Final answer:
The size of the brain in cartilaginous fish does not determine their overall intelligence. Intelligence is a complex trait influenced by various factors.
Step-by-step explanation:
The size of the brain in cartilaginous fish, such as sharks and rays, does not necessarily indicate their level of intelligence when compared to other vertebrates. While their brains are generally smaller than those of other fish, it does not make them less intelligent as a whole. Intelligence is a complex trait that cannot be solely determined by brain size.
For example, some cartilaginous fish have well-developed senses and complex behaviors that demonstrate their adaptability and problem-solving abilities. An example of this is the great white shark, which exhibits strategic hunting techniques and has been observed to solve navigation challenges.
Therefore, it is not accurate to infer that cartilaginous fish are less intelligent than other vertebrates or bony fish based solely on the size of their brains. Intelligence is influenced by various factors, including brain structure, behaviors, and environmental adaptations.
