    I voted for one but really, quite happy with all and any of ’em.

    Huge detailed version and key:

    Confocal image of squid, Loligo pealei, embryo stained for for F-actin (green; phalloidin), Acetylated tubulin (red), anti-HRP (yellow), and DAPI (blue; nuclei)

    I kind of like the other squid embryo* better, though: check out that nervous system!

    or, yeah, just clicking on the OP pic is another way to see it giant and detailed. Just noticed that.

  4. ChasCPeterson says

    When you look at the enlarged version, a lot of the red spots (= tubulin) appear to have little tendrils. Are these the spindles of dividing cells (seem to large relative to the blue-stained cell nuclei), or are these maybe developing chromatophores?

    This image reminds me that I’ve yet to see a post about Prometheus. Did I miss an episode?
    Because between the [spoiler] creationism with Greys on steroids and the baby squid raping facehugger (who somehow looks like today’s image), this movie is perfect fodder for this blog [/spoiler]

  6. Cuttlefish says

    Captain Pharyngula has no heart.

    I, on the other tentacle, have three, so these things even out.

  7. naturalcynic says

    A must vote for the 5 pointed squidling star. The 5-pointed star is the sign of evil and I bet those squidlings are communicating their final evil intentions before they separate and conquer the seas.

  8. coralline says

    The “5-pointed squidling star” is gorgeous. But it’s apparently the same image repeated 4 more times, with different filters to emphasize different active sites. That smacks of Photoshop-like stuff. Surely the same 5 images arranged next to each other would be a more effective pedagogical/research tool.

    I think I’d rather see one image with the different colors included, to really get a sense for what’s going on.
