Scary 'sparks' in the ocean

Fire urchins, also known as red urchins, have the scientific name Fire sea urchin, they are small "sparks" and a scary "immeasurable" assassin in the deep ocean.

Fire porcupines are found in many areas of marine biodiversity, the Indian Ocean and the Pacific Ocean. It was discovered and described and in 1778, by German biologist Gottfried Nathaniel Leskel.

Fire porcupines have a basketball size with an average diameter of 18 - 20cm. The whole of the fire urchin grew spiked with short, long spines, and scattered like a regular V-shaped. The groove divides thorny branches decorated with a series of "beaded" beads blinking with iridescent blue light. The whole body was glowing with fire and glowing with extremely eye-catching colors like pink, red, blue, brown .

Fire porcupines usually live at a depth of 10-30m, a maximum of 70m. Living range from the African coast to the waters of Hawaii and Australia. They are present in the lagoon, the bay, where there are sand, small pebbles or corals. Fire porcupines live in groups of up to several dozen or even hundreds.

The favorite food of this species is seaweed, small fish and other creatures. They often use glowing and brilliant colors at night to attract prey. Thorns seem harmless, but contain human venom. Their venom paralyzes and kills a sea turtle, even humans if they accidentally step on them.

The fire urchins quietly lie still in place like a benign, harmless flower, but when the prey comes close, they use all the tentacles to release venom until the prey is stiff. They used sharp teeth to tear apart and leisurely enjoy their prey.

Adult fire urchins will release eggs and sperm into the water to perform the breeding process. Eggs are fertilized in the external environment and develop into larvae. A fire urchin spawns thousands of small eggs each time. However, not many eggs become larvae and grow into juveniles. The porcupine egg is floating in the water and is a lucrative bait for small fish and many other creatures in the ocean.
