Juvenile Australian Fresh Water Crocodiles.
Unlike the monstrously large (and literally monstrous) "Salties" Salt Water Crocodiles these young "freshies" are almost cute...
they mostly eat fish and are relatively sedate around humans.
At this age they can still be handled reasonably safely though once fully grown (about 2 meters) they are definitely not so "cute" and cause very painful though not directly life threatening bites if handled roughly and agitated
