As I mentioned in my last post, I spent last week on a family vacation near Corpus Christi, Texas. The kids really liked swimming in the ocean, looking for shells, and playing in the sand. I enjoyed all of those things too, but I also spent quite a bit of time wandering the beaches and adjacent dunes with my camera.
Along the beach near our hotel in Corpus Christi, we found several largish intact shells and didn’t immediately realize that all of them hosted hermit crabs. Once we figured that out, we put them back on the beach and watched them crawl back into the water.

It was fun to see what the waves were washing up on the beach. Even the trash – and there was a lot of that – was interesting.

There were others walking the beach too – especially gulls and various shorebirds. I was just looking for interesting objects and photo subjects. The birds were looking for food.
Laughing gulls and other birds were walking the edge of the surf at Padre Island National Seashore, feeding on various small animals washed up on the beach.
As I followed gulls to see what they were eating, much of what they seemed to be feeding on were small terrestrial invertebrates that had apparently gotten caught in the water and washed ashore. Stinkbugs were very abundant, along with a few different beetle species. I saw 20 or 30 stinkbugs washed up in a pretty short stretch of beach.
The starkest reminders that I was far from the prairies of Nebraska were the crabs. Those of you who have followed this blog for a while know about my minor obsession about photographing crab spiders in prairies. I think I could probably develop a similar addiction to photographing crabs. They’re just so otherworldly and fantastic.
Ghost crabs (and other species?) were very common on the beaches at Padre Island National Seashore and San Jose Island. They seemed to spend a lot of time carrying sand out of their holes, and skittered back into those holes quickly as we approached them. This one eventually came back out after I sat quietly next to its burrow.
The crabs along the beaches ranged from very small (this one was about an inch or inch and a half wide – including legs) to maybe 5 or 6 inches wide.

I’m guessing this is a larval crab, but I really don’t know. It was only about 1/2 inch wide and was moving around by squirting water out a tiny jet engine-like appendage coming out its rear end. Padre Island National Seashore.
Tiger beetles were a more familiar sight to me than the crabs. I know tiger beetles, though not the species I was seeing on the beach last week. It turns out beach tiger beetles are just as fun to stalk with a camera as those in prairies. And their faces are just as cute.

Unfortunately, much of what we saw washed up along the beaches was debris from the human race. A huge range of objects, especially plastic ones, were strewn about along the base of the dunes. I tried for a while to compose photos that avoided the trash, but eventually gave up and just photographed the trash itself.

While the beaches were pretty different from prairies, the dunes right next to them felt much more like home. As I walked through them, I felt as if I should know the plants I was seeing. They looked just like prairie plants I am familiar with in Nebraska except that they weren’t quite. I saw grasses that were almost prairie sandreed, wildflowers that were almost purple prairie clover, and many others. If I squinted my eyes, it felt like home.

The plant community in the dunes looked and felt just like the sandhills prairie of Nebraska.
Not only did walking the dunes feel familiar, photographing the little creatures living in them did too. I heard this cicada before I saw it, and was able to slowly creep up close enough for a photo.

Grasshoppers were very abundant in the dunes. Every time I stopped to photograph one, I’d see several others right next to it. The result was a kind of neverending cascade of photographic opportunities. Even with a stiff breeze blowing, I managed to get a few decent portraits taken.

Lizards were also a comforting sight. The habitat looked like it should have lizards in it, and sure enough, there they were. I had to look up the species online (I think I got it right)?

I’m not sure if the more colorful one is a juvenile or different gender – I couldn’t figure that out online, but I’m sure readers can help me out. Padre Island National Seashore.

As always, it was great to be on vacation but nice to be home again. I enjoyed walking through the familiar black-eyed susans and big bluestem of the Platte River Prairies yesterday.
Though I do miss those crabs…
