About Spider Crab

Spider crab (Loxorhynchus grandis) — also called sheep crab, occasionally California king crab — is a majoid crab (family Epialtidae, the "decorator crabs") that lives on mixed bottom throughout SoCal and central California. A mature adult has a carapace 8 to 10 inches across and a leg span approaching 3 feet. They weigh 3 to 8 lbs. Females are smaller than males.

They are not a Cancer crab. This matters regulatorily. Rock crabs (red, brown, yellow, slender) are all in or near genus Cancer and regulated under § 29.85(c). Spider crabs are in Loxorhynchus, family Epialtidae — a completely separate crab lineage. Because they're not mentioned by name in § 29.85, § 29.90, or any species-specific regulation, they default to the § 29.05 general invertebrate rules: 35 per day, no size minimum, year-round, with MPA and SCUBA restrictions.

Morphologically, the long legs are diagnostic. No other California crab has leg-to-body ratio like a spider crab. Juveniles decorate their carapace with sponges, algae, and bryozoans — the decoration serves as camouflage and reaches peak complexity in small individuals. Adult males groom smooth; adult females retain some decoration. That variability explains why a boatload of spider crabs can look like multiple species on first glance.

How to Catch

Spider crabs are almost always caught incidentally on lobster hoop nets, Dungeness pots, or rock crab traps. Target fishing for them is unusual because they move slowly and are distributed across mixed bottom that anglers are usually soaking for another species. But when they show up, they're legal, year-round, no-minimum — so keep them if you want.

Hoop net is the primary method. Same rig as lobster and rock crab: 30-inch collapsible net, bait box with squid/mackerel/salmon skins, 45–90 minute soaks in 30 to 200 feet over mixed rock/sand. Spider crabs walk to the bait slowly, don't leave quickly, and often stack multiple per pull.

Crab trap with Recreational Crab Trap Validation extends the soak. Spider crabs enter and don't leave; they're slow.

Freedive in SoCal kelp forests produces spider crabs if you're looking for them. Adults often den under ledges or in kelp-holdfast labyrinths. Tickle stick to coax them out, gloved hands on the carapace (not the legs — autotomy).

SCUBA restrictions. South of Yankee Point (Monterey County), SCUBA hand-capture of spider crab is legal. North of Yankee Point, § 29.05 restricts SCUBA invertebrate take to urchins, rock scallops, and Cancer-genus crabs — spider crabs don't qualify. Freedive is legal statewide.

Handle by carapace only. Legs are fragile and the crab will drop them to escape. A leg-handled spider crab often ends up as just a leg.

Eating Profile

The long legs are the point. White, sweet leg meat that's closer in texture to snow crab than Dungeness — flaky, pull-apart, delicate. Body meat is sparse and typically not worth picking. A 3-lb spider crab produces about 6 oz of leg meat; a 5-lb one produces 10 oz.

Cooking: boil or steam 12–15 minutes (longer than Dungeness because the legs are thick and the shell is heavier). Shock in ice water. Crack legs with kitchen shears or a nutcracker. Serve with butter.

Spider crab is probably the single best California crab for pure leg-meat consumption. If you can get 5–8 of them, you have a meal that stands up to any snow crab feed.

Common Mistakes

  • Assuming they're in the 35-bag Cancer limit. They're NOT. Spider crab is a separate § 29.05 invertebrate. However, the practical bag ends up looking the same (35/day).
  • SCUBA-taking north of Yankee Point. Illegal for non-Cancer crabs under § 29.05. Freedive or hoop-net only in NorCal.
  • Handling by the legs. Autotomy. The legs break off. Handle by the carapace.
  • Cooking like Dungeness (8–10 minutes). Too short for spider crab — shell is thicker. 12 to 15 minutes.
  • Discarding because "not a real crab." Genuinely excellent eating. Many who've tried both prefer spider crab leg meat to Dungeness body meat.
  • Ignoring MPA boundaries. No-take MPAs apply to all invertebrates including spider crab. Check the map before dropping gear.

Month-by-Month

  • Year-round legal under § 29.05 (no closed season).
  • Jan–Mar: Available but most effort is on Dungeness and lobster. Spider crab mostly incidental catch.
  • Apr–Jun: Dungeness winding down, lobster already closed (spring). Spider crab continues as incidental catch and begins to be a dedicated target for SoCal crabbers.
  • Jul–Sep: Peak effort period. Dungeness closed everywhere, rock crabs and spider crabs carry summer. Hoop net trips specifically for spider crab pick up.
  • Oct–Dec: Lobster season opens October 2, 2026 — most Southland diver/angler effort shifts to lobster. Spider crab continues as incidental catch on lobster hoop nets. Plenty come up; keep what you want up to the 35/day.

Where to Catch Spider Crab (Sheep Crab) in California

  • Mixed rock and sand bottom, kelp forest perimeters, and pier pilings
  • Channel Islands (Catalina, San Clemente, Santa Cruz) — deep sand/rock transitions
  • Palos Verdes and SoCal coast rocky fringes
  • Santa Barbara mainland and Point Conception south
  • Monterey Bay over sandy bottom
  • Often seen 'decorating' carapace with sponges, bryozoans, and algae for camouflage

Conditions & Habitat

Water Temp

48–62°F; cool-water SoCal and Central Coast species

Typical Depth

10–500+ ft; most recreational take 30–200 ft on mixed rock/sand bottom and kelp edges

Diet

Algae, sponges, bryozoans, small invertebrates, carrion — slow-moving generalist; decorates carapace with sponges and algae

How to Catch Spider Crab (Sheep Crab)

Techniques

  • Hoop net in 30–200 ft on mixed bottom — they walk into nets baited for lobster or rock crab
  • Crab trap with Recreational Crab Trap Validation (not required for hoop nets)
  • Freedive or SCUBA hand collection on kelp-forest edges (SoCal only — SCUBA for non-Cancer invertebrates is restricted north of Yankee Point)
  • Incidental catch — spider crabs come up on lobster hoop nets and Dungeness pots frequently
  • Long legs are fragile and break off — handle by the carapace, not the legs

Lures & Baits

  • Hoop net (30-inch) with bait box — same rig as lobster and rock crab
  • Bait: salmon skins, mackerel, sardine carcass (spider crabs are slow but persistent scavengers)
  • Tickle stick for coaxing out of kelp or hollow on dive
  • Mesh game bag — spider crab legs tangle easily in fine-mesh bags

Line & Leader

Hoop net: 100–250 ft of 3/8-inch polypropylene to a marked buoy (same as lobster rig). No rod-and-reel fishing — this is net or dive.

Rod & Reel Combos

  • No rod — hoop net on hand-pulled rope or rail puller
  • Dive kit: standard SoCal kelp-forest setup, game bag, tickle stick, knife
  • Pot rig: same as Dungeness — 150 ft rope, validated buoy, rot-away destruct panel

Regulations

Spider crab / sheep crab (*Loxorhynchus grandis*) is **not a Cancer-genus crab** and is **not covered by 14 CCR § 29.85**. It falls under **14 CCR § 29.05** as a default-regulated invertebrate. Daily bag limit: **35 per day** — this is the general § 29.05 limit for 'all invertebrates for which the take is authorized and for which there is not a bag limit otherwise established in this article.' **No minimum size**. **Year-round season**. Legal methods (§ 29.80 / § 29.05): hoop net, crab trap (with Recreational Crab Trap Validation), crab snare, hand, skin-dive, and SCUBA (**SCUBA hand-capture restricted** — § 29.05 limits SCUBA take of invertebrates north of Yankee Point, Monterey County, to sea urchins, rock scallops, and Cancer-genus crabs only; spider crabs do NOT qualify for SCUBA take north of Yankee Point). South of Yankee Point, SCUBA hand-capture is permitted. No-take Marine Protected Areas (MPAs) prohibit all take. This species is also separately regulated commercially under § 126 (commercial sheep crab permit, 95,000-lb annual quota); the recreational rule set above is independent of that.

Did You Know?

Spider crabs 'decorate' themselves. Juvenile *Loxorhynchus grandis* actively attach sponges, hydroids, algae, and bryozoans to hooked setae (bristles) on their carapace, camouflaging themselves from predators. A well-decorated spider crab can be nearly invisible on a sponge-covered rocky bottom. Adult males lose this behavior and groom their carapaces smooth — which is why the same species can look drastically different depending on age and sex.

Frequently Asked Questions

Yes — same species (*Loxorhynchus grandis*), two common names. 'Spider crab' refers to the long-legged body plan; 'sheep crab' refers to the fuzzy carapace on molting and mature individuals (covered with algae, sponges, and hydroids, giving a wool-like texture). Some sources also call it 'California king crab' — that name is sometimes misapplied. *Loxorhynchus grandis* is a majoid (family Epialtidae), not related to true Alaskan king crabs (family Lithodidae).
