The colossal squid, also known as the Antarctic or giant cranch squid, is a species of deep-sea squid that can grow up to 43 feet in length and weigh up to 1,000 pounds. It is considered one of the largest invertebrates in the world and is known for its large eyes, sharp beak, and powerful tentacles with hooked suckers. The species is found in the Southern Ocean and is known to live at depths of up to 2,000 meters. Despite their immense size, very little is known about the biology and behavior of colossal squids as they are elusive creatures that are rarely seen or captured.
What Do Colossal Squids Eat?
Colossal squids are believed to primarily eat fish and other deep-sea squids. They have been found with remains of fish such as the Patagonian toothfish (Dissostichus eleginoides) in their stomachs. They also have been observed to feed on other deep-sea creatures such as lanternfish, squid, and also crustaceans like krill and amphipods.
They have sharp beaks, hooks, and suckers on their tentacles which help them to catch their prey. Due to the fact that the Colossal squid lives in the deep sea and is very rarely seen, much of what is known about its feeding habits comes from studying the stomach contents of those that have been caught or washed ashore.

Do colossal squids eat sharks?
There is no clear evidence that colossal squids actively hunt and eat sharks. While it is possible that a colossal squid could potentially consume a small shark if it came across one, it is not a known part of the species’ diet. The majority of the diet of the colossal squid consists of fish and other deep-sea squids. While many deep-sea creatures such as sharks, bony fish, and other squids are known to be on the menu of the giant and colossal squids, it is not a regular or preferred diet. The Colossal Squid is also known to be a prey item of the sperm whales which are known to hunt them.
How does the colossal squid feed?
The Colossal squid is known to use its sharp beak and hooked tentacles to capture its prey. The hooks on its tentacles are specialized and are used to grasp and hold prey while the beak is used to bite and tear pieces of flesh from the prey.
The Colossal Squid’s tentacles are lined with rows of suckers that have tiny, sharp hooks on the rim. These hooks are used to grasp and hold prey. The squid’s beak, which is located at the base of its tentacles, is used to bite and tear pieces of flesh from its prey. Once the prey is captured and subdued, the squid uses its radula (a tongue-like organ with rows of teeth) to shred the prey into smaller pieces that can be easily consumed.
The Colossal Squid is also known to use its arms and tentacles to lure fish into striking range, using bioluminescent bacteria that are present on its body. This adaptation is common among deep sea creatures and is known as counter-illumination.
Due to the deep-sea habitat of the Colossal Squid, and the rarity of sightings, much of what is known about the feeding behavior of this species comes from studying the stomach contents of those that have been caught or washed ashore.

What kills the colossal squid?
The main predator of the Colossal Squid is the Sperm Whale. These whales are known to feed on a wide variety of deep-sea creatures, and the Colossal Squid is no exception. They have been found with remains of Colossal Squids in their stomachs. The whales locate their prey by diving to great depths and using their echolocation to detect the squids.
Other possible predators of the Colossal Squid include the Giant Squid and other deep-sea creatures like the Humboldt Squid. In addition, it is also possible that some of these squids fall prey to fishing boats, which accidentally catch them in their nets.
The Colossal Squid is also known to be vulnerable to deep-sea trawling, fishing gear, and pollution. Climate change and ocean acidification could also have a negative impact on their population and survival.
Due to their elusive nature, it is difficult to know how many Colossal Squids are killed by predators or other causes. However, it is known that the species is considered rare and is listed as “data deficient” by the IUCN Red List of Threatened Species.
