After being in with the meerkats they went to see the dolphins it turned out be Tina’s favorite animal so she told them all about them .  Dolphins are social, living in pods (also called "schools") of up to a dozen individuals. In places with a high abundance of food, pods can join temporarily, forming an aggregation called a superpod; such groupings may exceed a thousand dolphins. The individuals communicate using a variety of clicks, whistles and other vocalizations. They also use ultrasonic sounds for echolocation. Membership in pods is not rigid; interchange is common. However, the cetaceans can establish strong bonds between each other. This leads to them staying with injured or ill individuals, even actively helping them to breathe by bringing them to the surface if needed.^[15] This altruistic behavior does not appear to be limited to their own species however. A dolphin in New Zealand that goes by the name of Moko has been observed to seemingly help guide a female Pygmy Sperm Whale together with her calf out of shallow water where they had stranded several times.^[16] They have also been known to seemingly protect swimmers from sharks by swimming circles around them.^[17][18] Dolphins also show cultural behavior, something long believed to be a quality unique to humans. In May 2005, a discovery was made in Australia which shows this cultural aspect of dolphin behavior: Some dolphins, such as the Indo-Pacific Bottlenose Dolphin (Tursiops aduncus) teach their young to use tools. The dolphins break sponges off and cover their snouts with them thus protecting their snouts while foraging. This knowledge of how to use a tool is mostly transferred from mothers to daughters, unlike simian primates, where the knowledge is generally passed on to both sexes. The technology to use sponges as mouth protection is not genetically inherited but a taught behavior.^[19] Another such behavior was discovered amongst river dolphins in Brazil, where some male dolphins apparently use objects such as weeds and sticks as part of a sexual display.^[20] Dolphins are known to engage in acts of aggression towards each other. The older a male dolphin is, the more likely his body is covered with scars ranging in depth from teeth marks made by other dolphins. It is suggested that male dolphins engage in such acts of aggression for the same reasons as humans: disputes between companions or even competition for other females. Acts of aggression can become so intense that targeted dolphins are known to go into exile, leaving their communities as a result of losing a fight with other dolphins. Male Bottlenose Dolphins have been known to engage in infanticide. Dolphins have also been known to kill porpoises for reasons which are not fully understood, as porpoises generally do not share the same fish diet as dolphins and are therefore not competitors for food supplies   Tina how do know  all that stuff about dolphins. asked Bette    In college I was studying to be a dolphin trainer cool said Alex  Bette looked at he watch and realized that it was time for lunch so they went into  a place  the saloon and had lunch  Alex got Burger’s and fries, Bette got chicken fingers Tina got a slice of  pizza   Mom can I get a Big gulp asked Alex    no that’s way too much you can have a small. Alex pouted but told the waitress anyway Bette had  some apple juice in her bag. Alex was busy eating, chatting about how cool everything was. Tina and Bette were a little nervous  Tina didn’t want to hover and stare. Bette  felt like she would be under a microscope this was the first meal  since her telling Tina.   Bette pushed her food around on her  plate Tina  kept glancing over while eating to see  how much Bette had eaten. It was a very awkward  Bette did eat ony half of the food. She  slid next to  Tina  T  I am going to  sit on the bench outside   Come out when your ready   Bette sat down thinking about how she felt when  looking at the food, pushing it around on her plate.  Lunch went bad in part because when she looked at food in that moment it looked disgusting the most unattractive ting she could think of and that made her want it even less. She also had placed pressure on her self to eat because she want to show Tina she was ok. But lunch just proved how far away she really was.  Alex and Tina came out a bout 15 minutes later.
