The idea of The Numbers Game is to enter a number into the search bar of your computer and then post a selection of the photos that turn up. This week’s number is 222. Captions are on the photos. You can see more responses here.

I saw this this Spotted Pufferfish on a recent swim and was lucky to capture it giving me the eye before it turned away.
I know this fish as a Crocodile Needlefish (Tylosurus crocodilus), a name explained by looking at the jaws and teeth. Elsewhere, it’s known as a Houndfish. When I first saw it, I thought it might have a bit of fishing gear hooked into its mouth. It was working its jaws up and down, as if it might be trying to dislodge something. But when I got closer, I saw it had a fish in it’s mouth.
The unlucky fish looks like a toby, probably an Hawaiian White-spotted Toby. Except the unlucky fish might be the needlefish because the toby has clearly inflated itself, as they do. Not only that, but the skin of these tobies is highly toxic. My fish book tells of a diver who found a frogfish with one of these tobies inflated in its mouth. The frogfish was dead, though whether suffocated or poisoned he couldn’t tell. He freed the toby, which swam away none the worse for wear!
I posted a photo of a Spotted Pufferfish a while back (here). That one was brown. This one’s black, but both have similar white spots.
On a recent swim I saw this Spotted Pufferfish milling about high in the water. Usually they disappear fairly quickly when approached, but this one didn’t and I was able to get this photo, with the fish’s spots illuminated by the sunlight.
This Spotted Pufferfish was in the open when I first saw it, but it quickly disappeared under a ledge before I got a photo. I waited though, and sure enough, it couldn’t resist a peek to see if I’d gone.
This Reef Lizardfish snagged itself a prospective lunch. The trouble is, its lunch is a Whitespotted Toby and, like all pufferfish, one mode of defense is to inflate itself so it can’t be swallowed. This toby has done just that and the lizardfish will have a hard job getting that down.
If it is successful, it might still be in trouble since another of the toby’s defenses is a skin toxin which renders it, at best unpalatable, and at worst, deadly!
The Hawaiian Whitespotted Toby is a small pufferfish that’s endemic to Hawaii. Like many small fish, and juveniles of larger fish, they will use the quills of sea urchins to shelter from predators. Not that tobies need too much help. When attacked they inflate themselves like a balloon, making them hard to swallow. In addition, this toby secretes a nasty skin toxin which will deter most predators.
