Answer 1

Hint:This fish is the world's most poisonous fish species and second most poisonous vertebrate after golden dart frog. This fish have tetrodotoxin that can cause serious illness and death.

Complete answer:
Poisonous fish are poisonous to be consumed. This produces toxins that are not eliminated by animals' digestive systems. Poisonous fish contain a powerful toxin, but they don't bite, sting or stab in order to supply the toxin, but are poisonous to eat because the human digestive system doesn't kill the toxins in their body.

Even if clown fishes are edible, people are strongly advised not to eat them because of the slimy material on their skin.

Fantastic source of omega-3 fatty acids are the Eel fish. It also contains a large quantity of calcium, magnesium, potassium, selenium, manganese, zinc and iron.

Swordfish is a very common cooking fish. The meat is typically sold as steaks because of the large swordfish, which are grilled several times. Swordfish meat is relatively firm and can be cooked in ways that are not capable of more delicate fish.

Puffer fish species are the most poisonous in the world and second most poisonous vertebrate after golden dart frog. The active agent, tetrodotoxin which occurs in the inner organs and often in the skin, paralyses human victims' muscles which can be destroyed by suffocation. The highly skilled chefs use parts of a closely related species, blowfish in Japan to produce a delicacy called fugu.

Thus, the correct answer is option D. i.e., Puffer fish.

Note:The potent and deadly toxins tetrodotoxin and saxitoxin that can cause serious illness and death can be found in puffer fish. These are poisons to the central nervous system which are deadlier than cyanide. After eating poisonous fish, the symptoms start in 20 minutes to 2 hours.
