What happens if you step on a rockfish?
Stonefish have 13 spines lining its back that release venom under pressure. If you inadvertently step on a stonefish thinking it’s a harmless rock, it will pop up its dorsal spines and release venom from two sacs at the base of each spine. Unsurprisingly, the more venom that is injected, the worse it is for you.
What is the most poisonous fish in the ocean?

How old can rockfish get?
Biology. The Shortraker rockfish lifespan is thought to average about 120 years, the second-longest of all varieties of rockfish to the rougheye rockfish, estimated at 140 years. This makes rockfish some of the world’s oldest living fish. Like many other rockfishes it is a viviparous species.
What is the oldest living fish?
Methuselah
Biologists at the California Academy of Sciences believe they host the world’s oldest living aquarium fish in the world — and her name is Methuselah. Scientists believe that Methuselah, an Australian lungfish, is about 90 years old.
What if you step on rock fish?
If you inadvertently step on a stonefish thinking it’s a harmless rock, it will pop up its dorsal spines and release venom from two sacs at the base of each spine. Unsurprisingly, the more venom that is injected, the worse it is for you. Stings result in terrible pain, swelling, necrosis (tissue death) and even death.
How old are yelloweye rockfish?

How do you estimate the age of a fish?
Scientists can estimate the age of a fish by examining an ear bone known as the otolith, which contains growth rings similar to the annual age rings found in a tree trunk. Animal longevity remains a puzzle to biologists. Some researchers have found that smaller individuals within a species tend to live longer than their bigger brethren.
