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.
Best camouflage ever.
