ranking within the hierarchy.
D) Hierarchies form in the absence of food.
E) Aggression is high before hierarchy formation.

Accepted Answer

Protandry, which refers to organisms changing sex from male to female during their life cycle, does not determine ranking within crayfish dominance hierarchies. Crayfish hierarchies are typically established through direct physical confrontations and displays of aggression, not through protandric processes.
