THRILLED to share this compilation of heartfelt stories about the Kona manta rays. To us, they are not just fish but have names and personalities. Let the gentle giants guide you through 2025! Plus, let’s increase awareness about the recurring higher probability of encountering box jellyfish along Hawaii’s leeward shores. The phenomenon occurs monthly, and this wall calendar shows when to anticipate them.

What I love about this book is it's simplicity in bringing light to really important topics around marine life and the ocean. I have had the privilege see Martina & Manta Ray Advocates work first hand and It's so powerful to see the message of marine life awareness being spread in such a fun light-hearted way. Great for kids and adults alike!

I got stung by a jellyfish when I was young, and it was NO FUN. This is a tremendous resource.
