Please know that the availability of these food sources can vary depending on the leatherback sea turtle’s location and the specific environmental conditions. Additionally, their preference for jellyfish makes up a significant portion of their diet.
Primary food sources
The primary food source for leatherback sea turtles is jellyfish. These turtles are highly specialized predators adapted to feed on gelatinous organisms. They have distinctive adaptations in their mouth and throat, including backward-pointing spines called papillae, which help them capture and consume jellyfish efficiently.
While jellyfish make up the majority of their diet, leatherback sea turtles can also consume a variety of other gelatinous organisms. This includes different species of sea jellies, comb jellies (ctenophores), and other soft-bodied invertebrates. Their feeding habits are opportunistic, and they may consume other types of prey if available in their habitat.
Leatherback sea turtles are considered keystone species in marine ecosystems due to their role in controlling jellyfish populations. They help maintain a balance in the ocean food web by preventing jellyfish from overpopulating and negatively impacting other marine organisms.
Also, the availability of food sources can vary depending on the turtle’s location and the specific environmental conditions of its habitat. Conservation efforts are crucial to protect leatherback sea turtles and ensure the preservation of their essential role in marine ecosystems.
