Hooker was born around 1951, most likely to B11. When he was born, his family would have consisted of a grandmother, who is unknown, his older sister Scarlett, and his mom B11. At least, that's to our knowledge.
The next year, Hooker gained a playmate when his grandmother had his uncle Baronet. Baronet and Hooker grew up together and spent lots of time playing and rough-housing.
Within the next 13 years, Hooker got two little brothers, B3 and B5. The four boys had lots of fun together!
In 1964, Scarlett had her first calf, Izumi, giving Hooker ANOTHER playmate!
In 1973, Hooker gained his last brother Bauza, and lost his mom.
Over the next few years...or decades, Hooker got lots of nephews, and a niece. He spent most of his time playing with Baronet, and the other boys as well.
In 1982, 1985, and 1992, Hooker lost his three brothers, B3, B5 and Bauza (respectively).
As his nephews' fins began to sprout, they quickly became new playmates for Hooker and Baronet to have fun with. The rowdy group spent an amazing amount of time playing and socializing.
In 1998, Hooker sadly passed away. The same year, Baronet disappeared as well.
Hooker was a favourite of researchers, first because he was easy to identify, and then because he just seemed to have so much fun. But he could be serious as well, foraging slowly amongst his brothers, or following his mother or sister up north for their little travels.
Hooker was easily identified by his fin, which hooked forward dramatically. Old males often develop a hook in their fin (see Cracroft A36 or Caamano R6, for example) but not normally as dramatic as Hooker's. He also had a noticeable notch midway down his fin.
