Giving read this sentence from the first paragraph: another, more hideous, fiend of the deep is the gulper eel. what is the main purpose of this sentence in the paragraph? to connect a new topic to the main idea to provide contrast to the main idea to argue against a counter argument to provide a counterpoint to the previous creature

This question is incomplete, here´s the complete question.  

Atlantic Hagfish

Part eel, part sea snake, this sea serpent may have inspired many stories. Lacking the scales that most fish have, the hagfish secretes the most amazing slime to protect itself. This slime may be used to suffocate predators. The slime includes small fibers that make it almost impossible to remove. But the hagfish's truly horrific nature lies in what it does to its prey, not its predators. With an excellent sense of smell that compensates for almost total blindness, the hagfish will locate and latch on to a victim. With a circle of razor sharp teeth, the hagfish bores a hole into the side of its now-doomed prey. Once the hole is complete, the hagfish just welcomes itself inside for a meal of fish innards. It essentially eats its prey from the inside out.

Like other deep-sea monsters, however, hagfish are seldom a nuisance to humans. They live most of their lives at depths of up to 5,600 feet. In fact, they prefer a soft sea bottom so they can quickly bury themselves to hide from threats.

Gulper Eel

Another, more hideous, fiend of the deep is the gulper eel. This creepy critter is part eel and part giant pouch. Like a pelican's enormous pouch-shaped mouth, the mouth of the gulper eel can open quite wide to gulp prey. It has a long tail tipped with a glowing organ that is used to lure in prey. Thanks in part to its tail, the gulper can reach up to six feet in length. Because its tail is so thin, it is not able to pursue prey with any speed, but it can scoop up hundreds of small crustaceans or shrimp in one bite. Often swimming through these prey groups with its mouth wide open, its large jaws allow it to feed on squid and other creatures much larger than itself.

Gulper eels have only been studied because they sometimes get caught in the nets of fishermen. The depths they inhabit make it quite difficult for scientists to study them. They can go as deep as 6,000 feet, well beyond the abilities of humans to pursue them.

To argue against a counter argument

To provide a counterpoint to the previous creature

To provide a counterpoint to the previous creature

Explanation:

This quote from Monsters of the Deep is the beginning of the description of the Gulper Eel. Before that, the text had described the Atlantic Hagfish. The idea that this eel is 'more hideous' provides a counterpoint with the Atlantic Hagfish. Even though they are both described as horrific, it´s the eel that gets the most frightful description, being deemed as more repulsive than the previous creature.
