This is your periodic reminder to stop feeding, petting, grabbing, and otherwise harassing the wildlife. In addition to the danger you put yourself and other people in, when you habituate a wild animal to human food or contact you set them up for disaster. A fed animal is a dead animal.
Pretty much this. This situation happened because the sea lion was habituated to people and brave enough to start looking for food to steal (my best guess is the edge of the kid’s dress looked like the paper wrapping on a sandwich). Don’t fuck with the wildlife, because it fucks up the life of the wildlife.
Observe and do not engage, look and do not touch.
