Saltwater & Coastal

Spinner sharks can clear the surface in a rotating strike, but the legal field marks are quieter: a black-tipped anal fin and a first dorsal set behind the pectoral.

Atlantic sharpnose sharks take common inshore baits. Identify the long snout, lip furrow, rear-set dorsal, and white side spots before applying the current one-per-person federal rule.

Bonnetheads use a smooth shovel-shaped head to search shallow flats for crabs and other prey. They can digest seagrass too—but the evidence deserves a more careful claim than the headline usually gets.

Blacktips run beaches, bars, bays, and inlets. The adult’s pale anal fin separates it from a spinner, while current Atlantic HMS rules make identification and a fast wet release part of the rig.

Striped Marlin follow bait, squid and warm water across the Pacific, and that tells you far more about where to look than any top-speed claim. Most recreational fish get tagged and released.

The red rockfish everybody calls vermilion can be a hidden second species that only genetics can separate. Depth changes the odds, and a fish from deep water needs a descending device to go back down.

A silvergray’s long lower jaw with a knob on the end is the check that keeps it out of the Dusky pile. It lives deep, can reach about 82 years, and needs a real plan for release.

Dusky Rockfish school over offshore banks and gullies, often well above the bottom. Until 2004 the name also covered the shallow fish now called Dark Rockfish, so color alone won’t tell you which one is in your hands.

Black rockfish school above nearshore reef and kelp instead of hugging bottom, take six to eight years to mature, and give birth to live young. Fish the layer they’re in, and check the belly and jaw before you name a dark fish.
