The Hawaiian bobtail squid, Euprymna scolopes, has a clever way of duping predators during its nightly activities. Scientists have discovered that the squid uses a symbiotic luminescent bacteria to light up its underside, so that upwards-looking predators don’t see a dark, edible form silhouetted against a moonlit or starlit sky. Instead, hungry sharks or other fish see only sky | image by Mattias Ormestad
