The unicorn of the sea — the amazing secrets of the narwhal

### Not a horn, but a "giant front tooth"

A cutting-edge sensory organ for survival, not the horn of a mythical creature

- **What it really is** — not a horn on its head, but an asymmetrical canine tooth that pierces through the upper lip and grows outward in a spiral.
- **Acting as an antenna** — packed with countless nerve endings, it precisely detects the ocean water's temperature, pressure, and salinity.
- **A caution** — if the tusk breaks — whether from males fighting or breaking through hard ice — it never grows back.

### A diver that roams 1,500m underwater

Remarkable diving ability to find food in extreme conditions

- **Diet** — it dives into the deep, dark ocean to hunt halibut, cod, squid, and shrimp.
- **Diving depth** — it can dive as deep as 1,500m, among the deepest of any marine mammal.
- **Dive duration** — on a single breath, it can stay underwater hunting for up to 25 minutes.
- **Breathing holes** — to breathe, it travels as far as 1.4km underwater searching for a gap in the ice.

### Under the ice is its perfect hideout

Why the narwhal never leaves the cold, harsh icy sea

- **A safe zone** — it can hide deep beneath thick ice, away from polar bears and human hunters.
- **A sleek back** — with no dorsal fin, it can swim pressed close right up against the underside of the ice.
- **Predator defense** — its predator, the orca, has a huge dorsal fin that keeps it from following into narrow gaps under the ice.

### "I'm right here!" — a voice that finds family

A special sound-based system that connects mother and calf

- **A unique signal** — each individual creates its own special "contact call."
- **Mother and calf** — when separated in the vast ocean, they make a specific sound to check each other's location.
- **A name tag of the sea** — this highly developed sound acts like a name tag, letting members recognize each other within the group.
