Professor Oak has three Pokémon at the start of Red and Blue: Bulbasaur, Charmander, and Squirtle. These Pokémon can only be found in Oak’s laboratory, so they are rare. A team of scientists in Professor Oak’s lab research the Pokémon. Squirtle is possibly an endangered species of sea turtle.

Kemp's ridley sea turtle (Lepidochelys kempii) is the smallest species of sea turtle as well as the rarest (Rhodin et al. 2010). It is listed as critically endangered by the The International Union for Conservation of Nature (Wibbels and Bevan 2019). Kemp's ridley sea turtle migrates from the Gulf of Mexico to the Atlantic. However, these migrations are being impacted by rising sea temperatures (Fritts et al. 1983). Habitat destruction, climate change, and other human activity place the populations at further risk (Griffin et al. 2019).

The green sea turtle (Chelonia mydas) is a large species of sea turtle (Swash and Still 2005). Adults can weigh over 400 pounds though they are strictly herbivores, feeding on sea grasses and algae (Howell and Shaver 2021; Sea Turtle Conservancy). There are two genetically distinct populations due to geographic barriers with one residing in the Atlantic Ocean and the other in the Pacific (National Geographic 2005).
