What Is a Horn Shark?

Horn sharks are small sharks found in the eastern Pacific Ocean, especially along the coasts of California and Mexico. They typically grow to about 3–4 feet long and have a blunt head with ridges above their eyes, giving them a slightly “grumpy” look.

Their name comes from the two sharp spines (“horns”) located in front of their dorsal fins, which help protect them from predators.

They are generally harmless to humans and spend most of their time resting on the ocean floor.

 

Unique Behaviors and Adaptations

Horn sharks behave very differently from most sharks:

• Bottom walkers: Instead of swimming constantly, they use their fins to “walk” along the seafloor.
• Nocturnal hunters: They hide during the day and come out at night to feed.
• Powerful teeth: Their front teeth grab prey, while their back teeth crush hard shells like crabs and sea urchins.

They usually stay in small territories and return to the same hiding spots every day.

 

 

 

 

 

 

 

 

 

 

Habitat and Diet

 Horn sharks prefer shallow coastal waters, especially rocky reefs, caves, and crevices.

• Typical depth: 6–36 feet
• Environment: rocky reefs, algae beds, sandy bottoms
• Temperature: around 70°F (21°C)

Their diet includes:

• Crabs
• Sea urchins
• Mollusks
• Small fish

They use strong jaws to crush hard-shelled prey—one of their most impressive abilities.

 

 

 

 

 

 

 

 

 

 

 

Reproduction: The Corkscrew Egg

One of the coolest things about horn sharks is how they reproduce. Females lay spiral-shaped eggs that look like corkscrews. These eggs are wedged into rocks so they don’t drift away.

It can take 6–9 months for a baby shark to hatch!

 

 

 

 

 

 

 

 

 

Where Can You See Horn Sharks?

Horn sharks are popular in aquariums because of their manageable size and calm behavior. Here are some places where you can see them (or similar small shark species):

 The Boca Aquarium is an intimate, family-friendly aquarium located inside a jewelry store in Boca Raton, Florida.

• Features a shark tank, reef tanks, and seahorse exhibits
• Offers live shark feeding shows
• Designed for quick visits (about 20–25 minutes)

Since it's not an oversized aquarium, it gives visitors a close-up look at sharks and marine life in an accessible setting. See a full list of our exhibits here!

Several other aquariums across the United States feature horn sharks in their exhibits. The Monterey Bay Aquarium in California often showcases local Pacific marine species, including horn sharks, while the Aquarium of the Pacific in Long Beach provides visitors with opportunities to learn about the diverse marine life found along the West Coast. Seeing a horn shark in person allows guests to appreciate the incredible diversity of shark species and discover that not all sharks are large, fast-swimming ocean predators.
