Where to find Spanish shawl nudibranchs: the best dive sites and seasons, the hydroid patches they hunt, lookalikes to rule out, and how to photograph one.

Spearfishing can be the most selective way to take seafood — or a fast way to damage a kelp forest. Here's how to do it legally, selectively and with respect.
Tom Okafor ·
How scientists combine survey records, satellite data and climate projections to map where kelp grows today — and forecast where forests will survive in 2050.

Meet the speckled sanddab (Citharichthys stigmaeus): a palm-sized flatfish that vanishes into sand, feeds the whole kelp coast, and signals bottom health.

The Pacific spiny lumpsucker is a walnut-sized armoured fish that clamps to kelp and eelgrass with a suction-disc belly. Biology, range, where to look.

Golden kelp drops its spores for two short weeks in Gulf St Vincent. Field notes from a collection week run on the Kudjela Rangers' calendar, not ours.

The spot prawn lives half its life male and half female, hides in cold rocky depths, and anchors one of the Pacific's most admired trap fisheries.
Dr. Theo Nakamura ·
The spotted ratfish is a deep-bodied chimaera with green eyes, a venomous spine and a forehead clamp — a living fossil that haunts Pacific kelp waters by night.

On the Berwickshire coast, one of Britain's first voluntary marine reserves protects tangle kelp forest, wolf-fish dens and clear North Sea water.

Carbon and nitrogen isotope ratios let ecologists read what reef animals actually ate — and whether kelp carbon reached them. Here's how the method works.
Dr. Mara Ellison ·
Kelp carbon carries a chemical fingerprint. Stable isotope analysis lets ecologists trace it from blade to grazer to fish — and test restoration claims.

The staghorn sculpin cruises Pacific estuaries from Alaska to Baja, tolerates fresh water, and carries venomous antler-like spines on its head.
Dr. Mara Ellison ·
Pterygophora californica grows a woody stipe that stands for decades, sheltering understory life while faster kelps rise and fall around it. Species profile.

The Steller sea lion is the largest of the eared seals — a tonne of muscle-hauling out beside North Pacific kelp forests. Its biology, range and hard-won recovery.
Dr. Mara Ellison ·
Norway turned wild kelp into an industry with trawls and a five-year rotation. The history, the ecosystem debate and what taretrawling taught the world.
Naomi Reyes ·
Storms tear kelp forests apart — and keep them young. How wave forces damage kelp, why disturbance is essential to forest health, and what a stormier future means.

Between Vancouver Island and the BC mainland, the Fraser River's plume shapes bull kelp beds, herring spawns and whale water. A coastal atlas guide.
Dr. Mara Ellison ·
At the Salish Sea's front door, Pacific upwelling meets inland outflow over bull kelp forests and tidal races. A coastal atlas guide to the strait.
Dr. Lena Fischer ·
Meet the striped seaperch, a live-bearing surfperch of Pacific kelp beds — and a close look at how viviparity works in a fish that births on the reef.
Dr. Theo Nakamura ·
Striped shore crab (Pachygrapsus crassipes) species profile: the bold, fast, green-striped crab of Pacific rocky shores — sprinter, grazer and lab superstar.
Dr. Theo Nakamura ·
Meet the striped surfperch (Embiotoca lateralis), the copper-striped, blue-flecked surfperch of rocky shores and kelp beds from Alaska to Baja California.
Tom Okafor ·
Stubby rose anemone (Urticina coriacea) species profile: a leathery, crimson anemone of northern rock and cobble, from Arctic seas to California kelp forests.
Dr. Mara Ellison ·
Freshwater doesn't stop at the shoreline. Submarine groundwater springs up through seabeds on kelp coasts worldwide — carrying nutrients, cool refuge and sometimes trouble.

Sunomono is a ten-minute wakame and cucumber salad — and a masterclass in the vinegar dressings of Japanese cooking. Ratios, technique, variations.
