Magela hardyhead

The Magela hardyhead or Mariana's Hardyhead (Craterocephalus marianae) is a species of fish in the family Atherinidae endemic to Australia.[2] It has a very restricted distribution, only found in the Alligator Rivers region of the Northern Territory where it inhabits shallow and fast-flowing freshwater creeks.[3] The fish has a high thermal tolerance, like some other species in the genus Craterocephalus, and may tolerate water temperatures up to 39.5ยบ.[3] The specific name honours Walter Ivantsoff's daughter, Marian.[4]
