Picture of the Week, Leafy Sea Dragon

6a79Leafy Sea Dragon Picture of the Week, Leafy Sea Dragon
There is something that is just so alluring about sea dragons. Although they aren’t too different from seahorses, usually moving in the same slow and methodical fashion while they cruise around the aquarium, they are far more elaborate in their appearance. Looking like an ultra modified versions of their close seahorse relatives, sea dragons are often adorned with elaborate fins that resemble marine vegetation like Sargassum, kelp, and whatever else is readily available in their habitat. And like seahorses, the sea dragons are just so cute and are super easy to photograph. They can get quite camera shy, but after warming up to us, we are usually able to get good pictures of them, such as the one shown above. The image was taken at the Aquarium of the Pacific in Long Beach, California. MORE: Picture of the Week, Leafy Sea DragonMore:

Hot Summer, Cool Seahorses: Cooling The Seahorse Aquarium

Hot Seahorses Desert Hot Summer, Cool Seahorses: Cooling The Seahorse Aquarium
Summer’s here, and seahorse aquarists are starting to see tank temperatures rise. Seahorses, are particularly vulnerable to warmer temperatures , so for many seahorse aquarists, even moderate heat can lead to a mad dash to lower the water temperature. The consequences of warm water can be deadly for seahorses. Bacteria spread at a faster rate in warmer water, so the warmer it gets, the more likely you are to see illness pop up in your aquarium. Another often overlooked problem is that warmer water holds less oxygen, stressing out the inhabitants of your aquarium. This tends to be worse for seahorses than other fish due to their lobed gill structure. Fans, your first line of defense Often, open tops with fans blowing across the water is enough to drop temp a few degrees. This works by evaporative cooling. Removing tops, and placing a fan so it blows across the water will make More: Hot Summer, Cool Seahorses: Cooling The Seahorse AquariumMore:

Video: Close-Up Time For Captive Bred Pygmy Seahorses

 As the newest (and unquestionably cutest) arrivals to the vast collection of marine life at San Fransisco’s Steinhart Aquarium, the baby Pygmy Seahorses Hippocampus bargibanti shown in this video are the progeny of a breeding pair that were collected in the Philippines in May of this year. Overseen by Steinhart Biologists Matt Wandell and Richard Ross, the babies have now moved on from their specially designed Kreisel system, and have settled on and adapted the colouration of their host Muricella genus Gorgonians. What a fantastic achievement! More detail at Advanced Aquarist More: Video: Close-Up Time For Captive Bred Pygmy SeahorsesMore:

How Ocean Rider Is Fighting to Save Seahorses

seahorse in hand Otávio Nogueira cc 1200x694 How Ocean Rider Is Fighting to Save Seahorses
Ocean Rider, as part of their Seahorse Hawaii Foundation efforts, announced late last year that it was going to be reintroducing seahorses back into the wild in a few locations. On the surface, this sounds like a great step towards conservation. Reintroduction programs are very popular with the public, and who wouldn’t want seahorses reestablished in the wild? Unfortunately, these types of reintroduction programs have limited success, and can actually do more harm than good. It is true that seahorses are at risk from overfishing. But they haven’t disappeared from the wild, making programs to reestablish them moot. Reintroduction programs are generally only beneficial in places that a species has been wiped out completely, and only when the conditions that caused their decline are reversed. Seahorses are still found all over the world, no single species lost from it’s native range. Nor are any critically endangered, for that matter. The sad truth is that the Seahorse Hawaii Foundation’s reintroduction program is ill-advised and unnecessary, and potentially harmful.

Grumpy Seahorses Growl When Goaded

giantbrazilian 300x225 Grumpy Seahorses Growl When GoadedAlthough they usually exude peacefulness and elegance, research recently published in the Journal of Zoology has revealed that Seahorses possess a distinctly more assertive side to their character, and can even emit a deep and angry ‘growl’ in certain situations.  Examining the acoustic behaviour of Hippocampus reidi (Long-snouted seahorses), the researchers used a specially sound-proofed aquarium, equipped with a hydrophone and video camera, to document the clicking sounds that the seahorses make during reproductive behaviour and when feeding. They were also surprised to discover however, the previously un-described growling noises which were made when the seahorses were under stress, such as when they were being handled. Interestingly, the relatively low frequency growl was also accompanied by a vibration of the seahorse’s body and it is thought that the reaction may be an escape mechanism produced to startle predators. More: Grumpy Seahorses Growl When GoadedMore:
