J47 Notch is the first child of Tahlequah (J-35) and was born in 2010. When he was young he was wounded and now has a large notch in his dorsal fin (which is where he got his name). Tahlequah gave birth to another orca in September of 2020 whose name is Phoenix (J-57). Notch has an Uncle Moby (J-44) and cousin Star (J-46) and is close with them because they were all born around the same time. In 2018, his mother gave birth to his sister who only lived for one hour which led to a long grieving time for these whales.
