Pygmy Sea horse and Seafan by Caro Lara on Prezi
I really cant live without a Seafan,as it provides me protection from predators. I have the ability to match the bright colors and texture of the. NO ONE knew that pygmy seahorses existed until marine biologist George Bargibant came across one by accident. He was studying sea fans. In recent years, six other new pygmy seahorse species have been .. ).

Diving with Seahorses
Abstract An overview of the octocoral and hydrozoan host species of pygmy seahorses is provided based on literature records and recently collected field data for Hippocampus bargibanti, Hippocampus denise and Hippocampus pontohi. Seven new associations are recognized and an overview of the so far documented host species is given. A detailed re-examination of octocoral type material and a review of the taxonomic history of the alcyonacean genera Annella Subergorgiidae and Muricella Acanthogorgiidae are included as baseline for future revisions.

The host specificity and colour morphs of pygmy seahorses are discussed, as well as the reliability of previous identifications and conservation issues. Syngnathidae are diminutive tropical fish that live in close association with octocorals, colonial hydrozoans, bryozoans, sea grass and algae Lourie and Kuiterbut little information is available about their host specificity.
Distribution They are found all over the world and inhabit coral reefs and sea grass beds. They have been recorded at depths as low as 0.
The Barbigants pygmy seahorse hippocampus barbiganti can be found all over Indonesia in various colours and at all depths. These fans have bulbous red polyps as do the pygmies.
This, along with their small size, is what makes them so difficult to spot.
Denise Hackett recently discovered a new pygmy species in Indonesia. It's named after her, Hippocampus Denise, but it's often called the 'plucked chicken pygmy seahorse' due to its unusual appearance with a lack of the typical bumps tubercles. Hippocampus Denise is normally found in light yellow gorgonians which, like the pygmy, are less bulbous with smaller polyps. The weedy pygmy seahorse is an even newer discovery. First recorded in the Banda Sea inthey are now regularly seen at Wakatobi and the Lembeh Strait.

The Raja Ampat area is another good place to find them. This species is the smallest and most cryptic. They seem to move around more than other species making them even harder to pin point. Ecological Considerations Pygmy and common seahorses such as the tigertail, are sensitive to stress and too much harassment from divers is certainly not good for them.
They particularly dislike bright lights and will turn their heads away if a diver shines a dive light at them.Tulamben : how to destroy pygmy seahorses
Placing a red filter or red plastic bag with an elastic band over it on to a dive light will give a softer diffused light that they will be less sensitive to and should enable photographers to get better pictures.
Threats Their numbers around the world are diminishing. Dried seahorses are viewed as a cure for a range of conditions such as asthma and skin disease, but they are most commonly used as a treatment of sexual dysfunction.
Asian nations consume around 45 tons of dried sea horse annually. That's equates to about 16 million of them! One problem is that many of the harvested seahorses are juveniles and have not had a chance to breed and reproduce. There is no clinical proof that they have any medicinal benefits but the Chinese have been using them as a fundamental part of their traditional medicine for centuries and there is a strong conviction that there is a benefit.
They are also being over-collected for the aquarium trade in Europe, North America and Japan.
Furthermore, their habitat is under threat. Sea grass areas, mangroves and coral reefs are declining world wide. Some seahorses, such as the big-belly seahorse is on the precipice between vulnerable and endangered. Many others have not yet been categorised due to lack of data.
Fortunately some more progressive nations do have unilateral protective measures in place. The trunk is round but thin when viewed from behind. They are seen in high-current areas at depths of m.
This is a free-living species that is found near coral walls with soft corals. They are nocturnal and very active at night. They have been found in only a few places in Indonesia and northern Borneo.
They can be brown to pale with specific markings such as a dark spot in front of each relatively large eye. Both males and females have a round trunk. They are found from 15 — 20 meters deep in groups of 3 to 5.
They are almost the same shape as Pontoh's pygmy seahorse, but are a different colour: They can be found on any part of the reef, but often on hydroids and algal turf in pairs or small group.
They are no larger than 1. The soft coral have fat stems and this seahorse has a correspondingly long tail. They vary from pale pink to yellow. It has a very small range: However, there are unconfirmed reports from eastern Papua New Guinea and Taiwan. It was described in
