Pygmy seahorses are miniaturised Hippocampus noted for extreme crypsis and male brooding; many live on gorgonians.
The pygmy seahorse, measuring about one centimeter in length, is also known as the dwarf seahorse. Its observed body colors include red, gray, yellow, and white, and it varies depending on the soft corals it inhabits. Different species may also exhibit mimicry based on their specific host corals, but all three species share the same "super-mini" size, with a maximum length not exceeding three centimeters. This tiny marine creature, which is not commercially viable, has driven the growth of the tourism market, making the pygmy seahorse craze in the diving tourism industry a remarkable phenomenon.
