Fishies three

We don't often see fish on the beach, except for the tiny, almost invisible, tidepool sculpins. But down at the water's edge, at the low-water mark, we found three this week. Two of them I had never seen before.

This Pacific Sand Lance was on Crescent Beach.


Ammodytes hexapterus

This was one of three, all about 6 inches long, all dead. None showed signs of injury. The mature Sand Lance grows to about 11 inches long, so these were young ones.

They swim, at times, in huge schools, and I think they are the ones I watched, years ago, off Deep Cove dock. As adults, though, they bury themselves in the sand, especially at night.
"Some species are inshore coastal dwellers, and digging for sand lances to use as a bait fish has been a popular pastime in coastal areas of Europe and North America." Wikipedia.
That's a new concept for me: digging for fish.

Wednesday we walked the low-tide level at White Rock. In a shallow pool, this white-headed sculpin lay, barely moving, watching us. He didn't burrow into the sand, the way the usual sculpins do, relying on his unfishlike shape and immobility, perhaps, to avoid notice.


Unidentified sculpin, possibly the Buffalo sculpin, Enophrys bison.

About the Buffalo Sculpin, the Marine Life Encyclopedia says, "Usually motionless and always well camouflaged ..." Stranded on a grey beach, though, the protective coloration doesn't exactly work.
"These medium sized sculpins are immediately recognizable by their proportionally large head. When threatened they will erect their sharp opercular spines which somewhat resemble the horns of bison." E-Fauna
E-Fauna's photo of a Buffalo Sculpin shows a green head. Sculpins, in general, come in a variety of colours within the same species. The Encyclopedia has a red-headed Buffalo, and a grayish one.



Crescent Gunnel, Pholis laeta.

In the shadow of the pier, we found this snake-like fish, about 7 inches long, half in and half out of the water. It is a beautiful, translucent green; the photos don't do justice to it.

In this exposed situation, (it usually hides in seaweed) its best option was to play dead, but when I came down a few inches away, trying to get a head shot, it moved away slowly, slithering snakily.


Eye to eye
Frequently in intertidal areas, in tide pools or under rocks protected by seaweeds. May remain out of water under rocks or seaweed. Probably feeds on small crustaceans and marine worms. Breathes air when out of water. Fishbase
This explains why, when the gunnel put its head underwater, it exhaled a series of bubbles. An amphibious fish on our beaches; will wonders never cease!

    Love the fish photos, we never really see ocean fish on our walks, and they are always so different looking.

  3. What a great collection. Those spines on the sculpin look as though they could do some damage.

  4. KompoStella, Sorry: I posted view photos today. Tomorrow I'll go back to critters, I promise.

    Huckleberry: I thought I knew our fish; you know, salmon, trout, halibut, cod ... normal, business-like, grey-suited fish. But it seems that the little guys are wonderfully uninhibited in their dress.

    Snail, I think they could. The fish are rumoured to raise them when threatened. "Just you dare!" perhaps?

    I hope you're feeling better.

I'm having to moderate all comments because Blogger seems to have a problem notifying me. Sorry about that. I will review them several times daily, though, until this issue is fixed.

Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
