Octopus

Introduction

An octopus is a type of marine mollusk with eight legs, two eyes and an elongated body, usually found in the ocean. Beyond its strange appearance, the octopus is one of the most intelligent, adaptable, and versatile creatures in the world. More fundamentally, an octopus is a living organism whose physical structure and behavior have been shaped through centuries of adaptation and evolution. The journey of an octopus from its birthplace in the depths of the ocean to a dinner plate tells us a lot about the interrelatedness of organisms, the interconnectedness of ecosystems, and the significance of a sustainable seafood industry.

Biology of an Octopus

Before exploring the journey of an octopus from the sea to your dinner plate, let's start by taking a closer look at the octopus itself. An octopus is an invertebrate animal closely related to squid and cuttlefish, and is a part of the Cephalopoda family. This group of animals are characterized by their large heads and tentacles, as well as their jet-propelled locomotion. Interestingly, each octopus tentacle contains millions of suction cups that can be used for movement and to latch onto prey. Octopus species vary in size, from the giant Pacific octopus with a maximum size of 16 feet and 46 pounds, to the smaller, elusive pygmy octopus with an average size of less than two inches.

Known for their skillful camouflage and deceptive attacks, octopuses are carnivorous animals that mainly feed on small crustaceans and fish. They hunt using their tentacles and suckers, which allow them to collect prey without having to see it. Anecdotal evidence suggests that octopuses are crafty; some have been known to open jar lids or even use stones as tools while hunting.

Life Cycle

All octopuses begin their life cycle with the same simple act: a single octopus lays thousands of eggs in the safety of her den in the deep ocean. During mating, male and female octopuses come together, and the male uses his specially adapted third arm, or hectocotylus, to transfer sperm packets to the female. After mating, the female immediately begins laying fertilized eggs, which she protects and cleans for weeks before they hatch. As the eggs hatch, thousands of tiny octopus larvae emerge and immediately face a fleeting chance for survival in the hostile environs of the ocean.

As larvae, octopus must compete for food, evade predators, and find suitable habitats for growth. When it finds a hospitable environment, the larva will settle and transform into a juvenile octopus, a small, clever hunter with a camouflage-assisted lifestyle. The life of a juvenile octopus is often short-lived as within one to two years, the octopus will reach adulthood, completing its full life cycle.

Habitat

Octopuses can be found living in the shallow coastal reefs and oceans of all the planet's major abyssal plains. Certain species of octopuses prefer deep sea habitats, while others are found in shallow waters, usually near shorelines and in estuaries. In different climates, octopuses live in a variety of habitats, from rocky coastlines to coral reefs.

Within their habitats, octopuses use their webbed feet and excellent sense of sight, touch and smell to find food, avoid predators, and create temporary structures around themselves. Octopuses are also incredibly mobile and will often travel to different areas within their habitat, or migrate greater distances when resources, such as food, become scarce.

Fishing

When an octopus is ready to be eaten, it has generally met its end through commercial fishing. Octopus fishing is a unique activity that often requires specialized equipment and techniques. A range of methods are used to capture octopus, including trawl nets, traps, and longlines. The most commonly used method involves the use of baited traps — or “pots” — which are placed in the water and left overnight to collect octopus drawn to the bait. The most common bait is chunks of fish, crab, and squid, but other types of bait can be used as well. After being left for a certain period of time, the traps are raised and sorted for octopus.

Markets and Supply Chain

Once caught, octopus spends much of the supply chain on board the fishing vessel. Here, the octopus are graded according to size, sex, and overall quality, with the best specimens making their way to market. After being graded, the octopus are stored in chilled seawater and brought to shore where they enter the global seafood supply chain. The octopus are then typically delivered to processing centers, where they are packed and frozen, to be shipped to market.

Once in market, octopus are sold to retailers and foodservice outlets. Fresh octopus is sold in its whole form, while frozen and canned octopus are sold in pieces. In the foodservice industry, whole fresh octopus is often used as ingredients in restaurant prepared dishes, while frozen, canned octopus is used as an ingredient in a variety of prepared dishes. Regardless of format, octopus is a versatile ingredient and is popular in many cuisines around the world, from Mediterranean-inspired seafood dishes to East Asian-style stir-fries.

Sustainability

As a type of seafood, sustainability considerations must be taken into account when harvesting, transporting, and marketing octopus. Most octopus fishing is managed in accordance with local regulations and conditions, designed to ensure both the health of the species and the livelihoods of local fishermen. Efforts are taken to mitigate the risk of bycatch and ensure that the population of octopus is not threatened for future generations.

One of the more controversial aspects of octopus fishing is the use of Octopus Traps, which have been criticized by some as potentially damaging to ocean ecosystems. In response, some fisheries are now using specific designs that are aimed at minimizing environmental damage. On the marketing side, many supermarkets and retailers are increasingly focused on sourcing sustainable seafood, ensuring that their suppliers meet key sustainability benchmarks.

Conclusion

The journey of the octopus from its unusual beginnings in the depths of the deep ocean to the dinner plate of seafood fans around the world is an incredible narrative. Through evolution and adaptation, the octopus has become one of the most unique and remarkable creatures in the world. As we move forward, however, it is essential that we recognize the importance of sustainable practices in procuring and marketing octopus. After all, the ocean ecosystem is an interdependent web with no room for excess.
