Seahorse Species

About Seahorse Species

• Seahorses are marine fish.
• They belong to the family Syngnathidae, which also includes pipefishes and seadragons.
• They belong to the genus Hippocampus.
  • The name Hippocampus is derived from two Greek words: hippos, meaning ‘horse’, and kampos, meaning ‘sea monster’.
• Habitat: Seahorses inhabit marine ecosystems, including seagrass beds, mangroves, coral reefs and estuaries.
• Key Features of Seahorses
  • Body Structure: Seahorses have a horse-shaped head, an upright body and a curled tail that helps them grip marine vegetation.
  • Body Covering: They lack scales and have bony plates covering their bodies.
  • Camouflage: They can change colour and adjust their body spines to blend with their surroundings.
  • Reproduction: Males carry eggs in a pouch and give birth to live young, not females.
  • Ecological Role: They act as predators in seagrass beds, mangroves, coral reefs and estuaries.
• Threats: Bottom trawling and accidental capture in fishing nets threaten seahorses.
  • Illegal trade also puts pressure on their populations.
• Taxonomic Classification: The study identified three separate species:
  • Hippocampus histrix
    • Distribution: It is distributed in the Pacific Ocean.
    • IUCN Status: It is classified as Vulnerable.
  • Hippocampus jayakari
    • Distribution: It is found in the Arabian region.
    • Key Feature: It is a poorly known species.
    • Its distribution boundary with Hippocampus amandavincentae requires further investigation.
  • Hippocampus amandavincentae
    • Distribution: It is distributed in the Indian Ocean, with evidence of its presence in Madagascar, Mozambique and the Seychelles.
    • Key Features: It has a shorter snout, five spines on its crown and stronger spines along its trunk and tail.
      • Genetic analysis revealed a 6–7% difference from the Pacific species.
      • Its population remains unknown.
