Seahorses are a group of 47 small marine fish species from the genus Hippocampus. They have a head and neck similar to that of a horse, a body composed of segregated bony armour, straight carriage and entwined prehensile tail, devoid of any teeth and stomach. They usually swim in pairs and evade their predators by personating the colour of submerged plants. One unique feature of seahorses is that the male takes up the eggs from females into their forward-facing pouch and later on releases the youngs once they are mature. This allows the females to generate greater numbers of eggs resulting in fast reproduction. They are also monogamous. 

Sea horses are distributed mostly in the shallow tropical and temperate saltwater worldwide. Their common habitats include areas such as estuaries, coral reefs, seagrass beds and mangroves.

There are many reasons why seahorses are tumbling down in numbers. First and foremost, biological usage such as legal and illegal capture of the species for decorative exhibition such as souvenirs. Besides, significant numbers of the seahorses mostly juveniles are traded for aquariums. Likewise, over 20 million seahorses are estimated to be traded for the manufacturing of traditional Chinese medicine. 

Seahorses are often captured alongside other commercial fishing. Man-made activities such as pollution from domestic and urban wastewater, agriculture and forestry effluents are also harming the proper growth and reproduction of seahorses. Furthermore, deforestation leads to increased deposition in the surrounding marine water bodies leading to habitat degradation of seahorses.
