Long fascinated by anemones, I take photos of them on almost every dive. Other photographers look at me like I’m crazy (probably am, I admit), but I think they are incredibly beautiful. Anemones are close relatives to corals and jellies. They have stinging polyps and spend most of their time hanging out on coral reefs waiting to take in the next prey. “Their bodies are composed of an adhesive pedal disc, or foot, a cylindrical body, and an array of tentacles surrounding a central mouth. The tentacles are triggered by the slightest touch, firing a harpoon-like filament into their victim and injecting a paralyzing neurotoxin. The helpless prey is then guided into the mouth by the tentacles.” (http://animals.nationalgeographic.com/animals/invertebrates/sea-anemone/). I have seen them hitch rides on other creatures, and close up their body. You’ll often find crabs nearby, and anemone fish. There are over 1000 types of sea anemone, and obviously I have only seen a few, but take a look and see how lovely they are, and how deadly (but not to humans).
