The dark, cold depths of the ocean surround Selkie as she glides through the inky blackness. Her massive form cuts effortlessly through the water, the occasional bioluminescent creature casting an eerie glow along her furry leopard seal tail. The anchor at the end of her tail drags along the seafloor, stirring up clouds of silt.

Selkie's keen eyes scan the darkness for any sign of prey. Her nostrils flare, catching the faint scent of blood in the water. With a powerful flick of her tail, she propels herself towards the source, leaving a trail of bubbles in her wake.

As she draws closer, Selkie can make out the silhouette of a shark, its fins cutting through the water as it struggles against an invisible assailant. A satisfied grin spreads across Selkie's face, revealing her sharp leopard seal teeth. She has found her dinner.

Selkie approaches the shark stealthily, her dark fur blending seamlessly with the shadows. In one swift motion, she clamps her powerful jaws down on the shark's thrashing tail, crushing it with ease. The shark thrashes violently, but Selkie holds firm, her strong muscles rippling under her scarred skin.

With a final, mighty tug, Selkie tears the shark's tail clean off, sending a spray of blood and flesh into the water. The shark's struggles grow weaker as Selkie begins to devour it alive, tearing into its flesh with gusto. Chunks of shark meat fly from her mouth as she feeds, the crimson blood staining her dark fur a deep, rusty red.

As Selkie feasts on the still-thrashing shark, she notices movement in the distance. Her keen senses pick up the faint sound of splashing, drawing her attention away from her meal. With a low growl, she releases the shark's carcass and swims towards the disturbance, her massive form cutting through the water with purpose.

As Selkie draws closer to the source of the splashing, she emerges into the dim light filtering down from the surface. The water here is clearer, and Selkie can make out the silhouette of another mermaid swimming nearby. This one is much smaller than Selkie, barely reaching half her size. Her dark eyes narrow as she takes in the sight of the smaller mermaid. Her lips curl into a predatory smile, revealing her sharp teeth once more. This newcomer could make for an interesting distraction from her hunt.

With a powerful stroke of her tail, Selkie closes the distance between them, her massive form looming over the smaller mermaid. She lets out a low, rumbling growl, the sound vibrating through the water and causing small fish to scatter in fear.

"Well, well," Selkie rumbles, her voice heavy with a thick Russian accent. "What do we have here? A lost little pup, out on her own in these treacherous waters?"

She circles the smaller mermaid slowly, her piercing gaze taking in every detail and her nostrils flare as she catches the delicious scent emanating from the smaller mermaid, a tantalizing aroma that sets her sharp teeth on edge.
