Denise's pygmy seahorse uses adaptive camouflage, changing its color to match that of the surrounding gorgonians. [4] It feeds on small crustaceans and other zooplankton. [6] An individual will stay on a single coral for the duration of its entire life. The species is ovoviviparous, and it is the male who broods the eggs in its ventral brood pouch.
Denise's pygmy seahorse (Hippocampus denise) was described in 2003. Its range is from Borneo to New Guinea, Solomon Islands and Palau. They must live on gorgonian corals but have been found on eight different genera: Acanthogorgia, Annella, Echinogorgia, Ellisella, Melithaea, Muricella, Verrucella and Villogorgia. Each pygmy seahorse stays on ...
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.
Because pygmy seahorses are so small — about 1 inch (2.5 centimeters) long — divers tend to photograph them in extreme close-ups, which include detailed views of nearby corals. On iNaturalist ...
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]
Pipefish look like straight-bodied seahorses with tiny mouths. The name is derived from the peculiar form of the snout, which is like a long tube, ending in a narrow and small mouth which opens upwards and is toothless. The body and tail are long, thin, and snake-like. They each have a highly modified skeleton formed into armored plating. This ...
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.
