  3. 3. Underwater World ● Underwater World is extremely variable. Scientists discover new and new species of marine fish and animals continuously. There are over 30 000 species of fish and a lot of mollusks and crustaceans dwell on Earth.
  4. 4. Sea Urchins The sea urchins is one of the most beautiful marine animals. Sea urchins are small, spiny, globular animals. There are about 950 species of sea urchins inhabit all oceans from the intertidal wave to 5000 meters deep. The sea urchins, those are so visually arresting, dangerous for swimmers and sometimes delicious for special cultures, bring new discoveries to their researchers.
  5. 5. Red Sea Urchins, British Columbia ● Red sea urchins carpet a kelp forest off British Columbia. The marine invertebrates are important links in the marine food chain. Fish pick at the urchins, which feed on bits of algae.
  6. 6. Sea Urchins, British Columbia ● A nontoxic dye highlights water currents surrounding sea urchins off Vancouver Island, British Columbia. These small, spiny echinoderms are found in oceans all over the world.
  7. 7. Fire Urchin, Indonesia ● The spines of a fire urchin form a multicolored flower off Komodo Island, Indonesia. The blue swellings on the tip of each spine are filled with venom.
  8. 8. Sea Urchin, Bonaire Island ● A sea urchin is nestled in a coral formation off Bonaire Island. Urchins feed on algae and invertebrates - a recent study found that the sound of their teeth scraping on reefs can cause a rise in ocean noise.
  9. 9. Sea Urchin, Channel Islands ● Sea urchins brandish their spines on the seafloor near the Channel Islands. Scientists recently discovered that the eyeless invertebrates “see” by detecting light with their spines.
  10. 10. Green Sea Urchins, Alaska ● Green sea urchins, chitons, and sea stars cluster in a tidal pool off Alaska’s Aleutian Islands. Sea urchins and sea stars are close relatives.
  11. 11. Fire Urchin, Papua New Guinea ● The bright red color of a fire urchin warns predators that its spines are poisonous. Sea otters are the major predators of sea urchins.
  12. 12. Our sea urchin ● We found this sea urchin on the Atlantic seaboard of Tenerife island.
  13. 13. ● We should take a good care of environment to provide the survival of such beautiful animals.
