Atlas moth / Scientific name: Attacus atlas Department: Entomology, image © California Academy of Sciences The Atlas moth is one of the largest moths in the world in terms of wing surface-area and wingspan, and perhaps most famous for the markings on the upper corner of their wings, which bear an uncanny resemblance to cobra heads (in profile). While not all entomologists are convinced of that visual mimicry, there is some convincing evidence. Cobras live in the same part of the world as these moths, and the moth’s main predators—birds and lizards—are visual hunters. Plus, species related to the Atlas moth have similar but less defined versions of the snake’s head, showing a pattern that could have been fine-tuned by natural selection. #scientificcollections

Look for @maggiewest ’s newest collaboration with #CASNightLife tomorrow night! She recently visited our Ornithology & Mammalogy collections to photograph a range of scientific specimens, and we’re thrilled (us: 😍) to see them through her surreal lens. This is a mountain lion skull (Puma concolor), recovered and collected by the legendary Ray Bandar, whose incredible contributions to science continue to live on.

Yes, our green tree python may be looking straight into your soul, but at least it’s not using its built-in sensory organs to look at your infrared heat and hunt you down, right? This beauty, found in “Color of Life,” was 📷 by @mrjoemorgan.
