The Humble Cacti 🌵

There are over 2,000 different species of cacti which are native to deserts and dry regions of South and North America. They tend to be the first plant people buy due to their lack of needing water, but we have been told by many people that they end up giving their plant too much love.
The spikes you can see in this photo are technically called spines. These protect the cactus against herbivores, and can also help prevent water loss by reducing air flow close to the cactus and providing some shade.

With a sweet scent comes the waxy flower of Mammillaria plumosa (feather cactus, tollaskaktusz), native to Northeastern Mexico. It's a beautiful, feathery spined addition to #mywindowsillgarden.

remember my ‘ugly’ plant? the part i cut off (and didn’t like) keeps on growing and the part i wanted to save is shrivelling.. the cut off part doesn’t even have roots?! look at that green bit on top, it has grown 3cms! and you can even spot a new leaf.. 🤯🤔🙄 #swipeleft #weird #uglyplant #typical #karma #spines #weirdo #cactus #ugly #newgrowth #newleaf #swipeleft⬅️ #cactus🌵 #plantstagram #plants #plantsplantsplants #plantsofinstagram

When you can bring home plants for you significant other ❤

As I'm working in a nursery I get constantly so excited about special plants. The downside is I cannot bring all of them home because I'm no millionaire rather do I have space for all. Sometimes if I really like one I send my partner a pic of them and if I'm lucky he wants to adopt them! That's what happened with this beautiful Ferocactus chrysacanthus. He stood out of all the others because his spines were more curled and dense. I just loved him from first sight and am very happy that I can take him to my lovely significant other.

I finally found Shim in the LAST moving box I opened. I was determined not to start any indies until I finished this one! So finally CR Shim, and what a well written and great story so far. @dyllonlfoster had me bragging on her skills to my hubby. It’s almost my daughter and son’s bday, so we are celebrating with a Disney cruise. Here’s my cruise stack including another indie fav @andy_zambrano_author . We are still in total chaos from moving and life events, so I’m thinking the next book buy will be mid December. 📚 🚢 📚 🌊

Have you ever read a book that started strong but then sputtered out (at least for you)? That’s how I felt about Caraval, I really loved the first 100 pages but then for some reason I couldn’t get into the story. Maybe it’s because I couldn’t accept the premise? Or maybe the magic system wasn’t for me? For all intents and purposes, this is a book I would usually enjoy 😢 I honestly can’t pinpoint the reason, but I just found myself not caring about the characters.
I’ve heard good things about the other books in the series but think I’ll sit out. If the author starts a different book or series, I’ll certainly check it out.
What did you think of Caraval? Who knows? I might give it a reread at some point. .

I’m participating in the #bareyourspineschallenge even though it physically pained me to take the covers off of my books. They are shivering right now. It’s all for the gram. So QOTD: do you take the cover off your books?

Snagged some beautiful #christmas gifts for my family from @greengorillaokc recently. This will probably be my new head shop in the city for all of my paper and glass needs. Everyone was super kind, knowledgeable, and fun to just chat with. •

Second year students preparing and analyzing ctenoid fish scales and spines, which were collected from fish camp as a non lethal form of aging. Scales are rolled and pressed while spines are placed in epoxy and cut very finely with a sectioning saw before they can be aged. This method of aging requires you to count the annuli, similar to counting the rings on a tree. Thanks to @chip_mclaughlin for sharing!! #fishandwildlife #flemingcollege #frostcsmpus #scales #spines #aging #fish t

Happy Hump Day! I’ve got PTO coming up at work and can’t wait for a proper break. In the meantime, there are a ton of deadlines to handle 😪
How’s your week going? I’m 147 pages into Ninth House and can honestly say that the story has finally picked up for me. How long do you think is too long to get into a book? Some stories just catch my interest from line one while others are a slow burn. I really don’t mind either scenario as long as I care about the characters or relate to them a bit. .

👶🏽 A STEEP LEARNING CURVE 👧

STARTING PAEDIATRICS. So it's been a week now of working with children/young adults who come in for a range of complex spinal surgeries, spinal cord injury rehab and treatment/removal of rare cancers of the bone & soft tissues (I.e. sarcomas). One of the main differences that I've noticed between working with kids and adults is:
.
🧐 The negotiation skills needed for both the children AND their parents/carers! Everyone needs to be on board with your plan so there's a lot of close working with other healthcare professionals too e.g. play therapists, physios, speech therapists, doctors, nurses, occupational therapists, care workers and many more!.
.
💉 I've also had a taster of using parenteral nutrition [(PN) given into the veins (IV)] for really poorly children who don't have a fully functioning digestive system. It's the last resort if people can't tolerate oral eating and drinking, or tube feeding into the gut (see the previous tube feeding post for more info on this!). The aim is to build them back up from PN to tube feeding or eating orally if we can!.
.
🌪 What a whirlwind! I happened to start my paeds journey now, when the wards are more busy that usual, with lots of surgeries being sent our way from all over the country.
.
😊 It's been emotional but fulfilling nevertheless and I definitely needed the reminder above - a great little message from @mellow.doodles .Taking it one day at a time & in most cases, one patient at a time! It really helps to focus the brain when there's so much to do, your head feels full to the brim and you're worried you might forget something!
.
🧠 Thankfully, I now have time to take some annual leave for a brain break!
.
Let me know if there are any nutrition questions or topics you would like more info on below!
.
Happy Wednesday 🎉

Hedgehogs have peculiar #foraging methods: it emits pig-like grunts as it picks it’s way through hedges - hence their name =D These cute creatures have a typical diet consisting of insects, small creatures, and berries - they root through hedges and undergrowth in search of their meals and are strong enough to take down a viper and eat it too! There are 17 different species of hedgies and they’re all #solitary creatures, typically #coupling only for mating. Perhaps it’s because of their hair? Haha.

#Hair is a defining feature of #mammals because it is only found in mammals (every mammal has hair at some point in its life). Over the course of mammalian #evolution, hairs have been modified and specialized to perform many functions, including insulation, camouflage, signaling (to potential mates or potential predators), sensing (via whiskers or vibrissae), and in the case of HEDGEHOG’s- #defense. They have modified hairs that are enlarged, stiffened, and strengthened to form #spikes of different shapes and sizes. These structures, called #spines or sometimes #quills, always have a thick, hard, outer tube of #keratin (the fibrous protein that makes up all hair as well as claws, nails, and horn sheaths) and tapered, pointed tips. Spines and quills are terms often used interchangeably, but they have slightly different definitions. “Spine” is a more general term for any hair that has been modified into a hardened, spiked structure, whereas “quills” are a specific type of spine. Both evolved independently at multiple places and times in the mammal tree of life, thus they are an example of #convergence. The oldest mammal known to have enlarged, hardened hairs for defense is #Pholidocerus, an #extinct ancestor of the hedgehog that lived over 40 million years ago. However, hairs do not #fossilize as readily as other structures like teeth and bones, so spines and quills may have evolved much earlier. We don’t know =)

Top #spines posts

The crown-of-thorns starfish is a sea star named for the spines that cover its body and arms. These starfish are known to be more successful at preying on large swaths of coral reefs when the corals are already stressed. During times of coral bleaching or stresses caused by human activities, outbreaks of the crown-of-thorn starfish may be particularly destructive. Scientists consider it a species of concern - not because its numbers are too low but because locally high numbers can threaten other species. Learn more about these voracious predators and how Oceana works to protect our oceans and coral reefs from the sort of threats that these starfish exploit in our Marine Life Encyclopedia at OCEANA.ORG/MARINE-LIFE

The crown-of-thorns starfish is a sea star named for the spines that cover its body and arms. These starfish are known to be more successful at preying on large swaths of coral reefs when the corals are already stressed. During times of coral bleaching or stresses caused by human activities, outbreaks of the crown-of-thorn starfish may be particularly destructive. Scientists consider it a species of concern - not because its numbers are too low but because locally high numbers can threaten other species. Learn more about these voracious predators and how Oceana works to protect our oceans and coral reefs from the sort of threats that these starfish exploit in our Marine Life Encyclopedia at OCEANA.ORG/MARINE-LIFE

You’re looking at the only species of venomous sea star in the world - the crown of thorns starfish. While this species has no ability to inject toxins like a bee or wasp, their sharp and brittle spines can penetrate flesh easily, causing severe, stinging pain, swelling, and even nausea. These spines help this carnivorous sea star prey upon hard, stony coral polyps. In the wild, this species is found in the Indo-Pacific, and are one of the largest sea star species with a wide distribution. You can protect this and other marine species by keeping waterways clean. Properly disposing of trash and reducing your use of single-use plastic items keeps debris off of the ground, reducing the likelihood of such items being swept out to sea.

#Pufferfish do not have #scales, but their skin is #thick and #rough and some #species have #spines on the #skin, which offer additional #protection against the #predators.

Puffer fish can be #discretely or brightly #colored. There is often #relationship between the body #coloration and the amount of #toxin produced by the #fish.
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
#BrighterColors are often associated with large #quantity of toxin in the fish.. #Sharks are the only species #immune to the #puffer fish's toxin. They can #eat puffer fish without any negative #consequences.
