Unable to defend themselves, octopuses often fall prey to predators. [76] This makes most octopuses effectively semelparous . The larger Pacific striped octopus (LPSO) is an exception, as it can reproduce repeatedly over a life of around two years.
Many prey animals, and to defend against seed predation also seeds of plants, [55] make use of poisonous chemicals for self-defence. [ 51 ] [ 56 ] These may be concentrated in surface structures such as spines or glands, giving an attacker a taste of the chemicals before it actually bites or swallows the prey animal: many toxins are bitter ...
Opisthoteuthidae are a group of octopuses characterized by a web of skin in between their arms. They broad U-shaped shell that support muscles for a pair of small fins on the mantle, these fins are far less developed than other families in Cirrina and essentially only act as stabilizers when the animal swims (using a medusoid motion of the arms and webbing).

The more scientists study octopuses, the more we learn how fascinating these creatures really are. Octopuses are incredibly intelligent, displaying all kinds of amazing behavior like completing ...
A molluscivore is a carnivorous animal that specialises in feeding on molluscs such as gastropods, bivalves, brachiopods and cephalopods.Known molluscivores include numerous predatory (and often cannibalistic) molluscs, (e.g.octopuses, murexes, decollate snails and oyster drills), arthropods such as crabs and firefly larvae, and, vertebrates such as fish, birds and mammals.

Octopuses taste by touching objects with their tentacles. Here's a sampling of the coolest animal discoveries from 2020. 22 discoveries this year changed our understanding of how animals ...
Since these octopuses do not live for long, they mature rapidly and can hunt for food to feed themselves right after hatching. [8] Hatchlings feed on amphipods or mysid shrimp. [9] [10] As they grow, the list of what they eat grows with them. California two-spot octopuses eat anything they can find, like fish and crustaceans.
The team followed the octopuses for 13 hunts, during which they observed groups of between two and 10 fish working with each octopus. These hunting groups typically included several species of ...
