Swim, Little Wombat, Swim! by Charles Fuge

Little Wombat sort of makes fun of Platypus but eats his words when he falls into the river.  Platypus rescues him and ultimately teaches him how to swim.
A great book for introducing some animals from Australia.
*Borrowed from the library.

Australian Animals-Platypuses by Julie Murray*

Very well organized nonfiction book containing lots of information about platypuses.
Text features: table of contents, picture captions, headings, maps, bold font, fact boxes, photos, close ups, cut away, important words (glossary), index
*Highly recommend.
Point to discuss: evolution, old earth view

A Platypus, Probably by Sneed B. Collard III illustrated by Andrew Plant*

Out of the platypus books we read, this one contains the most information.
I like how the text will appeal to a wide range of ages.  The bigger font text is more poetic in form and has simpler facts for younger children.  On most of the pages, the author provides additional facts about the topic in smaller font which will appeal to older readers.
*Highly recommend.
Points to discuss: old earth view (million years), mating rituals are explained

Platypuses by Sara Louise Kras *

Pebble Plus publishing
Gail Saunders-Smith, PhD., consulting editor
I love Pebble Plus books-large pages which contain over one page spread of photos and text on the larger size.  Perfect series to use when introducing nonfiction to younger children.
Lots of fact about platypuses plus great photographs.
Text features: contents, headings, bold/colored font, glossary, index, "read more section"
*Highly recommend.

Step into Reading Step 2-Platypus! by Ginjer L. Clarke illustrated by Paul Mirocha

My eight year old is into platypuses right now so he is reading a few books about them.
Simple book which follows a platypus and its routine.  Lots of facts packed into an easy reader.
