Six-year-old draws 100 animals for Sir David Attenborough's 100th birthday!

Meet six-year-old Max, he is a David Attenborough SUPER fan.

In fact, he describes himself as Sir David's "biggest fan".

So, of course, with it being Sir David Attenborough's 100th birthday, Max decided to celebrate in a very special way.

By putting pen to paper and drawing 100 of Attenborough's favourite animals.

Max's drawing began last year for Attenborough's 99th birthday when he spent four days completing 99 drawings across eight A3 sheets of paper.

To complete the collection, Max has now drawn a platysaurus attenboroughi, also known as Attenborough's flat lizard.

He sent the drawing alongside a letter to Sir David saying: "I wanted to do something special for you, so I chose an animal named after you.

"I wanted to make it perfect and it took a while, but I hope you like it."

Max signed his letter off with a safety warning: "I hope you have the best birthday and be careful blowing out 100 candles on your cake."

Max says he has been a fan of Attenborough for as long as he can remember and said he would watch his documentaries every night before bed as a toddler.

And his love for animals doesn't stop there.

Last year Max became Britain's youngest zookeeper at Chessington Zoo.

His mum, Samantha, told the BBC that when he is older he wants to be just like his hero and present nature programmes.
