I was at South Padre Island and the beach I was at is kinda a private area for people staying at beach houses, so there was a lot of crabs and what not running around. Well I was walking along the shore and I was a plant 'jumping' I looked at it closer and it was a fish! I have looked around websites trying to find out what kind of fish it was, does anyone here know? I was about 4 inches long, and it looked just like the plant material that washes up on the beach.
