Wholphin behavior represents both parent species. They are intelligent, highly social, and can be trained to do complex tasks; shared traits of false killer whales and bottlenose dolphins alike. Captive wholphins have been observed to be playful and show a great deal of curiosity about their surroundings, the same as bottlenose dolphins.
In the 1980s and 1990s, several attempts were made to capture dolphins and relocate them to a reserve. A breeding program would then allow the species to recover and be reintroduced to the Yangtze after conditions improve. However, capturing the rare, quick dolphins proved to be difficult, and few captives survived more than a few months. [2]
Many animal species have specific mating (or breeding) periods e.g. (seasonal breeding) so that offspring are born or hatch at an optimal time. In marine species with limited mobility and external fertilisation like corals , sea urchins and clams , the timing of the common spawning is the only externally visible form of sexual behaviour.
