SeaHarmony welcomes all ocean scientists, ocean educators, resource managers, artists, and ocean related organizations and community groups.
So little is still understood about our deep oceans. One study recently discovered that the deep ocean had 898 species in an area about half the size of a tennis court. Over half of these species had never been identified before by scientists, and that’s not even including all the microscopic organisms that can be found.
Why are people so worried about plastic pollution in the ocean? Plastics break into smaller plastic pieces, but never completely break down. The tiny plastic pieces get eaten by small fish and crustaceans, which then get eaten by bigger fish, albatrosses, whales, and sharks. These plastics can cause serious harm once ingested resulting in starvation, and internal injuries. Remember, plastics are forever.
Ocean acidification happens when increased carbon dioxide in the air dissolves into the ocean. The excess carbon dioxide lowers the pH of our oceans, making them more acidic. This becomes a threat for sensitive animals like corals and shellfish because it reduces their ability to build calcium carbonate skeletons.
Despite their misleading name, sea cucumbers are not vegetables of any kind. These slow moving, soft bodied relatives of starfish and sea urchins live on the sea floor eating organic particles and microscopic marine animals. Sea cucumbers are important animals on coral reefs because they help remove dead material from ocean sediments.
The mimic octopus is an incredible animal that can impersonate the appearance and movement patterns of a lionfish, crab, jellyfish, and many other animals. However, scientists have recently found a small jawfish whose coloration copies the mimic octopus, mimicking one of the octopus’ arms!

The coral animals that build the foundation framework of coral reef ecosystems are sensitive to these thermal stress events that occur in the marine environment and can respond to this stress in a visually striking way known as coral “bleaching”. When corals bleach, the symbiotic algae held in their tissues are lost, generating the stark white color giving this response its name. Under normal... (more)
