These strange water creatures are a cross between a jellyfish and a stingray. Despite this, they can't actually breed with one another, but a group of scientists have actually spliced DNA from both of these aquatic organisms to create something more complicated. As the name suggests, they originated from Jamaica; this is where the scientists released some of the stingrays and jellyfish into the water in order to further study them. The most common jellyrays come in three colors, which are blue, mercury/silver, and yellow---blue being females, mercury/silver being males, and yellow being asexual. Because of this, like ordinary jellyfish, they can reproduce sexually and asexually. Also, since jellyrays tend to be immortal, they can often shapeshift to preserve their infinite lifespans. In fact, jellyrays once existed some 900 million years ago in another faraway place before they were extinct, although a person with supernatural resistance to all pain had once gathered a ship full of jellyrays to transport them to Earth, further suggesting that they didn't come from just Jamaica only. Regardless, a team of scientists have been working together to preserve their populations and keep them in other parts of the Earth, though some of them moved to another Earth-like planet to continue their projects.


The Jamaican jellyray has a poison much stronger than one ordinary jellyfish and one regular stingray put together. In fact, its poison is proven to be three times stronger than that of a box jellyfish's, capable of killing at least a few hundred people or animals. A single drop of their venom inside a person's bloodstream can leave them permanently paralyzed with pain; because of this, their poison is carefully extracted by scientists in order to study its effects and reverse engineer it to create an antidote. They are also quite a delicacy in other restaurants, specifically in neighboring Asian countries. The top part can at least be eaten raw if they're captured alive and killed without cooking, though even in death, their stingers can still last forever, so one must never make physical contact with their dangerous stingers. Only a few species of large snapping sea turtles are completely immune to their poison as they can safely touch their stingers with their mouths before completely devouring them.


A jellyray has a limited diet consisting of larvae, algae, tinier kinds of fish, and even fish eggs. They cannot be captured alongside other kinds of fish as their poison can render their meat extremely inedible, resulting in serious food poisonings even when cooked. In some cases, they are often speared to death or lured in special nets designed to lure various kinds of said aquatic animal. Strangely, another way to kill a jellyray is to pour salt all over them, which even weakens the strength of their toxic tentacles.


The green jellyrays are in fact a second variation known as chameleon jellyrays. As they behave like ordinary chameleons, they can actually camoflauge underwater as their skins can morph to match their surrounding environments, waiting for the perfect moment to strike. While they can be extremely vicious and dangerous, they don't actually hang around near beaches despite people seeing them washed ashore. In fact, these kinds of jellyrays only have enough poison to kill ten people, but being exposed to sunlight for too long can cause them to shrivel up and die within minutes---they can only survive harsh sunlights as long as they're in water. They also share the same diet as an oridnary jellyray. Unfortunately, in spite of being edible, they otherwise don't have a flavored taste when cooked... at least in some occasions.
