About 45-60 centimeters (18-24 inches).
I noticed this guitarfish in about 20 ft of water as we were swimming back from our dive at Monastery. Brenna had air, so she went down for a closer look, and took a sweet picture.
There were hundreds of them and they let you get within a few feet of them. Too bad the rest of the day was a wreck.
Wow, there are a lot of things named "thornback." This one was a kind of guitarfish, which is a kind of bottom-dwelling shark relative. Nate found this on our first dive. About 1 m long.
The guitarfish are a family, Rhinobatidae, of rays. The guitarfish are known for an elongated body with a flattened head and trunk and small ray like wings. The combined range of the various species is tropical, subtropical and temperate waters worldwide. They often travel in large schools.
