Starfish {InstaScience}

June 23, 2016 by Paige Hudson

These beautiful invertebrates have no heart or blood, but they are the stars of the sea! Come learn about the amazing starfish in an instant!

One of my favorite animals in the sea is the starfish – I love the variety and beauty of these amazing creatures! And I feel that beach science month would be incomplete without us chatting about these marine animals.

Starfish are also known as sea stars. These marine invertebrates are part of a group known as echinoderms. Echinoderms are animals with spiny skin and sucker feet that all have radial symmetry. Marine creatures like starfish, sea urchins, sand dollars, brittle stars, and feather stars are all echinoderms.

Sea stars have no brain, no blood, and they have the weirdest eyes. They typically have five “arms,” but they can have up to fifty! These arms are covered with tube-shaped sucker feet that help the animals move and grab prey. They typically eat small mollusks, like sea snails and clams.

There are over 2000 different species of sea stars. These invertebrates can be found in the depths of the ocean all the way up into the tidal pools. However, they cannot be found in fresh water.

Fun Fact – Starfish eat with their stomachs inside-out.

Welcome to the Elemental Blogging Laboratory

 
profile picWelcome to the Elemental Blogging Laboratory, a.k.a. the Eb Lab. Here at the lab, I have the pleasure of sharing with you all my passion for mixing up solutions for homeschool science! My name is Paige Hudson. I am a homeschooling mom and science curriculum writer for Elemental Science.
 
Why do I call this blog the "Eb Lab"? It is because I am scientist at heart and by profession, so it pretty much spills into everything I do. I love to share tips and tools with fellow educators as they seek to share science with their students!
 
That is what this blog is all about. One homeschooler to another, sharing her area of expertise, seeking to support you as you teach your students about the wonders of science.
 
So, grab your lab coat, notebook, and goggles...well maybe not the goggles because let's face it nobody looks good in those...and you probably don't have a lab coat lying around your house either...
 
So, grab a cup of coffee and notebook, and head on in to the Eb Lab to gather tools for homeschool science, tips for homeschooling, and the latest Elemental Science news!
