The evolution of seahorses from pipefish may have been an adaptation related to the biomechanics of prey capture. The unique posture of the seahorse allows them to capture small shrimps at larger distances than the pipefish is capable of.
Although some species have become extinct, the major stages of evolution are still represented in living species. The timing of only two evolutionary events is known with some certainty: the evolution of the first pipefishes and the evolution of seahorses. The placement of the pipefish-like pygmy pipehorses has yet to be confirmed by genetic data.
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 Syngnathiformes / ˈ s ɪ ŋ (ɡ) n ə θ ɪ f ɔːr m iː z / are an order of ray-finned fishes that includes the leafy seadragons, sea moths, trumpetfishes and seahorses, among others. [2] These fishes have generally elongate, narrow bodies surrounded by a series of bony rings, with small, tubular mouths.
Gestation lasts a few weeks, then males will release the eggs without caring for them. Generally, males are ready to breed again almost immediately after giving birth. Though little is known about the great seahorse's specific breeding habits, many related seahorses have been studied and were found to occasionally be monogamous.
As many as 250 babies can be released during the delivery.
Photographs of seahorses taken by scuba divers revealed evidence of a long-lost species of marine worm that hasn’t been seen since the mid-1950s, scientists say. Long-lost ocean worms photobomb ...
The lined seahorse (Hippocampus erectus), northern seahorse or spotted seahorse, is a species of fish that belongs to the family Syngnathidae. [ 3 ] [ 4 ] H. erectus is a diurnal species with an approximate length of 15 cm (5.9 inches) and lifespan of one to four years.
