Sharks of Zuma Beach: What Swims Beneath the Malibu Waves

Zuma Beach (Malibu, CA) sits in the **Southern California Bight**, a nutrient-rich transition zone where cool California Current waters meet warmer subtropical flows. This diversity supports a notable cast of shark species—most harmless, all fascinating. Here are the sharks documented near Zuma:

Common Residents & Visitors

• Leopard Shark (*Triakis semifasciata*) — **Most commonly seen.** Slender, strikingly patterned (saddles/spots). **Harmless.** Aggregates in shallow sandy bays (La Jolla, Santa Monica Bay) summer/fall to gestate. Feeds on crabs, worms, clams. Snorkelers' favorite.
• Soupfin Shark (*Galeorhinus galeus*) — **Schooling migrant.** Formerly fished heavily for liver oil (vitamin A) and fins. **Near Threatened (IUCN).** Feeds on small fish, squid. Poses no threat.
• Brown Smooth-hound (*Mustelus henlei*) — **Small, bottom-dwelling.** Common in bays/estuaries. Eats crustaceans. Harmless.
• Spiny Dogfish (*Squalus acanthias*) — **Cold-water schooling shark.** Venomous dorsal spines (defense only). Migrates seasonally. Sustainable fishery certified (MSC). Not aggressive.

Less Common but Present

• Sevengill Shark (*Notorynchus cepedianus*) — **Apex predator of kelp forests/bays.** 7 gill slits (primitive trait). Up to 3 m. **Potentially dangerous**—rarely implicated in bites (usually provoked/spearfishing). Prefers deeper channels; occasionally nearshore.
• Pacific Angel Shark (*Squatina californica*) — **Ambush predator, ray-like.** Buries in sand. **Camouflage master.** Can bite if stepped on/handled. **Near Threatened.**

Seasonal & Occasional Visitors (Nearby Waters)

• Shortfin Mako, Blue Shark, Thresher — Pelagic, offshore. Rarely nearshore.
• Great White Shark (*Carcharodon carcharias*) — **Juveniles (1.5–3 m) increasingly common in SoCal Bight** (Santa Monica Bay, Ventura) due to protections & prey (sea lions, fish). **Adults** rare nearshore. **Risk extremely low**—but real. Zuma lifeguards monitor.

Risk Reality Check

• **Unprovoked bites in LA County:** Extremely rare (decades between incidents).
• **You're more at risk from:** Rip currents, stingrays (shuffle feet!), sun exposure, driving PCH.
• **If you see a shark:** Stay calm, maintain eye contact, slowly exit. Don't splash.

Conservation Context

Many listed species are **overfished globally**. CA has **strong protections**: gillnet bans, MPAs, white shark protection (1994). Zuma's sharks are indicators of a recovering coastal ecosystem. Seeing a leopard shark glide under your board is a privilege—not a threat.
