Researchers voice concern over poisonous sea slugs
Researchers have voiced concern about a new species of neurotoxic side gilled seagull that are having a dramatic increase in population off the coast of Argentina. The new species, similar to Pleurobranchaea maculata (pictured above) which is found off Australia and New Zealand, has no predators, and is hence able to outcompete indigenous species.
