The hawksbill sea turtle (Eretmochelys imbricata) is a critically endangered sea turtle.
Adult hawksbill sea turtles typically grow to 1 m in length, weighing around 80 kg on average.
The hawksbill sea turtle has been shown to be biofluorescent and is the first reptile recorded with this characteristic. It is unknown if this is derived from the turtle’s diet, which includes biofluorescent organisms like the hard coral Physogyra lichtensteini.
While they are omnivorous, sea sponges are their principal food; they constitute 70–95% of the turtles diet.
Hawksbills evidently reach maturity after 20 years. Their lifespan is unknown.
