Slug photosynthesis
Webb11 juli 2013 · The importance of photosynthesis on the nutrition of photosynthetic sea slugs has been addressed by comparing animal weight and survival rates of starved specimens (deprived of exogenous food sources and unable to feed heterotrophically) kept in the laboratory under dark (thus unable to acquire photosynthates from their … WebbThese ‘stolen’ plastids provide sea slugs with a long-term supply of organic carbon and energy. This augmented nutrient supply brings many benefits in terms of survival, body planning, reproductive traits, and body regeneration. However, the mechanisms of maintenance of chloroplasts and photosynthesis in sea slugs are poorly understood.

WebbKleptoplasty or kleptoplastidy is a symbiotic phenomenon whereby plastids, notably chloroplasts from algae, are sequestered by host organisms.The word is derived from Kleptes (κλέπτης) which is Greek for thief.The alga is eaten normally and partially digested, leaving the plastid intact. The plastids are maintained within the host, temporarily … Elysia chlorotica feeds on the intertidal alga Vaucheria litorea. It punctures the algal cell wall with its radula, then holds the algal strand firmly in its mouth and sucks out the contents as from a straw. Instead of digesting the entire cell contents, or passing the contents through its gut unscathed, it retains only the chloroplasts, by storing them within its extensive digestive system. It then take…

Webb7 juli 2024 · Juvenile sea slugs eat the nontoxic brown alga Vaucheria litorea and become photosynthetic – or solar-powered – after stealing millions of algal plastids, which are like tiny solar panels, and storing them in their gut lining, according to the study published online in the journal Molecular Biology and Evolution.
