Smallest Known Seahorse - Satomi's Pygmy Seahorse
One of the most interesting new species from the State of Observed Species Report is this miniature seahorse - Satomi's Pygmy Seahorse - with a biological name of Hippocampus satomiae. It is only about 0.54 inch in total length. When swimming and with its tail curved it is only about 0.45 inch high!
This tiny animal was discovered near Derawan Island off Kalimantan, Indonesia and first described scientifically in 2008. The name "satomiae" was given to recognize Miss Satomi Onishi, the diving guide who collected the type specimens.
