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 you could take all of the bigger organisms of the ocean (whales, sharks, fish, squid) and add up their total weight, and then took all of the microscopic organisms (like plankton) in the ocean and added up their total weight, which one would weigh more? You might be surprised to hear that the microscopic organisms weigh over 40 times more than all other organisms in the ocean combined!
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.
Scientists in Canada got a surprise while doing studies on human forensics. To look at how bodies decompose, they tossed pig carcasses into so called "dead zones", areas of low oxygen in the ocean. However, much to their surprise, sharks, lobsters, and other scavengers risked going into these suffocating conditions and ate their experiment!
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!

Unlike many other discoveries of whale falls in the ocean, crew on the Nautilus found this relatively recent fall in a mid-stage of ecological succession, providing an exciting look into life in the deep sea. Whale falls are importance influxes of nutrients and energy to the deep sea. This pulse in food availability becomes... (more)
