Elasmo goes to the doctor to do a check up on his 5 Senses!

ELASMO - A visit to the doctor

Time to check your electric and pressure sensors! You need these to work well because this is how you feel what is around you! You use them for hunting and to protect yourself. Your Ampullae of Lorenzini detect the electricity made by moving muscles and your lateral line senses changes in water pressure.

Close your eyes and tell me when you can feel ripples in the water!

Activity: Blow on your hand. Feel the air pressure change. This works like Elasmo's lateral line feeling changes in water pressure.

Hello Elasmo, swim on in! I'm in the second cave on the right.

Stars pattern

Ear covering: okay Range of hearing: 250 m

That light is hot on my ear! Can you see my ear covering?

Activity: How far away can you hear sounds from?

I'm excited because I'm going to see Dr. Sue Octopus for my annual checkup! She's going to check that all my senses are working properly!

But... I can't remember how to get there! I wonder if there is someone around to help me?

Now we need to see if you know the difference between good and bad blood.

I'm going to put some blood into this Olympic-size swimming pool - Tell me when you can smell it!

Looking good! This means you have stereo-smell! So you know which direction the smell comes from.

Great! That's the only type of blood here that you're attracted to!

NOW! I can already smell fish blood.

Amazing! You can already smell the blood after only ONE drop!

Very good, you have excellent sight! Now we'll check your hearing.

What strange noises!

Activity: Play the noises - what do you think they might be? Sea lion barking? Fish flapping in water? Something else???

First we will need to check your eyesight. Please read the chart.

Easy! I can see all the way down to the dolphin!

Now let's have a closer look: Your 3rd eyelid is intact and the back of your eye is shiny! This will protect your eye and help your night vision.

A third eyelid?! Activity: Do humans have a third eyelid?

This project was funded by the Erasmus+ Programme

Elasmo, your nostrils are clear. All is well.

Sense 1 drop of fish blood in Olympic-size swimming pool (2.5 million liters!!!!) 100 times better than a dog Stereo-smelling Attracted to fish blood

Activity: Can you identify which smells will attract a shark?

1 Nictitating membrane 2 Can see small fish at 15 m away 3 Low-light sensitivity 4 Can see colours 5 Reflective back of eye: shiny

Activity: Can you match the pictures to the checklist?

Activity: What is your favourite meal? Can you tell us why?

WOOHOO! We made it! Just need to go through the arch and in through the main entrance.

ELECTRIC AND PRESSURE SENSES Lateral line detects pressure changes Ampullae of Lorenzini can detect electrical fields Can sense fish heartbeat when it hides under sand

Elasmo, well done! Your annual medical says you are 100%. Off you go and I'll see you next year!

Thank you so much Dr. Sue Octopus! Goodbye!
