So I asked leading shark ethologist and behaviourist, Professor Samuel 'doc' Gruber to elaborate. After pointing out how much pain women feel when they give birth, making the point that suffering has no effect on reproduction, he reminded me that sharks evolved their mating behaviours and the physical structures involved, separately from other animals.
Now, additional findings lends further credence to the notion that fish do indeed possess emotions and harbour thought processes. It turns out that fish growing up in the wild among predators use their left eye to look at novel objects, while their offspring raised in captivity use the right eye.
Researchers have discovered that differences in the patterned clicks of sperm whale communication may lean towards culture rather than genetics. A study published in Behaviour Genetics suggests that sperm whale groups are made up of individuals that use the same dialect, rather than those that come from a similar area of the Pacific.
