But there's also a lot of visual roles, and visual roles can be aimed at predators.
They're often aimed at predators.
And these include things like camouflage.
So we have some shells like the emerald nerite that's a beautiful green and matches the seagrass it lives on.
You also have some where they're actually trying to warn off predators.
There are no good reports of studies where they've shown this in shells, but cone shells are very venomous and they have very vivid markings.
So it's possible that those are acting as a warning.
The shells themselves in this case.
So it's possible that that's warning octopus and fish and other things to stay away.
You also have things that mimic other things.
So there are some shells that look like the hydroids they're sitting on.
There's a limpet in the intertidal region where a lichen eats away the top of the shell down through the first shell layers, reveals some colour underneath and makes it look like the open mouth of a barnacle.
And the limpet lives next to barnacles.
And it's a really good hiding spot because the predators don't like removing the barnacles.
They're hard work to get off, whereas the limpets are easy.
So by pretending to be a barnacle, they're avoiding being eaten.
But their colours themselves are much less likely to be used for intraspecific signalling.
Yeah, so there's amazing examples of cephalopods.
There's a lovely video of a squid that has put different colours on both sides of its mantle, split right down the middle.
It's showing an attractive colour to a female on one side and a go-away colour to a competing male on the other side.
