Lamprey are jawless fish, characterized by their toothed, funnel-like sucking mouth.
These turtles are native to Asian countries, particularly Vietnam and Laos. They are characterized by their broad head, and lack of a shell. They are also an endangered species as they are often hunted for meat, eggs, decoration, pets, and for use in medicine.
These deer don’t look too different from other deer, except for one feature – the fangs that grow on the male species.
