5 Cool things about Octopuses!


Hello welcome to the third day of blog every day in April….

Today I have literally no time at all (so much so this got written weeks ago) however I still want to tell you 5 amazing things about the humble octopus! Let’s go!


Number 1: There are approximately 300 recognized species of Octopus!

Number 2: All octopuses are venomous but only small blue-ringed octopuses are known to be deadly to humans.

Number 3: Octopuses have three hearts. Two pump blood through each of the two gills and the other pumps the blood through the rest of the body!

Number 4: Octopuses are really intelligent. They can use tools, open boxes and they can learn by observing another octopus. They are also amazing escape artists! In fact here is a video of an octopus escaping through a 1 inch diameter hole!

Number 5: Octopuses have been observed playing with toys! They even all have individual responses and temperaments. This has led to some theories on octopuses having individual personalities.

To summarise, octopuses are pretty cool. A truly fascinating group of species that I’m sure we’ll find lots more about in the future!
