Sea Slugs Steal Superpowers! 🌊✨

Dear reader,

Sea slugs steal things too, and they specifically steal organelles! Doesn’t it sound like the endosymbiosis theory?

Sea Slugs:

Sea slugs are colorful, soft-bodied animals that live in the ocean. They look like snails without shells. They come in many shapes and bright colors, and some have superpowers like making their own food from sunlight!

Kleptosomes:

Imagine tiny bags inside sea slugs' bodies. These little bags hold special parts (like tiny green machines called chloroplasts) stolen from the plants or algae the slugs eat. These stolen parts help the sea slug use sunlight to make food—just like plants do!

Sea Slugs Steal "Superpowers" by Repurposing Prey Cells

Harvard biologists discovered sea slugs possess a remarkable ability called kleptoplasty, enabling them to steal functional organelles like chloroplasts from algae. Slugs encapsulate these stolen organelles in specialized compartments called kleptosomes, preventing digestion and allowing them to continue photosynthesis, effectively turning slugs into solar-powered organisms. Another slug, the Berghia nudibranch, similarly repurposes venomous stinging cells from its prey, creating a defensive mechanism against predators. These findings highlight sophisticated evolutionary strategies and suggest potential biomedical and sustainable energy applications.

My take: So, this news of sea slugs stealing organelles can be seen as proof of the theory of endosymbiosis and the long speculation that mitochondria was once a bacteria not commonly found in human/mammal cells but we acquired it.
