From the problem of monitoring rare populations to the danger of poachers exploiting distribution data, the problems of learning endangered species require inventive options from researchers. Hawksbill sea turtle (Eretmochelys imbricata), Atlantic Ridley sea turtle (Lepidochelys kempii), and leatherback sea turtle (Dermochelys coriacea) are all listed as endangered species whereas the loggerhead sea turtle (Caretta caretta) is considered threatened under the protection of the ESA.

Ultimately, what makes a species endangered is some marked change to the species itself or to its ecosystem (e.g., elevated exploitation, loss of habitats, etc.). Many, if not most, marine mammal species thought of being susceptible to extinction reached this situation due to human exercise (i.e., harvesting).
