SeaHarmony welcomes all ocean scientists, ocean educators, resource managers, artists, and ocean related organizations and community groups.
Green turtles, like all sea turtles, grow very slowly. Different populations of turtles grow at different rates based on habitat quality, availability and abundance of food sources, and environmental conditions. A typical, healthy green turtle will grow only half an inch (1-2 cm) per year until they reach maturity. It likely takes between 25-40 years for a green turtle to reach maturity and reproduce for the first time.
If all of the salt from the ocean were dried up and spread out evenly over the land continents, the salt would be about 5 feet high!
In the ocean, as on land, elements are constantly being cycled through different animals. An important player in this cycling process is bacteria. Bacteria can take organic matter, such as a fish carcass, and break it down to some of the essential compounds required for life. Bacteria sometimes get a dirty reputation, but they’re actually nature’s recyclers!
The air above the ocean is intricately connected to the ocean floor miles below. Carbon dioxide dissolves into the surface of the ocean from the atmosphere and phytoplankton use the carbon dioxide for photosynthesis. Other organisms at the surface eat the phytoplankton and when they die they sink down towards the sea floor. Creatures living in the deep sea depend on this falling matter for food.
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)
