Pretty boy – Enneapterygius atrogulare – Black-throat triplefin #marineexplorer #underwatersydney by John Turnbull

Many animal species are sexually dimorphic – ie the male and female look different. This is the male black throat triplefin, resplendent with black head and orange body. I suppose it means “aren’t I impressive, come mate with me” – but it also could mean “come eat me” to predators! The female is less showy (but also less likely to be a meal, perhaps), see: flic.kr/p/2idwsqB

When you’re as flexible as an octopus you can make sure your eyes are always up – irrespective of whether your head is above or below them. I wonder if the octopus’ brain sees upside-down or corrects accordingly? Here’s an image of an octopus “right side up” if there is such a thing: flic.kr/p/2idzV8c . Camp Cove

We normally see wobbys sheltering under ledges and in caves during the day. Every now and then you find one in a peculiar place, like this one hunkered down in the sand in 8 m of water at Shelly Beach, Manly.

What a way to end 2019 – over 2 hrs underwater at Clifton Gardens with a dozen or so seahorses, half a dozen morays and octopus, and plenty of other critters.

This nudibranch is unusual in that it mimics both the colour and shape of the host sponge on which it lives. There are three animals in this shot at Bare Island
