Marine Mammals Apr 21, 2021 Marine Mammals Do not go near any marine mammal that is beached. It is against the law to disturb them or touch them. If you think a marine mammal may be injured or sick, call a wildlife center. Mother seals will leave their babies on the beach all day, so it is normal to see them alone. Do not touch the baby seal. Keep pets and children away. If you find a dead marine mammal, call a wildlife center to get information on how to legally dispose of it. A local marine mammal group may want information on the dead marine mammal, so please call your local wildlife center.
