Could a camera flash hurt a seahorse?
Seahorses do not have any special lighting requirements other than the fact that most species prefer low to moderate light levels rather than bright light. Most animals get distressed by repeated flashes, just do it to a dog, they turn away after realising what it is. People are so insensitive, at least they weren’t banging the sides of the tank like some people I’ve seen. edit: They are not blind: “Seahorses’ eyes are able to move independently looking out for food and predators at the same time. They are ambush predators, lying in wait for small fish and shrimps to come within range. They suck food in through their trumpet-like snouts and swallow it whole as they have no teeth.” – Seahorse Conservation, Anglesea Sea Zoo Centre, Wales.
