Blue Lined Octopus | Hapalochlaena fasciata
“The octopus starts its life with the size of a pea and when fully grown, it reaches the size of a golf ball. These have powerful toxins contained in its saliva, which is fatal. When threatened, 50 to 60 blue rings on its body appear brighter, making its presence known to predators.” .
