COFFINFISH

The coffinfish sucks in water when it feels threatened and blows itself up like a balloon. This makes it appear bigger so predators might leave it alone ( pufferfish use the same tactic). Similar fish have been found elsewhere in the deep sea, including Indonesia, Japan and Hawaii. But this is a first sighting for Australia. Bray explains that she’ll need to X-ray it and possibly sequence its DNA to find out whether it’s the same species. “It would be really cool if it’s actually new,” she says.
