Attina
Attina is the oldest daughter of King Triton and Queen Athena in The Little Mermaid Franchise. Her first appearance is tn the first film. In that movie, she makes 3 cameos, one in Daughters of Triton and another in the secne where Ariel hums Part of Your World in front of her father and sisters and finally during Ariel and Prince Eric's marriage at the end of the movie. She rarely appears in the TV Series and only once in The Little Mermaid 2 : Return to the Sea  when Ariel names her daughter, Melody. In fact, her largest appearance is in The Little Mermaid 3 :Ariel's Beginning when her father bans music from Atlantica after her mother's death, she joins Ariel and her other sisters in Sebastian's secret concert and when music is allowed back into Atlantica, celebrating Sebastian's appointment as court composer and the return of music!

Aquata
Aquata is the second daughter of King Triton's royal family which makes her younger than Attina, but older than the other 5. She comes into the spotlight for the first time in The Little Mermaid duirng Daughters Of Triton. Later in the movie, she, along with 3 of her sisters and father suspect Ariel's lovesick behavior and in the climax, she joins them, happily waving goodbye to her when she marries Prince Eric. She makes very few appearances in The TV Series, and only 1 when Ariel celebrates her daughter, Melody's birth in The Little Mermaid 2. However, she does appear many times in the third film which shows her mother's death, causing her father to ban music in Atlantica. For example, she and her other sisters go to Sebastian's forbidden concert and later after thetr father lifts the ban after 10 years and celebrates with everyone except Marina Del Rey. Aquata is the most obsession-compulsive of her sisters; when Arista borrowed her things, including her hairbrush, her "lucky" seashells, her pillow, and her stuffed seahorse, Mr. Fuzzifinkle, she displayed frustration and some hostility, and an impulse to get her things back immediately. She was initially very self-conscious and shy, as seen in "Ariel's Beginning" when 3 club-goers asked her for a dance, which she immediately declined. She admitted she can't dance, is "a mermaid with no grace," and resembling, "a spastic piece of kelp." Upon hearing this, her sisters,Alana and Andrina put her in the spotlight dance to help her loosen up. She quickly does so, and dances awkwardly and out-of-step. Nevertheless, her dances are met with praise and approval from her sisters. And her inhibitions gone, she starts a conga line at the Re-instation of Music Celebration in Atlantica.

Andrina
Andrina is the third-born daughter in King Triton's family which makes her age between that of Arista and Aquata. Andrina makes her way onto the spotlight in the fist film during the song, Daughters of Triton. When Ariel sings to herself later in the movie, Andrina is the first sister to spot her lovesick attitude. At the movie's climax, Andrina watches happily as Ariel and Eric get married. Andrina's appearances in  the TV Series are unknown for the time being. However, she does appear when Ariel has her fist born child in the sequel.. Her major appearance is in the third film. When King Triton bans music due to his wife's demise, the 7 of them are upset. In fact, 10 years later, Andrina and the 5 other sisters willingly join Ariel in watching Her first appearance, like her other sisters is in the first film has 3 cameos, Daughters of Triton, the scene where Andrina tells thier father that  Ariel is in love and when they wave goodbye to her at the end of the movie when she marries Prince Eric.

After the defeat of Marina Del Rey, Adella celebrated with her father, sisters and her fathers whole court while Marina was thrown in jail for her crimes against Atlantica. Andrina appears to be the one with the largest sense of humor, as seen by her many jokes in the prequel

Arista
Arista is the 4th oldest daughter of King Triton and Queen Athena. Her magical debut was in the beginning of the first film during 2 scenes. The first was Daughters of Triton, the second and final one was when she saw the marriage of Ariel and Prince Eric and waved goodbye to her. In the TV Series, she was always jealous of Ariel's adventurous ways and therefore, followed her on some of her travels. In the second film, she appears watching Ariel's new born daughter 's birth ceremony. Her biggest role takes place in the third film. In that movie music is forbidden in Altanica because of Queen Athena's death until Ariel shows King Triton  how wonderful music can be. At the end of the movie, everyone except Marina celebrates the return of music! She also helps Ariel stop 2 gators from robbing the Royal Treasury, when she and her youngest sister are beached (or grounded, as the case is.) Based on the prequel film, "Ariel's Beginning," Arista is the most energetic one, though she does lose this in her later years, adopting a more by-the-rules personality, as seen in the TV episodes, "Against the Tide," and "Beached." Although, in the latter of the two, a small bit of her energetic side surfaces again to help Ariel stop the thieving gators from robbing the palace.

Adella
Adella is the 5th daughter of the royal family and is therefore two years older than Ariel. Her first appearance, like her other sisters is in the first film with 3 cameos, Daughters of Triton, the scene where Andrina tells thier father that Ariel is in love and when they wave goodbye to her at the end of the movie when she marries Prince Eric. In the TV series, she is pranked by Urchin and later gives Triton a Father's Day gift which turns out ot be the same thing every year. Her longest appearance is in the third film which shows the past of the 7 sisters. After Triton bans music as a result of what happened to his late wife, she, along with her sisters are raised with strict rules for the next 10 years. A decade later, Ariel gives her father a change of heart with the music box that their deceased mother owned and treasured while she was still alive. After the defeat of Marina Del Rey, Adella celebrated with her father, sisters and her fathers whole court while Marina was thrown in jail for her crimes against Atlantica. Adella has also gone through a transformation in her life; in her early years, she was shapely and thin. After her father reinstated music, she gained a little weight, as seen in the TV series. However, after her youngest sister, Ariel, left the sea to be with her husband, Eric, she was seen at her niece's Christening back to her slender old self, happily celebrating. And, based on the prequel film, Adella is the most boy-crazy.

Alana
Alana is the next-to-youngest princess of Atlantica, as said in the TV episode, "Eel-Ectric City." She first appeared in the first film where she made cameos in Daughters of Triton and the marriage scene of Ariel and Prince Eric. She also appears in the TV Series  going on one of Ariel's misadventures where the 2 of them needed to be rescued by thier father and were beached (grounded in the Little Mermaid world) as punishment. She also appeared briefly in  the second film, watching the birth of Melody. Her main appearance was in the third film, where her father forbade music in Atlantica until Ariel showed him the error of his ways by letting him listen to thier mother's music box after she was killed by priates not long before the 10-year music ban which was lifted soon afterwards. Alana was last seen celebrating Marine Del Rey's defeat and the return of music. Alana appears to be the one who is most interested in beauty & health. This can be seen in "Ariel's Beginning," where she mostly talks about her looks, but she is, by no means, selfish or vain. This is proven where she, and her younger sister, knowing when they've reached their limit on peer-pressure, stop partying with their teenage friends in the tV episode, "Eel-Ectric City."
