Giant jellyfish season began several weeks ago in Dar es Salaam with an invasion of massive, white Rhopilema nomadicas (nomad jellyfish). These jellies can grow up to 10 kg (22 lbs) of weight, and its bell is commonly 40-60 cm (16″-24″) in diameter, but can be up to 90 cm (35.4″). European Union lists it as one of the worst invasive marine species. Make sure to steer clear as it can cause very painful injuries to humans as it has vermicular filaments in the mouth arms.
