Moon snail [WDFW/Kevin Lee]

Moon Snail Euspira lewisii
One of the best-known invertebrates in the sandy intertidal zone is the Moon Snail, both because it is a large (up to 13 cm in diameter) species and because its egg masses are especially notable. Moon Snails are voracious predators on the clams that share their habitat. They find a clam, presumably by chemoreception, and envelope it in their big foot and often drag it more deeply into the sand. The radula has seven rows of teeth, with which they dig a hole (easily recognizable as made by this species because countersunk) into the clam shell. A gland on the proboscis secretes enzymes and even hydrochloric acid to help accomplish this. The snail then rasps and sucks out the clam’s tissues over a period of a day or so.

With an election approaching this fall, the BC NDP government has released a surprise update touting ‘significant progress’ on protecting old-growth forests. We take a look at the reality on the ground. Shannon Waters reports. (The Narwhal)

Will climate change cause more WA beach closures because of algae or bacteria?
It’s unclear how climate change might affect closures in the region. But generally algae thrives in warmer water and bacteria is commonly washed into waterways, mostly from animal feces. As summers get hotter, access to cold bodies of water will become more important for people who don’t have a place to cool down. Amanda Zhou reports. (Seattle Times)
