[2][a 3] where the posterior border of the boarded flooring is sharp into a saw form. A color of the carapaces is yellow, and a blackish brown spot enters [2]. It is in this way thought that I make mimesis to underwater coral [2]. As for the color of the shell, yellow [2].

[3][a 3] which the eating habit eats chi men in animal food mainly [2], but the soft coral and Crustacea, echinoderm, alga eat. The game which remove the corpse of the coral in a bill and a foreleg, and is in the gap of a rock and the coral using a bill 啄 ばむ [2] [3].

It may be said that the egg is edible [2]. Poison may be included in meat from eating habit, and there is the example that the person who ate was fatally poisoned [2]; [4]. In addition, the antidote does not exist [4].
A deck was considered to be raw materials of the tortoise shell work (べっこうざいく) in Japan [2]; [3].
[2][a 3] where the number of the habitation decreases sharply by the destruction of the habitat by the development, bycatch, a deck by the fishery or edible indiscriminate hunting. Japan imported the decks of this seed in large quantities from all parts of the world and continued importing the decks of this seed even after Washington Convention took effect in 1975 [2]. However, criticism from the global community was big, and the import of decks of this seed was prohibited in 1993 [2].

It was confirmed by NPO corporation, a sea turtle meeting in Japan that a hybrid to have both loggerhead turtle and characteristics of the hawksbill turtle in Oshima, Amami in June, 2013 laid eggs.
