In the animal world, we consider fish quite remote to that of humans. We have some deeply ingrained misconceptions about fish, like the one about their memory not spanning more than a few seconds or the one about their inability to feel any pain. Yet, they are similar to humans in several ways.
- Fish don’t have three-second memories but can remember other fish for 24 hours.
- In a 2003 study, fish displayed classic pain responses that ended when they were given painkillers.
- Tests show that zebrafish not only can become impatient but respond to medication to combat impatience.
