Quick answers
Do male seahorses really become pregnant?
Yes. The female deposits eggs in the male brood pouch; he incubates them. Linnaeus named Hippocampus in 1758; CITES Appendix II (2002) frames modern pressure.
What is Project Seahorse?
A conservation-research group led by Amanda Vincent that supplied much of the CITES and bycatch evidence from the 1990s onward.
Why CITES Appendix II in 2002?
Documented international trade in dried and live animals met a genus that is sparse, site-faithful and easy to over-collect.
Is the aquarium trade the main take?
By volume, dried medicine and curio shipments plus trawl bycatch outweigh hobby live fish in most analyses.
Can seahorses be farmed out of the problem?
Some live-hobby demand is captive-bred. Dried-trade volume and trawl bycatch are not solved by a hatchery SKU.
Why are they so slow?
A rigid bony plate body and a dorsal fin that buzzes rather than a caudal fluke. Camouflage replaces flight.

- 3 Natal or breeding site — A redd, eyrie, den, anemone or ice lair -- often a single-point risk (Izumi, Natron, Gir).

Every seahorse is a stack of tissues that must agree under season, prey and human pressure.
Meters below repeat the six atlas scores as gauges; they are relative marks, not laboratory certificates.
Systems
Support and integument
Bony rings, a tubular snout and a prehensile tail. There is no caudal fin to flee with -- the dorsal fin is a hover engine.
Feeding apparatus
Ambush of tiny crustaceans sucked through the snout. Male pregnancy is an energy and osmoregulatory job, not a metaphor. The feeding kit sets the ecological-role score relative to the other 23 types.
Respiration and circulation
Gas exchange and blood flow are tuned to the seahorse energy budget -- dive, hover, sprint or bulk browse -- not to a generic vertebrate template.
Senses and neural control
Independent eye turrets and sit-and-wait camouflage. Speed is not the sense that pays.
Reproduction and ontogeny
Replacement rate is the hidden resilience number. Site fidelity plus a dried price. Meadows and trawls set the ceiling.
Thermoregulation and salt/water
Climate and osmoregulation bound where a seahorse can close its daily budget. Field sites in the English-speaking world still measure that envelope first.
Relative meters
Hotspots
Primary weapon or tool
The bill, teeth, trunk, pouch or talon that field guides name first -- and that trade or conflict usually targets.
Energy store
Fat, cache, crop or bamboo hours that decide whether a season closes.
Natal or breeding site
A redd, eyrie, den, anemone or ice lair -- often a single-point risk (Izumi, Natron, Gir).
Sensory organ
Independent eye turrets and sit-and-wait camouflage. Speed is not the sense that pays.
Human interface
Hunt, tourism, film or quota -- the surface where seahorse biology meets English-language law.
Tissues & materials
Keratin and integument
Feathers, fur, baleen or skin plates -- tissues, not metals. Moult and wear are the maintenance cycle.
Bone and cartilage
Load paths for stoop, lunge, knuckle-walk or hover. Marrow and pneumatic bone differ by family.
Muscle and tendon
The expensive tissue that speed and intelligence scores only hint at.
Fat, oil and glycogen
Stores that migration, fast and lactation spend. A market for those stores (oil, ivory, fin) is a historical threat.
