Peanut head
Scarlet's thin form means there's a dip at the base of her skull, where she's lost fat. Experts call this "peanut head," and it's not a good sign.
Small girl
Scarlet is small for her age, but in the past month she's looked particularly emaciated.
J Pod
Scarlet is part of the J pod, one of three small groups of orcas within the endangered Southern Resident Killer Whale subpopulation.
Family ties
Scarlet's mom and sibling are also part of the J pod.
