flamboyant cuttlefish baby & egg by Jason isley

looks as a pokeball!!! kyaaaaaa 

Studies have shown that as soon as cuttlefish hatch, they already favor whatever prey animals were visible from their transparent eggs and have already adapted their hunting strategies to the behavior of those animals.

These babies are already watching and planning what and how they are going to kill before they are even born.

hello i have learnt more spider facts

  • spiders will pull their own legs clean off if they get damaged because most of them can regrow legs during molting, which explains why you often see spiders missing a leg but never any missing half a leg?
  • some remarkably distressing scientists proved this by getting a spider to pull off all of its legs and then feeding its limbless torso for months until it sprouted a full complement of legs again and then hopefully used them to get the fuck out of dodge
  • baby spiders don’t get lenses until their first molt and before that they just have baby eyes and while this ought not to be any weirder than the concept of baby teeth, welp,
  • there are so many spiders floating around thousands of metres up in the air that they’re described as “aerial plankton”
  • The Sky Is Full Of Spiders
  • there are spider-parasitising spiders but instead of laying eggs in organs or stealing blood or anything like that they just ride on top of bigger spiders and steal snacks when their mighty steed is eating
  • there are ant-mimicking spiders that use their disguises to raid ant nests and w/e but there are also ant mimics that just. hang out. they make fake ant colonies full of fake ants. sometimes the actual ants that they’re mimicking find their house and live with them. stealth 100
  • some mother spiders live in communal family nests, where multiple mothers can work together to bring down bigger prey while all their collected babies are cared for by the babysitters
  • some mother spiders feed their babies mouth to mouth like birds
  • some mother spiders carry their babies around and i was aware of this but not the fact that if you steal their eggsac they’ll freak out and search for it for hours and sometimes end up adopting anything that’s vaguely the right size, they will carry around empty snail shells for weeks and lovingly dote on them…
  • guys i am literally about to cry over spider moms

You may know that octopuses change color to camouflage, but can these kaleidoscopic displays also communicate their “emotions?” And how do octopuses even change colors? 

Cephalopod aquarist Candace is back with our giant Pacific octopus—and a supporting cast of wild cephalopods—for some show and tell about the amazing color-changing abilities of octopuses!
