David White, the owner of the Solar Whisper Daintree River Wildlife Cruises, filmed something unexpected at the mouth of the Daintree River in far North Queensland on August 8.“Looking for a crocodile at low tide in a mud puddle, found this instead, is it a mini whale, a fish or a mussel?” he said.White wasn’t sure. Other guesses on his company’s Facebook page included a lungfish, “your own Daintree monster, like Nessie!” and an underwater monster.
