The photo shows a Giant Clam (Tridacna gigas) spawning. We've seen clams spawning many times, always in summer and always in the mid to late afternoon. This clam was photographed just before sunset one day last summer at Kevin's Reef, a few nautical miles east of Lizard Island. The clam gently moves its valves a few times then suddenly draws them together and a massive stream of spawn is expelled through the excurrent siphon. The process is repeated several times by the same individual at 10 to 20 minute intervals
