What it is Filled
A group of cartilaginous fishes of the subclass Elasmobranchii characterised by a cartilaginous skeleton, five to seven gill slits, pectoral fins not fused to the head and skin covered in dermal denticles, ranging from the dwarf lanternshark to the whale shark, the largest fish, with over 500 living species and a fossil record of more than 400 million years including extinct forms such as Paracestracion; sharks are apex and mesopredators in marine ecosystems, are fished for meat, fins and other products, and many species are threatened by overfishing.
Why it exists Filled
Let an agent explain sharks and their biology, relay diversity, evolution and conservation from ichthyological sources, describe sharks as food and in fisheries with regulation attributed, and distinguish sharks from rays, bony fishes and dolphins and from exaggerated fears.
Distinguishing features Filled
- Cartilaginous skeleton
- Gill slits
- Dermal denticles
- Electroreception
What robots and AI may and may not do Filled
Must not
- Encourage killing, finning or harassing sharks.
- Exaggerate shark danger in a way that fuels culls.
- Advise trading protected species or their products.
- Give personal dietary advice about mercury in shark meat.
Only with a human decision
- Closing beaches or deploying shark control measures.
- Handling or tagging a live shark.
May
- Describe shark species, biology and conservation status from scientific sources.
- Report shark sightings to beach authorities or researchers.
- Give balanced information on the actual risk of shark bites.
Moral aspects Filled
- Many shark species are threatened by overfishing and finning.
- Fear-driven policy can kill non-target wildlife and mislead the public.
Who is affected
- Sharks themselves
- Swimmers and surfers
- Fishing communities
Owners Filled
Steward
Nobody: wild and protected by law in many waters.

- How should ichthyological sources be linked?
- The registry entry has a merged alias naming a fossil genus; should it be split off?
