The Longspine seahorse (Hippocampus histrix) is a saltwater fish of the family Syngnathidae that grows up to 17 cm.
Description
The thorny seahorse is a seahorse (Syngnathidae) from the Indo-West Pacific. The species is recognised by the sharp, thorn-like projections over its entire ring-armoured body and the long snout. With its prehensile tail it clings to weed, seagrass or coral on shallow sheltered reefs. With its tube-shaped snout it sucks up small zooplankton. The male carries the eggs in a brood pouch. It is considered vulnerable through trade and habitat loss.
