Spike Pufferfish

IMG_0167 copy 2

Here’s one that I haven’t seen before. My last night dive was so much fun I couldn’t wait to do it again. This pufferfish has been a unique find. I now know there are three kinds – pufferfish, masked, and spiked. This one looks the most unusual, almost bizarre and cartoonish. I imagine the spikes to be like thorns on a tree. And then I wonder why nature evolved this way.

Wrong! Reading helps. This is a porcupine fish also called blowfish but apparently are related to but are not pufferfish. It turns out that the spike erect as the fish blows up. So far I have only seen this fish with its spikes up. As a puffer or blow fish, I had imagined them inflated like a balloon with its spikes out on all sides. Wrong again, I guess.IMG_1959
