Pigs Recorded Using maritime pet supplies Tools For The First Time

The fish fans sand to unearth the bivalve, takes it into its maritime pet supplies mouth, swims several metres to a rock which it uses as an anvil by smashing the mollusc apart with sideward thrashes of the head. This behaviour has been recorded in a blackspot tuskfish on Australia’s Great Barrier Reef, yellowhead wrasse in Florida and a six-bar wrasse in an aquarium setting. These species are at opposite ends of the phylogenetic tree in this family, so this behaviour may be a deep-seated trait in all wrasses. Tool use behaviour has been observed in the Tanimbar corella in captivity. Hyacinth macaws have been repeatedly observed to use tools when breaking open nuts, for example, pieces of wood being used as a wedge.

  • Pigs also understand abstract representations and can apply this skill to play video games using a joystick.
  • This behavior is demonstrated by dropping prey from a height onto a hard substrate in order to break the prey’s shell open.
  • Tool use is found in at least thirty-three different families of birds.
  • Over time, and across generations, this has led humans to have culturally created billions of know-how types, with the vast majority being beyond the human zone of latent solutions.

They will take sticks and place them in termite mounds or ant hills and pull them out covered in tasty insect snacks. They will also use rocks to smash open nuts and other hard food items. African bush elephantsIn the wild, elephants are known to use tools for a variety of reasons. They will frequently break small trees and sticks and use them to scratch hard-to-reach places like their backs. They are also known to throw rocks at things they want to break, though that is mostly relegated to more aggressive animals.


Construction of the more complex hooked tools typically involves choosing a forked twig from which parts are removed and the remaining end is sculpted and sharpened. New Caledonian crows also use pandanus tools, made from barbed leaf edges of screw pines (Pandanus spp.) by precise ripping and cutting although the function of the pandanus tools is not understood. Chimpanzees are sophisticated tool users with behaviors including cracking nuts with stone tools and fishing for ants or termites with sticks. These chimpanzees not only use these sticks to fish out their meal, but they in fact build their own ‘tool kits’ to do so, as observed in the Republic of Congo.

Tools within this zone can be individually and socially learned , but tools outside this zone cannot. This renders non-human primates unable to improve their tools in complexity beyond this zone, towards levels of human technology. Captive western lowland gorillas have been observed to threaten each other with sticks and larger pieces of wood, while others use sticks for hygienic purposes. In another group of captive gorillas, several individuals were observed throwing sticks and branches into a tree, apparently to knock down leaves and seeds. Gorillas at Prague zoo have used tools in several ways, including using wood wool as «slippers» when walking on the snow or to cross a wet section of the floor. Birds are among the most prolific tool users, and one of the most startling examples is the Egyptian vulture.

Kea, a highly inquisitive New Zealand mountain parrot, have been filmed stripping twigs and inserting them into gaps in box-like stoat traps to trigger them. Apparently, the kea’s only reward is the banging sound of the trap being set off. New Caledonian crows have also been observed performing tool use behaviour that had hitherto not been described in non-human animals. This involves the crow inserting a stick into an object and then walking or flying away holding both the tool and object on the tool. Tool use is found in at least thirty-three different families of birds.

This two-inch-long Indonesian cephalopod has been observed retrieving discarded coconut half-shells, swimming with them up to 50 feet away, and then carefully arranging the shells on the seafloor for later use. A 2018 study even revealed that crows can build compound tools, as crows observed by the researchers were able to attach small objects together to create a stick long enough to reach a food source. Interestingly, even young crows exhibit this behavior without having seen adults do it, which suggests it’s part of their natural behavior.

Alternative options to using antibiotics for disease prevention in animals include improving hygiene, better use of vaccination, and changes in animal housing and husbandry practices. Many countries have already taken action to reduce the use of antibiotics in food-producing animals. For example, since 2006, the European Union has banned the use of antibiotics for growth promotion. Consumers are also driving the demand for meat raised without routine use of antibiotics, with some major food chains adopting “antibiotic-free” policies for their meat supplies.
