Not Dwarf Seahorses, Baby Seahorses

It came to my attention recently that sometimes very young juveniles of larger seahorse species are being sold as Dwarf Seahorses Hippocampus zosterae due to the exceptionally small size they are being sold at. This issue came to light by way of the our forum member Maryg. She asked to confirm the species of a couple seahorses sold through her local fish store as dwarf seahorses. The seahorses in question were in fact juvenile Tiger Tail Seahorses Hippocampus comes

Boxing Clever: Engineers Draw Inspiration From Bulletproof Boxfish

Publishing their findings in the July 27 issue of the journal Acta Materialia, engineers at the University of California, San Diego have described how the body of the boxfish Lactoria cornuta could serve as inspiration for improved armour, robots and even flexible electronics. The boxfish joins other reef organisms such as seahorses and stomatopods being studied for such purposes. Drawing its strength from hexagon-shaped scales and the connections between them (similar to the connections in a baby’s skull) the boxfish’s body features a unique construction in which each scale, or scute, has a raised, star-like structure in the centre that distributes stress across the entire surface. In addition, there is an underlying, flexible layer of interlocking collagen fibre which is difficult to penetrate. In combination, this means that even if a predator managed to generate a crack in the outer layer, the collagen fibres would help to prevent the structure from failing. “These damage-resisting structures have evolved for millions of years in nature and are being studied with support of the U.S.

Seahorse-Inspired Engineering

3-D printed seahorse tailA team of engineers at Clemson University, led by Michael M. Porter, have created a 3-D printed model of a seahorse’s tail in the hopes of finding out if the tail’s unique shape – an organization of square prisms surrounded by bony plates that are connected by joints – has a functional advantage over the cylindrical tails that most animals possess. After the scientists created 3-D models of a square prism and a cylindrical tail, they whacked the models with a rubber mallet and twisted and bent them. The findings?  The square was stiffer and more resilient when crushed, and was half as able to twist, a feature which could help prevent damage and supply greater control.… More:

Photo by Louise Hines In Frozen Mysis Part 1: The Quest For Quality Mysis, we took a look at how to best select quality mysis for our seahorses, and what to avoid. In this long overdue part two, we’re going to take a look at why being picky about our frozen food matters. Just What Does Freezing Do

 Syngnathid fish fans have a new species to fawn over, according to a recent article in Scientific American Magazine. Until now, only two species of seadragon were known, the leafy and weedy seadragons. No new seadragon species has been discovered in 150 years. This newest addition to the small group, the aptly-named ruby seadragon, was uncovered by a trawler during a routine biodiversity survey by the University of Western Australia’s Marine Futures project in 2007. It was a happy surprise indeed. It is not only a very strange and attractive animal, but is decidedly quite… More:

Weedy Seadragons Available to Hobbyists

reefs.comSeadragonColdwater Marine Aquatics is bringing in captive raised weedy seadragons (Phyllipteryx taeniolatus) available to the masses. For me this news is akin to the first time I heard Borbonius anthias coming into the industry after drooling over their pictures for years. I had the pleasure of meeting the C.M.A. crew at MACNA Denver last year. I can tell you that these guys are incredibly knowledgeable regarding their niche in the industry, seemingly offering only the healthiest animals all around. I asked C.M.A. regarding the rearing technique and they replied with, “Berried adult males are collected annually and the young are hatched out and raised in captivity.”… More:

How To Pick Your First Seahorse: 12 Common Seahorse Species Explored

Any number of species of seahorses can be suitable for the right aquarium. Left to right: Hippocampus erectus, Hippocampus barbouri, Hippocampus reidi I’m often asked which species of seahorse aquarists should get for their first aquarium. This question may sound simple enough, but different species behave differently and have varying levels of care required. I’ve put together a list of the most commonly available species, their difficulty level and some additional notes.
