Named for its silver belly
Argentiventris comes from the Latin for silver and belly, a nod to its silvery underside, which is slightly washed with red.

Rosy in front and bright yellow behind, the yellow snapper is one of the most important commercial fish in the southern Gulf of California. Many of them spend their first year among mangrove roots before moving out to the reef.
Rosy red at the front, turning bright yellow to orange over most of the body, with mainly yellow or orange fins. Look for a blue horizontal streak below the eye. The belly is silvery, the inside of the mouth is white, and the tail edge is almost straight.
The yellow snapper lives in the eastern Pacific from southern California to Peru, though it’s rare north of Baja California. It also reaches the oceanic islands, including Cocos and the Galápagos. It stays close to shelter over rocky bottoms from 3 to 94 m deep. Juveniles are common in estuaries, and the species tolerates fresh water. By day it often schools; at night it hunts fish, shrimp, crabs and mollusks.
Larvae drift for about 23 days before settling near shore. Young fish stay in mangroves until they’re about 10 cm long, then move along rocky shores to reefs; adults of 25 to 60 cm are most abundant on shallow and deep rocky reefs. Near La Paz, fish mature at about 32.6 cm. Off Jalisco, the most mature fish were found from July to October.

Source ↗Reefs within 10 km of a mangrove held about ten times more young yellow snappers than reefs farther away. The farthest one was found 65 km from a mangrove.

Source ↗Ocean eddies carry yellow snapper larvae between the Baja and mainland coasts of the southern Gulf. A genetic study found a single linked population, with some sites supplying young fish to others.
Source ↗Yellow snapper live on rocky reefs, points and banks around Los Cabos year-round. Local reports from San José del Cabo mention good numbers of yellow snapper near shore on rock structure (June 2024), and yellow snapper caught on yo-yo jigs at the Iman and San Luis banks (March 2023).
Drop yo-yo jigs on the banks, or fish live or dead sardines near the bottom close to the rocks. It never strays far from shelter, so when it’s hooked, keep it out of the rocks quickly. Sport fishing is not allowed inside Cabo Pulmo National Park.

The pargo prieto (Lutjanus novemfasciatus) is dark olive-brown to copper red with silvery lower sides and 8 to 9 dusky bars, and it grows far bigger. The Colorado snapper (L. colorado) is mostly dark red with a pink or whitish belly and no yellow. The barred pargo (Hoplopagrus guentherii) has about 6 double brown bars, dark spots on the head and a long tube-shaped front nostril. The mullet snapper or pargo lisa (L. aratus) is grey to greenish, with alternating dark and light stripes along its sides.
How to tell Cabo’s groupers and snappers apart ›
Yes. Pargo amarillo and pargo alazán are Spanish names for Lutjanus argentiventris.
Many spend their first year in mangroves, first on pebble beds and then among red mangrove roots, before moving to rocky reefs.
No. Sport fishing is not allowed in Cabo Pulmo National Park.
