Summary
Whale-fall ecosystems support an abundance of life in waves of successive communities. The carrion of the whale is first stripped of all its flesh by larger scavengers. Once all the flesh is gone, and any debris in the sediment has been hoovered up by opportunists, bacteria break down the bone lipids to produce energy that supports an ecosystem of life around the carcass...
Superman, secret journalist, champion of Metropolis and defender of the sea, does his best to protect any and all life in the open ocean. After his first ever loss, Clark sinks into the abyss and meets the creatures of the deep.

Summary
Where in,
Bruce, who to the honor of his late father took to being a renouned doctor founding many hospitals and clinics, receeds into obscurity after the death of his last close family member, a butler who raised him after the death of his parents. Months later finds Bruce on a beach house in a small island town somewhere in the europes. He stays far from the small town, only ever venturing for food and such, and lives on his private beach. He often takes his boat out to open ocean and spends hours watching the waves and sketching. It here he sees his first glimps of them.
A mermaid springs from the water, splattering droplets as his breaks the surface tension, and lands smack in bruces little yacht. Only, it looks more like a lad then a maiden and more like child then either and oh fuck, he choking on fishing net.
Or where Bruce wishes the universe, and the lovely ghost of his parents, would very kindly stop dropping ocean children on his front door and the secrets of his beach that he was not curious about at his back door. They make no plans to listen to his silly lil request.

Summary
Steph had done this before. She knew the risks, she knew the dangers, and she could get herself out. It was under control. It was fine. She didn’t need Tim’s help. She definitely didn't need help from Bruce.
Steph falls overboard in the middle of sabotaging her father's ship, the Cluemaster. She wakes up on a raft, saved by Cass: a mermaid she'd never met before, but who seems to know a lot of her friends. The two of them have to get back to Bruce's boat, and they might fall for each other a little bit along the way.

Summary
As he finishes sanding off the sides, Bruce is fairly certain that most parents have never built a boat with their youngest as a form of father-son bonding time with the end goal of having it sunk by his four mer children and their two mer friends as enrichment. However, when Clark puts the boat on the surface of the tank and the mers all swim up to investigate it, Bruce thinks that they should.
Or sometimes being a good parent involves accidentally training your mer children in the most efficient ways to destroy boats.
