Yet all these shells will display the same principle of how there are grown by the mollusc and the 3 mathematical rules that determine the variations of the spiral. Should you travel further afield than northern Europe the spirals in shells become more varied and elaborate. how much it moves out from the centre on each turn.The video below gives you an idea of how all the different shells we see all conform to the same factors that determine their shape. Yet spirals come in all forms, it takes just three factors to change the shape of a spiral. With some of these flatter bivalve shells the actual spiral is difficult to see because it is so distorted from what we expect a spiral to be. But you can see very easily how in this article the shape of shells is made and that actually the bivalve are also spirals. Often you will only find one half which we call the shell. Mussels, Clams, Wedge, Cockles to name just a few. There are so many variations to be found of just these types which you will see clearly how a spiral is the home of the mollusc that created it.Īlso look for the bivalve shells. Seashells – I mean where to start? (just on UK is a good idea) Whelks and Periwinkles, Top shells, Limpets. That is the concise explanation! and enough to keep us in awe and wonder as the myriad of spirals in nature there are to be found Spirals in the Shells The angle of the the growth is commonly know as the Golden Angle which is the ratio between the Fibonacci sequence of numbers. Its a simple nature craft that encourages the observations skills and involves the hands and the eyes.Ĭlose up of a tansy flower showing interconnected spirals in natureĪgain this area can be looked at with our Fibonacci goggles on if you want. The brief explanation would be the cells that grow in the tip of the shoot do so in a helical (Helix) spiral pattern as it happens to be the most efficient way to pack the ever growing/moving cells. I often run a workshop with The Smart Happy club where we paint in the spiral onto the pine cones. Also at the other end of the flower cycle the seed formation often clearly presents a multitude of interconnected spirals. Spirals in Nature’s seedsįlowers often display a spiral pattern. Although appearing to be an insignificant part of the plant, this is an example of a helix when in use. These tiny delicate spirals are the pistils (i think!) that are part of the reproductive ovary of the Magnolia plant These spirals in nature are the tendrils of pea plant. Often called a fiddle fern because of the resemblance to a violin scroll, there are so many fern types to see. There is nothing more glorious than seeing those young ferns unfurl in early spring. You can clearly see the spiral as a flat curve in ferns, but also as a 3D spiral in petals as they unfurl around the flower bud. Plant forms have both types of spirals that we observe. There are many fossil types but the Ammonite fossil is the spiral we are looking for and easily found along this stretch of this Jurassic coast in the UK both in calcite and pyrite forms its definitely worth a day trip. What the tourist industry along the UK’s Dorset coastline is built on – Fossils. Here you are looking for the flat curve spiral. a 3D spiral (like a spiral staircase) also known as a HelixĬalcite fossil fossil imprint in beef rock spirals in rocks.Spirals in Nature occur in many forms, but for us to find them, it is helpful to think of just 2 concepts. 2 types of Spirals in Natureįirstly a little distinction. The lists below will give you tips for where to look, but why look for shapes in nature? is also what the Smart Happy Project is about. Improving observation skills is the first step to enjoying nature and building our relationship to it. Looking is the key to finding Spirals in Nature (no way Lisa, you’re not kidding?) I know, obvious, but you’d be surprised how little we see things sometimes. You will see how the patterns of spirals in nature indicate the mathematical rules of growth. I have also compiled more info on the maths in spirals or particularly on how Fibonacci numbers manifest in nature, and how to spot the interconnected spirals in a sunflower so be sure have a good look around the Smart Happy Project website.īut, don’t let the maths and numbers put you off, what is important is to look and to be amazed by these spirals in nature, then your wonder will surely grow. A list of Spirals in Natureīelow is a fairly comprehensive list of where to look to easily find naturally occurring spirals. From seashells to lizard tails to delicate unfurling ferns and slices of veg, you won’t be disappointed. Read on if you want to find them and fall in love too. This is my love letter to Spirals in Nature. Where to start about Spirals in Nature? I mean there are so many!
