For the first , scientists have unlocked the  to one of the world's  recognizable and unique, but least understood fish – the seahorse. Researchers have worked out the  code of the Southeast Asian tiger tail seahorse. They now have the genetic  of all of its DNA. This means scientists can find out a lot  about this sea  than before. They can now start to figure out why seahorses are so different to other fish. Unlike other fish, seahorses have no . Another difference is the male brooding of their  - male seahorses carry babies and give birth to them instead of females. In addition, seahorses do not swim horizontally like other fish; they swim  (up and down).
Scientists from Germany’s University of Konstanz and  from China and Singapore helped to sequence the genome of the tiger tail seahorse. A  is a map of all the genes and genetic  in a cell or organism. Seahorses started to change from other fish about 100 million years . They began to take on their  shape, which resembles a horse. There is a total of 54  of seahorse. Its scientific name is Hippocampus. The word 'Hippocampus' comes from the Ancient Greek word hippos meaning 'horse' and kampos meaning 'sea monster'. The  'seahorse' can also be written as two  words (sea horse), or hyphenated with a  between the  words (sea-horse).
