A new study reported in the Biological Bulletin provides the first direct evidence that the chromosomes of a sea slug called the Eastern emerald elysia (Elysia chlorotica) have some genes that come from the algae it eats. The genes help sustain photosynthetic processes inside the sea slug that provide it with all the food it needs. The Eastern emerald elysia (Elysia chlorotica). Image credit: Patrick Krug. A team led by Prof Sidney Pierce from the...

The Geography cone snail (Conus geographus) attempting to capture fish prey; as the snails approach potential prey, they release a specialized insulin into the water, along with neurotoxins that inhibit sensory circuits, resulting in hypoglycemic, sensory-deprived fish that are easier to engulf with their large, distensible false mouths; once engulfed, powerful paralytic toxins are injected by the snail into each fish.

The marine defaunation experience is much less advanced, even though humans have been harvesting ocean wildlife for thousands of years; the recent industrialization of this harvest, however, initiated an era of intense marine wildlife declines. If left unmanaged, scientists predict that marine habitat alteration, along with climate change, will exacerbate marine defaunation. Image credit: Jenny Huang / CC BY 2.0.
