Baby octopus:
tealdearest asked:
I thought dragon wing begonias were as cool as they got! Did you get it from where you work??? I've never seen one where I shop for plants
plantanarchy answered:
Yep! Begonias can get SUPER extremely cool. They’re one of my favorites and there are about 800 kinds…
Rex Begonias are usuallyyy sold as annuals in spring to go in shade combination planters. At my old greenhouse job, the only weird begonias I’d seen were Escargot Rex begonias
And also Pegasus/Gryphon begonias
Rex Begonias and other rhizomatous begonias are usually the most awesome and varied foliage wise. Here’s my others:
One of my favorites and plants I really want is Begonia maculata ‘Wightii”
Also… Begonia luxurians
And Iron Cross Begonias are cool
And also, my mom has hardy begonias which are super cool. They’re hardy to zone 6.
But yeah… begonias
Begonias are really cool. Some species are really, really cool, like Begonia ferox and locii.
B. ferox and B. PAVONINA! are two big reasons I’d like to try a large terrarium one day!
Shy Octopus Turns Serious Scientists Into Total Softies
If you’ve never heard scientists awwww at an octopus before, here’s your chance.
Octopus filmed changing colours while sleeping.
i wonder what they are dreaming about
Changing colors duh
What’s really cool about this is that cephalopod (octopus, squid, etc.) intelligence evolved completely separately from intelligence in tetrapods (which includes primates, dolphins, crows… basically any other intelligent animals you can think of). Cephalopods are very, very far away from us on the tree of life. For context, you and a starfish are more closely related than you and an octopus. The last common ancestor of humans and cephalopods was the so-called Urbilaterian, the hypothetical first animal with a left-right symmetric body. This animal almost certainly had, at most, an extremely simple nervous system, without anything resembling a brain.
All this is to say that the fact that this octopus appears to be dreaming means one of two things. Either
a) dreaming is a very, very old thing indeed, going directly back to the Urbilaterian. This would mean that almost every animal, from insects to starfish to sea slugs to newts, is likely to have the ability to dream in some capacity or another (unless they have specifically lost it by evolutionary simplification).
or
b) dreaming evolved entirely independently in cephalopods when they developed greater intelligence. This would suggest, at least, that there’s something very fundamental about dreaming related to intelligence itself, which causes it to emerge independently when sufficient intelligence arises.
Needless to say, either of these outcomes would be really very cool.
