Happy Friday, everyone! I’ve got some links for you:
1. This is a totally fascinating article about how a species of all-male clams hijacks genes from other species when they parasitize their eggs. Super freaky stuff.
2. Also, invasive nudibranchs! I love nudibranchs, but these ones are bad news, as they prey on the native nudibranchs in the Bay Area. Nudibranch adundance is correlated with warming. These “killer” nudibranchs have been moving northward over the years, acting as an indicator for climate change.

3. In octopus news, some researchers at Hebrew University have shown that an octopus can use a single arm to complete a complex task. I’m wondering how they got the octopus to refrain from using its other arms… I’m also bemused by the fact the article claims octopuses are “flexible as ballet dancers.” Come on, give the octopus some credit! It doesn’t have bones; surely it’s more flexible than a ballet dancer.
4. And, of course, a lollusk:
