07 Strangest and Creepiest Fish Species

More than 70% of the planet’s surface is covered-by oceans, which produce 50–80% of the oxygen and support a variety of life. Yet so little is known about our seas and the many deep-water species. More than 80% of our ocean is un-mapped, unseen, and unexplored, with less than 10% mapped using modern sonar equipment.

While the waters are home to much beautiful fish and sea creatures, others have unattractive physical features. Some of these creatures are scary, enough to keep the weak of the heart awake at night.

#1. Atlantic wolffish

Anarhichas lupus, also called the seawolf, Atlantic catfish, and wolf eel inhabits the west and east coastlines of the Atlantic Ocean. Atlantic wolffish are purplish-brown, grayish-green, olive green, or bluish gray. Big fish with elongated, tapering bodies and large heads. The largest specimen measured 1.5 m (5 ft) and weighed 18 kg (40 lb).

#2. Spotted handfish

The spotted handfish (Brachionichthys hirsutus) is an Australian handfish. It measures up to 12 cm (4.7 in) and lives 5 to 10 m deep (16 to 33 ft).

#3. Blobfish

Psychrolutes marcidus is a deep-sea fish in the Psychrolutidae family. It dwells off the coasts of Australia, Tasmania, and New Zealand at 600 to 1,200 m (2,000 to 3,900 ft) deep, where the pressure is 60 to 120 times that at the surface.

#4. Humpback anglerfish


Melanocetus johnsonii is a black seadevil of the Melanocetidae family. It’s a soft-bodied, dark brown or black anglerfish found 100 – 1500 m (330 – 4,920 ft) deep. Due to the lack of light at such depths, the Humpback anglerfish uses bioluminescence to hunt prey.

#5. Stargazers

The Uranoscopidae family includes roughly 51 species (one extinct) in eight genera and is distributed worldwide in shallow and deep saltwaters, including stargazers. They feature a broad upward-facing mouth and eyes on top of their giant heads, which is how they got their name. When the enormous stargazer Kathetostoma giganteum is considered, these species range in size from 18 to 90 cm.

#6. Oyster toadfish

Opsanus tau, also known as oyster toadfish, oyster toad, ugly toad, or oyster cracker, is a fish found in the Northwest Atlantic and belongs to the Batrachoididae family. The oyster toadfish is often olive brown to yellowish with brown oblique bar markings and has a fat belly and a broad, flat head.

It may grow to a maximum length of 43.2 cm (17 in), and the name “oyster toadfish” refers to its scaleless skin, which is covered in thick mucus and occasionally has warts.

#7. The Striated frogfish (or Hairy frogfish)

Antennarius striatus, often known as the Hairy frogfish or Striated frogfish, is a species of saltwater fish. It can grow to a maximum length of 22 cm (8.7 in), but the average size is 10.0 cm (4 in).

This tiny fish can range in color from yellow to brownish-orange, gray, green, virtually white, or brown, and it may have or lack black stripes or elongated spots. It may also change its pigment pattern and hue to mix in with its surroundings.
