What ocean animals are included?

Sharks, rays, whales, dolphins, seals, sea turtles, octopuses, squid, cuttlefish, nautilus, jellyfish, reef fish, deep-sea fish, crustaceans, sea stars, sea urchins, corals, and sponges. All four taxonomic classes that have ocean-dwelling species are represented.

Are deep-sea animals included?

Yes. Coelacanth, oarfish, colossal squid, anglerfish, and others are in the database — many flagged as Hard difficulty for the Game mode.

Can I filter to just sharks?

Use the Filters panel — pick Class: Fish + Diet: Carnivore for shark-like results. Or open the Filter panel and search for shark-named species.

Why are some sea animals not "fish"?

Whales, dolphins, and seals are mammals, not fish. Sea turtles are reptiles. Octopuses and jellyfish are invertebrates. The taxonomic class on every card shows you exactly what biological group each animal belongs to.

Are coral reefs covered?

Yes. Coral, sea anemones, and reef-dwelling fish like clownfish, blue tang, and parrotfish are included. Corals are critically endangered and carry the appropriate badge.

What it does

Pre-filtered to ocean habitat

Habitat is locked to Ocean. Every Generate click returns a real marine animal — finned, shelled, tentacled, or scaled.

Cross-class coverage

Mammals (dolphins, whales, seals), fish (sharks, reef fish, deep-sea fish), reptiles (sea turtles, sea snakes), and invertebrates (octopuses, jellyfish, crustaceans, corals) all included.

Conservation focus

Many ocean species are threatened. Each card carries the IUCN-style status — apply the Endangered preset to focus on species worth protecting.

Writing-prompt ready

Ocean settings work beautifully with the Mysterious tone preset. Try "A leatherback turtle in the foyer of a hotel that wasn’t there yesterday, following a trail of footprints that suddenly stop."

When to use this

Marine biology class

A high-school teacher generates 15 random ocean creatures and asks students to research each one’s threats. The Conservation badge gives an instant priority order.

Aquarium visit prep

A parent generates 10 random ocean animals before a trip to the aquarium so the kids have something to look out for — turning the visit into a scavenger hunt.

Underwater story prompt

A novelist switches to Writing Prompt mode with the Mysterious tone — gets "A nautilus on the deck of a creaking pirate ship, replaying a memory that doesn’t feel like its own." Instant scene seed.
