Ocean Animals
Covering over 70% of the planet, the ocean is home to everything from microscopic plankton to the largest animal ever known.

Blue Whale
Balaenoptera musculus

Bottlenose Dolphin
Tursiops truncatus
MammalThe bottlenose dolphin is one of the most widely-recognized and intelligent marine mammals, found in temperate and tropical oceans worldwide.

Clownfish
Amphiprion ocellaris
FishThe clownfish is a small, brightly-colored reef fish famous for its symbiotic relationship with sea anemones, whose stinging tentacles it is immune to.

Common Octopus
Octopus vulgaris
Marine AnimalThe common octopus is a remarkably intelligent, boneless marine invertebrate found in coastal waters worldwide, renowned for its problem-solving abilities and rapid camouflage.

Leatherback Sea Turtle
Dermochelys coriacea
ReptileThe leatherback is the largest sea turtle species in the world and the only one without a hard bony shell, ranging farther into cold water than any other reptile.

Moon Jellyfish
Aurelia aurita
Marine AnimalThe moon jellyfish is one of the most common and widely-distributed jellyfish species, drifting through coastal waters worldwide in large seasonal blooms.

Narwhal
Monodon monoceros
MammalThe narwhal is an Arctic whale famous for the male's long spiraled tusk, which is actually an enormous protruding canine tooth, earning it the nickname 'unicorn of the sea'.

Polar Bear
Ursus maritimus
