Fuzzy (par MerMate)

Costasiella sp. found on Avrainvillea sp. algae, with a ribbon of eggs.

Beautiful photo of a cute Costasiella sea slug, showing the tiny black ocelli close together between the pair of long and dark rhinophores, and the cerata (finger-like projections), pink at the tips and filled with green stuff.

This is one of the genus in the Limapontiidae family (order Sacoglossa) whose species have the ability to symbiotically retain functional chloroplasts within cells of the digestive tract.

I wonder how many people scrolled by thinking this was an artichoke or a cactus on their dash.

Everyone take a moment to appreciate that it has a little white face with ridiculous beady black eyes (and yes, those really are the eyes)

Don’t Cry For Me, Arthropoda: Studies Find Signs of Emotion in Spiders

Individual spiders have character and personality, according to a paper published by theProceedings of the Royal Society B. The paper, titled Individual personalities shape task differentiation in a social spider, gives details of a study into role allocation in spider societies.

It was previously assumed that individuals in social spider communities contributed homogenously, with all tasks, such as prey capture and colony defence, being performed equally by members.

The study focused on Stegodyphus sarasinorum, a permanently social spider occurring in India and some surrounding countries. Led by Lena Grinsted of Aarhus University in Denmark, over 600 spiders were marked and observed, with tests singling out boldness and aggression. Variances in response showed that individuals were suited to particular roles. 

Individuals in the test group were highly related and of approximately the same age: the only variable was apparently their personality. The study suggests that task allocation is the result of character traits in individual spiders; personality does not appear to be shaped by random selection of task perfomance, therefore.

Character and personality are often attributed only to humans, higher order mammals, and birds. Now it appears that arthropods also have responses that could be considered emotional.

Help save the honey bees! Please reblog and share :)

I’m very skeptical about this. Last I’ve heard, CCD is caused by a combination of factors, and to blindly point a finger at one source without references just ticks my bullshit meter. Anyone got science to back this up?

I checked out this page on the Ontario Beekeeper’s Association website, and found a couple of recent papers on the subject (though, granted, they are against the use of neonicotinoid, so it might be a one-sided story). The general consensus seems to be (bee?) that sublethal doses of neonicotinoids cause changes in behavior and physiology which leads to colony collapse - immune suppression to make them more susceptible to disease, negative change in foraging behavior, abandonment of poisoned hives, etc - so, yes, it seems that it is a combination of factors, which are aggravated by pesticide poisoning.

I’ve seen a bunch of “save the bees” post floating around tumblr, but this is the first one anyone bothered to put sources on.
Thank you. (However I’m not going to look at the sources now, but hopefully I will remember to do so later.)

Not to mention that stopping the use of these pesticides is one of the easiest things we could control— if people were willing. It’s hard to control parasites and internal issues that the bee faces, but it is not hard to stop spraying crops with harmful pesticides.

I recently posted a photo such as this, where I’m holding Linda the Black Widow,  on my blog and the comments coming in are kinda cracking me up.
Here are a few:
“what is photoshop”-
Well, if you knew me personally, you’d understand why this is funny.  I am so computer illiterate I could never use photoshop- you’re lucky I know how to use tumblr…. Also, if you follow me, you know I hold all things “creepy” on a regular basis.
“this bitch really let a venomous spider bite her trying to be cute”
Apparently, I’m a bitch?  And who said Linda bit me?  I didn’t!  Black Widows are extremely shy and non-aggressive.  They are nothing to be afraid of, like any animal, if treated with respect (which usually means just leave it alone) and not threatened, they will not feel the need to defend themselves.  I was not “trying to be cute”..  The point of this blog is to educate others about the natural world.  Me holding a venomous beneficial black widow reinforces the point- most of the negative feelings people have towards spiders are based on irrational fear.
“Now they call her rotten hand”
Once again, you’d practically have to force a black widow to bite you.  Also, even if she were to bite me, it certainly would not rot my hand.  Black widow venom is a nuerotoxin, and does not cause necrosis.

I don’t like the Johnlock ship

the-mad-march-hare42:

I don’t like shipping in general, but I do HATE Johnlock, simply because I am a fan of Sherlock, but I am also a fan of the original books and the Granada television version. Whenever I see a Johnlock ship I just think about the original Holmes and Watson and shudder. It’s just a set of stories about two BEST FRIENDS solving crimes and having adventures. Can we just believe in friendship once in a while without drawing lust out of it?

Also, Holmecest? Really? Yuck.
