The first part of book 3 of Ysabel the Summoner takes place underwater. This series is a YA fantasy, so the more fantastical the creatures, the better.

Enter the hammerhead, prowler of the deep.

Who, me?

Sweeping their popeyes back and forth gives them a panoramic view. They detect electrical impulses given off by prey hiding in the dark and under the sand.

What was that?

I hope never to see this coming at me.

Or looking up at this.

Next are Japanese spider crabs, aka tall-footed crab. My girl is going to meet some scary creatures.

Manta rays, the giant kind

My undersea adventures continue. I’m looking for companions for Ysabel when she’s underwater with the mermaids in book three of Ysabel the Summoner.

First up, giant manta rays!manta swimming2

These fabulous beasts swim gracefully through temperate ocean waters all over the world. They can grow up to 30 ft. wide and can weigh almost 3,000 lbs.

mantas feeding2

They feed on plankton, opening their long mouths wide (please don’t eat me) to funnel in plankton-rich seawater. Gill rakers, thin cartilage filaments in their mouths filter plankton from seawater.

They can leap completely out of the water. No one knows why; maybe as play, or a courtship display (big and fit!) or to communicate with their kind; the splash of their reentry can be heard for miles.


Swimming with mantas is popular with divers. But no touching, as apparently this disturbs the mucus that coats their skin and protects them against bacteria and microorganisms.


They’re vulnerable to becoming entangled in fishing lines and nets, and are hunted for their gill rakers as an ingredient in Chinese medicine.

These huge, gentle fish are unable to live in captivity. The biggest aquariums do not have sufficiently large pools. If captured, mantas refuse to eat and die within days.

They seem so sensitive; Ysabel may have to admire them from afar.

Leafies and Weedies

Under the sea, tra-la. My mermaid worldbuilding for book three of Ysabel the Summoner takes me, yes, under the sea. I’ve discovered bioluminiscent fish and jellies, giant clams and blue-eyed scallops. Today I found these wonderful little creatures. Seadragons are related to seahorses and grow up to 18 inches long. The leaf-like protrusions provide camouflage by making them look floating seaweed.

Weedy Sea Dragon2 The Weedy Seadragon, aka, a “weedie”.

Best camouflage ever.


Giant clams and many-eyed scallops

Book Two of the Ysabel the Summoner series is in the capable hands of my editor. On to book three. In this third book, my girl Ysabel is under the sea with the mermaids, recovering from a terribly injury.

Bioluminiscent fish and jellies light up her underwater world. Strange creatures abound.


Scallops! With blue eyes! The eyes are functional; they track movement and light. If the scallop loses an eye, another grows in its place.



Up close, they look like blueberries.


Giant clams, yikes! They giant clamgrow up to 4 feet across and have an average lifespan of 100 years in the wild. Before I started researching, I only knew them from comics and the covers of cheesy paperbacks, showing a clam closed tight around the leg of an unfortunate diver.



Like this.



It’s a myth, though. Giant clams are not fast moving; a diver would have to hang around for a long time with his leg jammed between the clam shells waiting for the two halves to sloooowly close.


I love research.

In the deep

My next book of Ysabel the Summoner is set deep underwater in the realm of mermaids. Their dark world is lit by bioluminescent creatures.

The jellyfish can be gorgeous:

This is a siphonophore, a colony of hundreds of jellies living along a central core. The fireworks display are the toxic, bioluminiscent tentacles used to lure and snare prey.



Abralia veranyl looks like an art deco brooch.







There also are scary creatures with gigantic eyes and fanged mouths, opened wide to suck in any passing prey.

And its friend, the Pacific viperfish.
