Endangered Species is the fifth studio album by Japanese girl band eX-Girl.

Unlike previous albums it was first released outside Japan, on Jello Biafra's Alternative Tentacles label (catalog number Virus 313).

Zorek is only on the front cover of the album but played on the tour, after Keikos departed.

Some tracks feature previous band members Fuzuki (drums).

As usual, the album was produced by the band's mentor and collaborator, Hoppy Kamiyama.
