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.

Females have a slender body with a small bulge at the base of the trunk, while males are rounder. They are found at depths of 13–90m. Underwater photographer Denise Tackett noticed that they were different from H. bargibanti and brought them to the attention of scientists. [10] Pontoh's pygmy seahorse (Hippocampus pontohi) was named in 2008 ...
The short-snouted seahorse (Hippocampus hippocampus) is a species of seahorse in the family Syngnathidae.It is endemic to the Mediterranean Sea and parts of the North Atlantic, particularly around Italy and the Canary Islands.
The subfamily Hippocampinae is named after the seahorse genus Hippocampus, which is derived from the Ancient Greek ἱππόκαμπος (hippokampos), a compound of ἵππος, "horse" and κάμπος, "sea monster". The morphologically intermediate nature of pygmy pipehorses is reflected in the name "pipehorse", a combination of the first ...

One example of this convergent evolution arises in pygmy seahorses (Hippocampus bargibanti, Hippocampus denise, Hippocampus pontohi). Pygmy seahorses are very small (about 1–2 cm tall) trunk brooders, phylogenetically surrounded by tail brooders. It's likely that the pygmy seahorse once had their brood pouch on their tail.
The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse'), also hippocampus proper, is a major component of the brain of humans and many other vertebrates. In the human brain the hippocampus, the dentate gyrus, and the subiculum are the components of the hippocampal formation located in the limbic system.
The dentate gyrus (DG) is part of the hippocampal formation in the temporal lobe of the brain, which also includes the hippocampus and the subiculum.The dentate gyrus is part of the hippocampal trisynaptic circuit and is thought to contribute to the formation of new episodic memories, [1] [2] the spontaneous exploration of novel environments [2] and other functions.
