Marine Animals

Euphausia superba

Antarctic krill is a small, shrimp-like crustacean that forms the foundation of the entire Antarctic food web, supporting whales, seals, penguins, and countless fish species. Despite its tiny individual size, its total biomass is estimated to be one of the largest of any animal species on Earth, gathering in massive swarms that can stretch for kilometers and be seen from space.

Hapalochlaena lunulata

The blue-ringed octopus is one of the most venomous marine animals in the world despite being barely larger than a golf ball, found in tide pools and shallow reefs across the Indo-Pacific. Its venom contains tetrodotoxin, a toxin powerful enough to cause paralysis in humans, though the octopus itself is docile and only bites when directly provoked or handled.

Octopus vulgaris

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

Dugong dugon

The dugong is a large marine mammal closely related to manatees, spending its entire life grazing on seagrass meadows in the shallow coastal waters of the Indian and western Pacific Oceans. It is the only strictly herbivorous marine mammal that lives exclusively in the sea, unlike manatees, which sometimes venture into freshwater rivers.

Tridacna gigas

The giant clam is the largest living bivalve mollusk in the world, capable of growing shells over a meter across and living for a century or more anchored to the same spot on a coral reef. Rather than actively hunting for food, it hosts millions of photosynthetic algae within its colorful mantle tissue, drawing most of its energy from sugars the algae produce using sunlight.

Aurelia aurita

The moon jellyfish is one of the most common and widely-distributed jellyfish species, drifting through coastal waters worldwide in large seasonal blooms.
