The butterfly's antennae, palps, legs and many other parts of the body are studded with sense receptors that are used to smell. But when it comes to travelling for migration, they have an inner magnetic compass to navigate their way to warmer parts on earth in order to survive. 
Butterflies have these light-sensitive molecules called cryptochromes, that can very easily detect small changes in the earth's magnetic field, They use UV light to power these cryptochromes. ]]> 2018-04-23 14:59:03 UTC https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254435964 https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254437202 .Travel very little and always stay close to their breeding ground due to their small size

They use magnetoreception which allows them to detect the earth’s magnetic field. Once turtles are further out at sea, there are magnetic fields unique to different geographic locations which function as navigational markers that make sure turtles stay on course whilst migrating. ]]> 2018-04-23 15:03:45 UTC https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254438734 https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254439714 Turtles make long and dangerous journeys to return to the beaches where they were born no matter the distance. Sometimes they could be thousands of miles away and will still travel the distances. Turtles are very good navigators and have the ability to detect the earths magenetic fields even before they venture into the sea which acts as another sense as their vision is very poor. 

By detecting the earths magnetic fields it allows the turtles to plan their courses/journeys whilst in the sea, which makes it easier to remember where the best mating and feeding spots are and they will return to these areas over and over again. Which also is how they find their ways back to their original beaches. 

They return to these beaches as they are most likely to provide the most for their offspring, have less predators and will make it more likely for them to survive.

They have a very good sense of smell, taste and hearing which means they are good at finding food and sensing danger. They also use their lateral line to sense vibrations of potential predators within the ocean or along their journey. Scientists aren't 100% sure how the salmon can find their way home, but they believe it's to do with remebring a specific odour of their home stream.]]> 2018-04-23 15:08:03 UTC https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254440962 https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441170 2018-04-23 15:08:32 UTC https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441170 https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441389 They are born in fresh water and soon travel to sea water where they spend most of their life, however when they are ready to breed they will travel about 1000 miles back to their home in the fresh water. They tend to migrate in the autumn. They use magnetreception to locate the general position of their natal river, once close they use their strong sense of smell to home in on the specific spot. It was found that the smell of the river becomes imprinted on them just before the young salmon move out to the sea. Soon after reproducing they die. ]]> 2018-04-23 15:09:00 UTC https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441389 https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441466 They go on a 3000 mile migration across the United States. These butterflies are known for using the suns position for directions but if they can't see it they use an internal compass capable of sensing the earths magnetic field to navigate themselves during this journey. They migrate from the Rocky mountains to Mexico]]> 2018-04-23 15:09:08 UTC https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441466 https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441525 These fish are born in and live in fresh water as juveniles, migrate to the sea as adults before returning to their native river in order to spawn. They will migrate to the Norwegian sea before returning to Scottish rivers. The fish will return to the same river they were born in after spending 1-4 years at sea. They can even return to the same stretch to river. Here they will spawn before dying. ]]> 2018-04-23 15:09:16 UTC https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441525 https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441650 A single migration journey is completed through around 4 generations of offspring due to their short 2-6 week life span. They perceive ultraviolet and polarised light- light waves that move in only one direction and they sense that direction for migration. They have a pair of molecules in their brain that are sensitive to the earths magnetic field and they use this as a compass alongside the positioning of the sun to find their way to migrate to the south. ]]> 2018-04-23 15:09:30 UTC https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441650 https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441703 2018-04-23 15:09:34 UTC https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441703 https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441726 They are born in rivers, and normally hatch in the spring time. They live in the rivers for 2-3 years however this can depend on the amount of food there is and the temperature of the water. They start to leave the rivers when they are old enough and start thier journey to the ocean. Which is usally around the faroe islands and southern norwegian rivers.They tend to travel in groups when migrating. They remain in the ocean from 1-3/4 years before returning back to the river.]]> 2018-04-23 15:09:37 UTC https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441726 https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441745 The monarch butterfly is the only insect that survives by making a 2,500 mile journey every year in order to survive. As the lifespan of most adult monarch butterflies is 2-6 weeks this journey is completed through 4 generations. Every year they return to the same tree as the fourth generation before them, without having been there before. They do this by having an internal map and compass that is innate. At the very least they are born with an instinct to complete migration. They use the position of the sun as a compass, every journey they travel south. In addition to an internal clock they have a magnetic compass which gives them keen sense of direction helping them detect the equator.]]> 2018-04-23 15:09:39 UTC https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254441745 https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254442232 Stay close within their nest whilst foraging for food for their babies using their strong sense of smell]]> 2018-04-23 15:10:34 UTC https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254442232 https://padlet.com/catherine_knight1/ri8fmynej9sr/wish/254442361 A monarch butterfly’s antennae, palps, legs,and many other parts of the body are studded with sense receptors that are used to smell.
