Photo: Demure seahorse plays coy in the coral

Our photo of the day comes from the waters off Sydney, Australia.

The family to which seahorses belong, Syngnathidae, also includes seadragons, pipefishes, and pipehorses – what a wonderfully curious collection of creatures. There are at least 200 species in the family, and around 35 of those are seahorses.

The sweet little pony here, photographed by John Turnbull, is called a White's Seahorse (Hippocampus whitei). They are endemic to Australia, and they are as charming as ever.
