Whelks to Whales: Coastal Marine Life of the Pacific Northwest
Newly Revised and Expanded Second Edition
Rick M. Harbo
Harbour Publishing Co., Ltd., 2011
Madeira Park, BC

The first edition of Whelks to Whales has been our go-to reference for all the strange and colorful creatures we find in tide pools. We usually bring it with us on our expeditions and look at it as soon as possible.

The second edition is larger by more than 80 pages. Particularly of interest to us was a new section on egg cases, which allowed us to specify the squid egg mass as being those of the opal squid. That alone was reason enough to snap it up.

In addition to the new section, the book as a whole is better designed and laid out, with a more readable typeface. Many species have new information, whether updated population surveys (the first edition was published in 1999), new research data, or a more detailed description. There were also new species in almost every section I checked.

The photographs are largely the same, but they were good in the first edition. However, there were many different and new photographs, and not just of new species.

All in all, this is a genuine revision and update, and well worth buying even if you have the first edition.

And now some of the tidepool life we saw at Salt Creek this year.

We (my wife and I) like tidepools because they’re so full of tiny creatures. Every square inch might be taken up with something: anemones, sponges, corals, seaweeds and grasses, sculpins, mussels, bivalves, crabs, shrimp, limpets, and on and on. The tidepools at Salt Creek, being on a very rocky shore, are fun to explore on their own. There are dozens and dozens of little enclaves of life, in many different nooks and crannies, some being washed by the waves no matter how low the tide, some covered in only the highest tides.

Tidepools make me think how profligate life is, how every nook and cranny will be filled with something, and how nothing is wasted. It’s also very colorful: either the exuberant coloration of a poisonous or unpalatable life form, or the dramatic mottling of something trying to camouflage itself against a chaotic background.

I remember thinking “sometimes, all you want is a straightforward, simple picture of goose-neck barnacles.” I should take this approach more often, as I want my photography to be more documentary or objective.

But sometimes it’s hard to avoid the artistic.

Purple Shore Crab (Hemigrapsus nudus)

We watched this little guy eat for a while. It would reach into the mussel shell, struggle for a second or two, and then pull out a tiny little chunk of the mussel meat. A barely visible (to me) portion at any one time, but the crab didn’t have to go anywhere and the mussel certainly wasn’t going to run away. On the other side of the mussel (not photographable due to sun glare) was a much smaller shore crab, like a child or younger sibling.

This is a good example of the density of life in a tide pool, the area you’re looking at is only a couple square inches.

Pink-tipped Green Anemone (Anthopleura elegantissima)

Even though the pink-tipped anemone is the subject of this photo, there are hermit crabs, limpets, algae, encrusting corals or sponges, and other life forms in the field of view, if not necessarily visible in the photo.

Also, I like the word “elegantissima.” The “ti” should be heavily accented, and the “ss” very sibilant. Ell – ehh – gan – TIss – ih – mah.

Here is the complete set of photos from Salt Creek this year. Here is a collection of tidepool and tideland photographs from other trips.
