Fish tails are something that we see everyday. And different species use their tails in very different ways to travel around the reef.
But today, I encountered the above smooth trunkfish with no tail, swimming almost as well without a tail as its species-mates who had tails. If the tail had been bitten off, the bite has long since healed. So, not every fish needs a tail to survive.
Below are a couple of photos of smooth trunkfish with tails. They are triangularly shaped boxfish, about 6 inches long.
