As we know, dolphins are very social animals that are organized in pods and maintain physical contact, especially in reproduction periods where scientists have discovered that sometime there are up to ten males for each female, making it a strong competition. Although known as friendly and peaceful, we should not forget their wild condition, because when it comes to winning the acceptance of female dolphins, they can show aggressive attitudes and even perform chases and fights. Although these are not usually very violent or deadly, they may result in some injuries.
