There is a sieve moray eel that lives in a hollow in an old wharf pile under the wharf at Chowder Bay, Sydney Harbour. Bill always visits her when he dives there. She’s usually alone, but sometimes shares the hollow with a green moray eel.
“These two moray eels often share the same hole: the sieve moray on the left and the green moray on the right. It’s cramped but they look comfortable and relaxed with one another. It’s unusual for fishes of different species to hang-out together like these two are doing, especially two moray eels that probably compete for the same food.”
”Perhaps they understand that ‘four eyes are better than two’ when it comes to noticing predators, and each eel’s chances of survival are improved if it can live with another, even when the other is a different species.”
