If I could release a patch for human anatomy, it’d include the restoration of a full nictitating membrane. It keeps a falcon’s eyeball from drying out during fast flight, protects vulture’s eyes from all the gore they push into while eating, creates a diving goggle for polar bears and amphibians...We lost our nictitating membrane because we didn’t really need it anymore but I want it back.

(Cats and dogs have nictitating membranes too but they’re usually kept retracted. You may see them if the animal has its eyes open slightly during sleep, though.)

The worm does not compel any water-seeking behavior, it merely makes the host jump in when water is available. However it has been noted that at the end of the worm’s growth cycle, cricket hosts do not chirp. This may be because chirping is energy-intensive (either the cricket is too weak to chirp or the worm suppresses this behavior to hoard resources). Or…perhaps the worm quiets the cricket because chirping increases the cricket’s risk of being eaten by a predator – which would put the worm at risk too.   https://www.patreon.com/alithographica

This is an example of why evolutionary trees get reorganized fairly often. Until recently it was believed that turtles were anapsids. Molecular studies indicate that they’re actually diapsids who lost their fenestra so they just /look/ anapsid. With our spotty fossil record, morphology isn’t always reliable – butsometimes it is. Some of the first evidence that birds are dinosaurs was based on skull studies. Likewise, it helped separate ancient proto-mammalian and non-mammalian reptiles.

Science Fact Friday: Caecilians! (Pronounced say-SILL-e-yun)

Little is known about how caecilians evolved but from the limited fossil record available, scientists have determined that caecilians began to diverge from other amphibians by the Jurassic period.

Unlike other vertebrates that have lost limbs (like snakes or the hind limbs of a whale), a caecilian has no vestigial limbs or pelvic/pectoral girdles. The structures have been completely lost.


   Alithographica Art  ·  January 12, 2018  ·     So you /may/ have heard that some red dye is made of bugs (though maybe you haven’t, so…now you have). But I grew up in Arizona with the bugs themselves so I wanted to give a little more attention to them than the normal “bugs? in MY food?” story. In the natural/organic vs. artificial/synthetic fight…this is a natural dye. It’s also bugs, though there are no bug parts left by the time it reaches your hands. Unless you eat strictly vegetarian/vegan/kosher/halal or are allergic to cochineal (rare) then it’s better for you than the artificial stuff, so thank our bug friends and enjoy your cupcakes/yogurt/sausage/juice/lipstick/etc.  Support Science Fact Friday on Patreon:   https://www.patreon.com/alithographica

   Alithographica Art  ·  June 1, 2018  ·     Bees use electroreception in a particularly interesting way - they collect a static charge during flight. The charge disperses on the flower when they land, helping pollen to stick to the bee but also allowing other bees to see which flowers have been visited recently.  Also: Platypus are really, really weird.  Support Science Fact Friday on Patreon!  https://www.patreon.com/alithographica

   Alithographica Art  ·  July 6,2018  ·     I do not want to rain on the tardigrade parade, but…I’m gonna rain on the tardigrade parade.  Don’t get me wrong - cryptobiosis is incredibly cool! We can learn SO many things from studying tardigrades (they also have a weird protein that helps protect against radiation damage??). But being able to put yourself in stasis to survive something is not the same as being adapted to live in that environment, and even in cryptobiosis tardigrades can and do die. They’re tough but by no means indestructible.  (that said there’s still an awesome shirt out there that says live tiny die never and I still want it very badly when will it come back to print)  Support Science Fact Friday on Patreon:  https://www.patreon.com/alithographica

   Alithographica Art  ·  June 25, 2018  ·     Sorry for the delay, I’ve been busy with pride events all weekend.  In return please have these sapphic lizards: The New Mexico whiptail is an all-female species of lizard in the southwestern United States. Even in parthenogenesis their ovaries need to be stimulated in order to produce viable eggs – so they perform mating behaviors with the other female lizards.

Science Fact Friday: Bird lungs! Just like every other part of a bird, they're weird.

This gif shows the path of a single breath, but the circuit holds 2 breaths at a time. So when the bird inhales, the just-inhaled breath goes through Inhalation 1 while the previous breath goes through Inhalation 2. Rinse, repeat. Thus, the lungs are constantly receiving oxygen - in mammals, our oxygen content dips slightly between inhalations because there's no fresh air coming in. We also don't empty 100% of our lung volume so some air is "stale" even during an inhalation.
