The ocean consists of a variety of creatures that might be scarier and more dangerous than sharks, and a wide range of marine species, including cnidarians and crustaceans, could pose significant injury and even death to humans. There are various creature that surpasses the competency of sharks in terms of causing adverse injury, but such creatures may not have strength, which is equivalent to sharks. Â Â Â Â
Stonefish
Some species of sharks account for attacking humans, namely great white, bull shark and tiger shirk. It is worth noting that sharks are known for their aggressive attacks on humans, accounting for several injuries and even death every year. However, some water creatures, even in terms of smaller than sharks, cause more injury and are known for their stealth movement underneath the ocean.  In the world there are around 1,200 species of venomous Fish that may pose catastrophic harm to the human.
Amongst the most known venomous Fish, stonefish is identified to be the most terrifying and deadly, and it is also way more malicious than sharks, which are way bigger compared to them. The stonefish is generally found in reef habitats in the Indo-Pacific region, and one of the key characteristics of this Fish with its ability to camouflage itself perfectly in corals. Â Stonefish have 13 spines lining its back that are capable of releasing venom under pressure. If anyone mistakenly steps on a stonefish venom, it forms two sacs at the base of each spine release, resulting in very bad pain, tissue death, swelling and even death. As a result, deadly stings of stonefish require immediate medical attention. Â
Box Jellyfish
Box Jellyfish are particularly found on warm coastal waters across the globe, and lethal species particularly found in northern Australia and Indo Pacific region. This includes the most venomous Jellyfish called Australian Box Jellyfish.  The Box Jellyfish were so-called for their body shape. The body of this sea creature is covered with tiny darts that consist of poison.
Animals and people who come in contact with Box Jellyfish could have a greater risk of injury, and the poison that is released from the body is enough to be injected with the poison may cause cardiac arrest, paralysis and even death. The venom of the Box jellyfish can also cause neurotoxicity. Box Jellyfish survivors can experience significant pain for weeks and often have considerable scarring where the tentacles made contact.  Â
Puffer Fish
Pufferfish and species which are closely related to the Tetraodontidae are toxic, with some among the most venomous species in the world. In addition, puffer fish is a lethal source of food poisoning, with a mortality are up to 60 per cent of individuals who ingest this neurotoxin. Tetrodotoxin,which is a potent neurotoxin, has been found among several species of puffer fish that may carry this neurotoxin, including toadfish, sea squab, goldfish, swellfish and balloonfish.Â
The above-mentioned species of Puffer Fish are found throughout shallow waters of the Pacific, Atlantic and Indian Oceans and seemingly acquire the toxin via microorganisms in their diet. Despite the toxicity of this neurotoxin, it may have therapeutic uses. As the poison of Puffer Fish has a paralysis effect, it may be used as an analgesic to treat different sorts of painful conditions.Â
Stingray Â
The chance of being attacked by a stingray is very small. These creatures spend their days on burned sand on the seabed, besides gliding peacefully around the ocean. Stingrays are not as ferocious as sharks, but they are also recognised to injure people who unknowingly disturb them specifically standing on them. The stinger of a stingray releases a complex venom, which may lead to intense pain in a puncture wound. Â However, death due to Stingray attack is very rare, and very few documented cases have been seen over the last couple of years.
Lionfish
Lionfish can be dangerous to humans because of its potent venom. However, incidents of people being stung are rarely fatal. A sting of Lionfish is more likely to have some fairly unpleasant effects that range from nausea and pain to dizziness, convolutions, numbness and fever. As Lionfish are predacious marine animals, there have been reports of aggression towards fishermen and divers. Besides, such incidents are found to be rare, and hence, the case of injury which is caused by Lionfish is limited to certain regions.  Â
