Invertebrates like insects typically have the lowest levels of testosterone among animals. Unlike mammals, their hormonal systems are fundamentally different, resulting in minimal to negligible testosterone activity.

FAQs & Answers

  1. What is testosterone? Testosterone is a hormone that plays key roles in the development of male sexual characteristics, but its levels vary widely among different animal species.
  2. How do invertebrates differ from mammals in terms of hormones? Invertebrates have fundamentally different hormonal systems compared to mammals, resulting in significantly lower testosterone activity.
  3. Are there any vertebrates with low testosterone? Yes, some vertebrates have low testosterone levels, but invertebrates typically have the lowest overall hormonal activity.
  4. What role does testosterone play in animals? Testosterone influences various biological functions, including reproduction, muscle growth, and behavior in many animal species.
