The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
After hunting, they bring food back to the den to feed in a safer environment and avoid predators. [31] Shells, bones, and other feeding debris pile up outside of the den, creating "den litter" that is commonly used by scientists and divers to find E. dofleini. [25] [32] [28]
Most young octopuses hatch as paralarvae, [73] Octopus larave in particular are planktonic for weeks or months. Octopus larave feed on shrimps, isopods and amphipods, eventually settling on the ocean floor and developing into adults. [81] Octopus species that produce larger eggs instead hatch as benthic animals similar to the adults.
A resourceful octopus carried a coconut across the ocean floor.
The common octopus is easily adapted to captive conditions and has a rapid growth rate of 5% body weight per day. [21] It also has a high feed conversion rate with 30–60% of ingested food being incorporated in its own weight, [23] [24] and a high fecundity of 100,000–500,000 eggs per female. [23]
Octopus maya is known to feed primarily on benthic prey such as crustaceans, bivalves, fish, gastropods, other octopuses, and even birds.Two specific prey items that O. maya commonly feeds on are blue crab (Callinectes sapidus) and the crown conch snail (Melongena corona bispinosa).
Callistoctopus macropus, also known as the Atlantic white-spotted octopus, white-spotted octopus, [2] [3] grass octopus or grass scuttle, is a species of octopus found in shallow areas of the Mediterranean Sea, the warmer parts of the eastern and western Atlantic Ocean, the Caribbean Sea, and the Indo-Pacific region.
However, previous efforts to farm octopus have struggled with high mortality, while attempts to breed wild-caught octopus ran into problems with aggression, cannibalism and self-mutilation.
