Very special thanks for this unique photo of Hippocampus paradoxus to Ralph Foster and Thea Williams from the South Australian Museum.
"The Paradoxical Seahorse, Hippocampus paradoxus, is a recently described species from the Great Australian Bight (Foster and Gomon, 2010). Known only from a single specimen collected in 1995, this small species breaks the planning rules of seahorse anatomy. It is the only known seahorse without a dorsal fin, instead having a series of fleshy lobes down the back and tail. It also lacks the rigid external bony plates that characterise most seahorses. The numbers of plates ringing the body and tail of a seahorse are key taxonomic (identification) features but were very difficult to determine in the specimen because of the fleshy dermis. To visualise the remnants of the rings and other features hidden beneath the skin, South Australian Museum researchers turned to micro-CT scanning. The technique proved to be remarkably useful allowing detailed, non-destructive examination of not only the skeleton but some soft tissue features, as well, such as unlaid eggs in the abdomen. Some of the CT scan images used to scientifically describe Hippocampus paradoxus are presented here, along with CT scans of two other seahorse species, H. breviceps and H. denise, for comparison. - See more at: http://www.samuseum.sa.gov.au/research/biological-sciences/fish/1098#sthash.Lthecy39.dpuf"

Feeding intake.
The fish take a long time to eat at the beginning, before the food is taken up, a close inspection is carried out. After acclimatisation, the offered frozen food is eaten without problems. It should be noted that wild-caught fish behave differently than offspring when it comes to food intake. In the case of offspring, the size of the fish purchased also plays a role in the choice of food.
