The best way to tell the difference between the two is to look at their feet! Tortoises have elephant-like, unwebbed feet, and turtles have webbed feet for swimming. While tortoises are technically turtles, not all turtles are tortoises. Tortoises are exclusively land-dwelling animals, and if they are put in deep water they will drown. Tortoise – There are a few differences between turtles and tortoises.
Some of these are farm raised, and some are wild caught.
In the United States, nearly 97% of those harvested per year are exported to Asia.
Turtle for Dinner – Turtles are considered a delicacy in China, and are also used in traditional Chinese medicine. Shell-Less Turtles? – While all turtle species have shells, not all species have hard Some kinds of aquatic turtles have soft, leathery shells instead of hard shells! Leatherback sea turtles and softshelled turtles are two examples. This keeps predators from being able to reach its vital body parts. When presented with danger, a turtle retracts its head and legs inside its shell. Personal Protection – Their unique shells provide these animals with a mobile protection system. The top half of the shell is called a carapace, and the bottom half is called a plastron. The shell is fused to the ribs and backbone of the turtle, making it impossible for it to leave its shell. Stupendous Shells – Turtle shells are an amazing evolutionary adaption. Some species have traits unique to them in particular, and some adaptations are held by all turtle species. The scientists also used the data gathered to pinpoint important hawksbill sites in the region-information they're sharing with governments to encourage stronger protection for all the places these turtles need to go.With such a huge variety of species, there are virtually endless fascinating facts about turtles. And they suggest that other hawksbills (and perhaps other sea turtle species) may respond this way to rising ocean temperatures over time. These findings are the first real-time evidence of sea turtles changing their behavior in order to cope with warmer temperatures. In November 2014, they announced what the transmitters revealed: every summer, when coastal waters reached around 90☏, the hawksbills migrated to deeper, cooler waters, where they stayed until temperatures dropped again. Members of the initiative-called the Marine Turtle Conservation Project-attached satellite transmitters to 90 turtles at nesting sites in Iran, Qatar, Oman and the UAE, then tracked the animals' movements. 
Despite that heat, the region is home to numerous hawksbills-and in 2010, the Emirates Wildlife Society and WWF teamed up to study them. Sea surface temperatures in the gulf can climb as high as 98☏ in the summer, and air temperatures can hit 122☏. So how might turtles respond to warmer beaches and warmer oceans as global temperatures rise? To gain insight, a team of marine scientists studied hawksbill turtles already living in a place with extreme heat: the Persian Gulf. Sea turtles' lives are dictated, in large part, by heat: subtle temperature variations shape their embryonic development, determine their sex, and influence their growth and nesting activity.
