By highlighting threatened or endangered species, SeqOnce hopes to draw attention to conservation efforts. As biologists, we believe humanity is better served when ecologies are maintained and there is diversity of life.


The rhinoceros is a magnificent animal, but three of the five species are critically endangered: Javan rhino, Sumatran rhino, and the Greater One-Horned rhino.

These rhinos are threatened by poaching and habitat loss. We can help through efforts such as Sumatran Rhino Rescue. The White rhino was nearing extinction, yet has been brought back from the brink through extensive conservation.

Poison Dart Frogs

These frogs are native to rainforests of South and Central America. About a quarter of the more than 200 species are listed as threatened or critically endangered the blue poison dart frog (Dendrobates tinctorius aureus ) is one of these. The primary threat to poison dart frogs is the loss of habitat due to logging and clearing of the rainforest.

SeqOnce supports protecting and conserving endangered and threatened species. A portion of our profit goes to helping those engaged in the critical fieldwork of conservation.
