The weedy pygmy seahorse is a small fish which can reach a maximum length of approximately 1.7 cm, which makes it one of the smallest representatives of the seahorses. [4] The body is small and slender with a prehensile tail. The head is relatively large, it represents about 25% of the size of the body. [4] The eyes are prominent.
Severn's pygmy seahorse (Hippocampus severnsi) is a free-living species described in 2008. They are almost the same shape as Pontoh's pygmy seahorse, but are a different colour: pale brown with red and orange patches. They can be found on any part of the reef, but often on hydroids and algal turf in pairs or small group.
Pygmy seahorses have a single gill opening on the back of the head (instead of two on the sides as in normal seahorses), and the males brood their young inside their trunk, instead of in a pouch on the tail. [11] A molecular phylogeny confirms that the pygmy seahorses are a monophyletic sister lineage of all other seahorses. [10]
Pygmy seahorses, about the size of a fingernail, are some of the smallest vertebrates in the world. First discovered in 1969, little was known about the creatures. But in the early 2000s, British ...
Hippocampus bargibanti, also known as Bargibant's seahorse or the pygmy seahorse, is a seahorse of the family Syngnathidae found in the central Indo-Pacific area. [3]This pygmy seahorse is tiny—usually less than 2 centimetres (0.79 in) in size—and lives exclusively on gorgonian sea-fans, as its coloration and physical features expertly mimic the coral for camouflage.

Seahorse life-cycle. The male seahorse is equipped with a brood pouch on the ventral, or front-facing, side of the tail. When mating, the female seahorse deposits up to 1,500 eggs in the male's pouch. The male carries the eggs for 9 to 45 days until the seahorses emerge fully developed, but very small. The young are then released into the water ...
Comprising over 160,000 described species, the Lepidoptera possess variations of the basic body structure which has evolved to gain advantages in adaptation and distribution. [1] Lepidopterans undergo complete metamorphosis, going through a four-stage life cycle: egg, larva or caterpillar, pupa or chrysalis, and imago (plural: imagines) / adult
Male seahorses have a specialized ventral brood pouch to carry the embryos, male sea dragons attach the eggs to their tails, and male pipefish may do either, depending on their species. [4] The most fundamental difference between the different lineages of the family Syngnathidae is the location of male brood pouch. [ 5 ]
