Hairy angler fish

Hairy angler fish Caulophyrne spp.The name of the hairy angler Caulophryne polynema means "stalked toad with many filaments". The filaments are long, sensory spines that the anglerfish uses to sense vibrations in the water around it.

The hairy angler is covered in sensory spines and hairs (called neuromasts), which detect vibrations in the water made by passing prey. With its large cavernous mouth, filled with sharp, fang-like teeth, and a highly expandable stomach, an angler fish can swallow prey larger than itself.

Colossal squid.

Colossal squid are only known from a few specimens, estimates put its maximum size at 12 to 14 metres. It is the largest known squid species and the world’s largest invertebrate. It is believed to have the largest eyes in the animal kingdom.
The animal was first described in 1925 from two tentacles found in the stomach of a sperm whale. The squid’s known range is from Antarctica to the southern extremities of South America, South Africa and New Zealand.
Analysis of sperm whale stomachs suggests the colossal squid makes up three quarters of the diet of large sperm whales and it is likely there are large numbers of them in Antarctic waters.
Only a handful of colossal squid have been sighted. One was caught in the net of a Russian trawler in the Ross Sea at depth of 760m in 1981, another found near the surface in 2003 and another near South Georgia Island was brought up from a depth of 1625 metres on a toothfish longline in 2005.
It is believed that colossal squid hunt large fish, such as toothfish, and other squid.

Gulper Eel(Eurypharynx pelecanoides)

The gulper eel, known scientifically as Eurypharynx pelecanoides, is one of the most bizarre looking creatures in the deep sea. Its most notable attribute is the large mouth. This enormous mouth is much larger than the eel's body. The mouth is loosely hinged, and can be opened wide enough to swallow an animal much larger than itself. The hapless fish is then deposited into a pouch-like lower jaw, which resembles that of a pelican. In fact, this eel issometimes referred to as the pelican eel. The gulper's stomach can also stretch to accommodate its large meals. This giant mouth gives the eel its other common name of umbrella mouth gulper.

The Dumbo Octopus can be found in any ocean and is known to have been found any where upto approximately 7,000 meters below sea level.
We believe there to be around 37 different species of Dumbo Octopus, they can usually be found close to the sea bed and can grow up-to 20cm in length.
The Dumbo Octopus is strange compared to others of its kind as it prefers to swallow its prey whole. When down on the sea bed Dumbo Octopus will feast mainly on worms and crustaceans, and when away from the sea bed they will eat pelagic cope-pods.

The Dumbo Octopus gets its name from the two fins which look like and are situated like ears. ‘Dumbo’ will swim using these larges fins and with the help of its arms it is a formidable swimmer and this shows when ’Dumbo’ needs to get somewhere fast.. like away from a predator!
Not much is known about the Dumbo Octopus as both male and female are varied in their size and also in the pattern of their suction pads, it is suggested however that males may sometimes have larger suckers.

Piglet Squid, Helicocranchia pfefferi: This funny looking squid is about the size of a small avocado and can be found most commonly in the deepwater (greater than 100 m or 320 ft) of virtually all oceans. Its habit of filling up with water and the funny location of its siphone with a wild-looking 'tuft' of eight arms and two tentacles had prompted scientists to name it the piglet squid.
