Hawaiian monk seals face many threats caused by humans, including food limitation and habitat loss. However, one of their most significant threats is marine debris. Hawaiian monk seals are observed stuck in nets and fishing gear more than almost any other pinniped (seal, sea lion, or walrus) species. Seals can be entangled in all types of derelict fishing gear, including nets, lines, and hooks from non-commercial and commercial fishing. Entanglement can make it difficult for seals to breathe, hunt for food, and escape from predators, potentially leading to injury or death. Entanglement is seen more frequently in Papahānaumokuākea Marine National Monument.
