Diodon holocanthus, known commonly as the longspined porcupinefish or freckled porcupinefish among other vernacular names, is a species of marine fish in the family Diodontidae.[2]
Diet
The species' diet includes sea urchins and hard-shelled mollusks.[3]
Distribution
The Longspined porcupinefish has a circumtropical in distribution, being found in the tropical zones of major seas and oceans:
- In the Atlantic it is found from Florida and the Bahamas to Brazil and in the Eastern Atlantic from 30°N to 23°S, as well as around South Africa.
- And In the western Indian Ocean from the southern Red Sea to Madagascar, Réunion and Mauritius.
- Also In the Pacific Ocean from southern Japan to Lord Howe Island, and east to the Hawaiian and Easter islands. Also from southern California to Colombia and the Galapagos Islands.[4]
Description
Pale in colour with large black blotches and smaller black spots, these spots becoming fewer in number with age. Has many long, two-rooted depressible spines particularly on its head. The teeth of the two jaws are fused into a parrot-like "beak". Adults may reach 50 cm (20 in) in length.[5] The only other fish with which it might be confused is the black-blotched porcupinefish, (Diodon liturosus) but it has much longer spines than that species.[6]
Diet
An Omnivore that Feeds on mollusks (molluscs), sea urchins, hermit crabs, snails,herbivor diet and crabs during its active phase at night.[7] They use the beak combined with plates on the roof of the mouth to crush their prey such as molluscs and sea urchins that would otherwise be indigestible.[8]
Habitat
They are found over the muddy sea bottom, in estuaries, in lagoons or on coral and rocky reefs around the world in tropical and subtropical seas.[9]
Spawning
Spawns at the surface at dawn or at dusk in pairs or in groups of males with a single female; the juveniles remain pelagic until they are at least 7 cm (3 in) long.[5] Young and sub-adult fish sometimes occur in groups.
Uses
It is used in Chinese medicine,[citation needed] and is captured at the surface with a hand net.[citation needed] It is poisonous if not prepared correctly.
