Un orque et son soigneur à Marineland (Antibes – FRANCE).
L’orque ou l’épaulard est un mammifère marin carnivore. Il est de couleur noir ou brun foncé et blanc. Le mâle peux avoir une mangeoire de 1,8 m de haut. Sa peu est huileuse, molle et élastique ce qui facilite la propulsion dans l’eau. Ils ont entre 40 et 50 dents sur chaque mâchoires.
Il habite dans tous les océans, les hautes mers et près des côtes du monde mais surtout dans les océans plus froids que dans les tropiques. Ils sont souvent proches du rivage.
L’épaulard peut avoir des petits à partir de 14 à 15 ans. Ils ont de 4 à 5 petits et la femelle les gardent pendant 17 mois soit 510 jours dans son ventre, cela veux dire qu’ils sont des mammifères vivipares. La femelle allaite ses petits pendant 6 mois, puis ils commencent à manger du poissons. La femelle s’occupe de ses bébés pendant 2 ans. Plusieurs mères s’occupent de l’éducation de leurs bébés elles-mêmes et leurs apprend leur propre technique de chasse.
Les orques sont des animaux très sociaux, familiaux, ils sont des migrateurs et ils sont toujours en groupe. Comme les dauphins, les épaulard aiment beaucoup jouer et faire des chorégraphies.

The killer whale (Orcinus orca), also referred to as the orca whale or orca, and less commonly as the blackfish, is a toothed whale belonging to the oceanic dolphin family. Killer whales are found in all oceans, from the frigid Arctic and Antarctic regions to tropical seas. Killer whales as a species have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as sea lions, seals, walruses, and even large whales. Killer whales are regarded as apex predators, lacking natural predators.
Killer whales are highly social; some populations are composed of matrilineal family groups which are the most stable of any animal species. Their sophisticated hunting techniques and vocal behaviors, which are often specific to a particular group and passed across generations, have been described as manifestations of culture.
The IUCN currently assesses the orca’s conservation status as data deficient because of the likelihood that two or more killer whale types are separate species. Some local populations are considered threatened or endangered due to prey depletion, habitat loss, pollution (by PCBs), capture for marine mammal parks, and conflicts with fisheries. In late 2005, the "southern resident" population of killer whales that inhabits British Columbia and Washington state waters were placed on the U.S. Endangered Species list.
Wild killer whales are not considered a threat to humans, although there have been cases of captives killing or injuring their handlers at marine theme parks. Killer whales feature strongly in the mythologies of indigenous cultures, with their reputation ranging from being the souls of humans to merciless killers.
