TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Family: Serranidae (Sea basses: groupers and fairy basslets)

Sea basses have an elongated body has small scales, with a large mouth, and the tail is generally straight-edged or rounded. The dorsal fin, a diagnostic feature, consists of a forward, spiny section and a hinder, soft-rayed section; the two portions are usually joined but may be separated by a notch.

Genus/species: Paralabrax clathratus

GENERAL CHARACTERISTICS:Pale blotches on back. Brown to olive above and cream below with pale spots along sides.

Length up to 72 cm (28.5in) and 14.5 pounds (6.6 kg)

DISTRIBUTION/HABITAT: Eastern Pacific coast from southern Washington to southern Baja California. Most often found near or in kelp beds or structures of any kind; shallow water usually from about 2.5 (8 ft) to 20 m (65 ft).

DIET IN THE WILD: Juveniles: plankton and small invertebrates, especially crustaceans. Adults: small fishes, octopuses, squid, crabs, shrimps, and algae. Known to form groups to prey on schooling fishes.

REPRODUCTION: Spawn in groups in deep water. Pelagic eggs hatch into larvae, which metamorph into juveniles after approximately a month. The juveniles settle among blades of kelp

MORTALITY/LONGEVITY: Life span: to at least 33 years.

PREDATION: California barracuda, Giant Sea bass

CONSERVATION: IUCN RED LIST LEAST CONCERN

REMARKS: The kelp bass is a fine food fish, and among the most important recreational game fishes in southern California.

Genus/species: Hypoplectrus gummigutta

GENERAL CHARACTERISTICS: Body rich chrome-yellow in color. The snout is black bordered by an iridescent blue. Pectoral fins pigmented. Hamlet “species” are defined primarily on differences in color patterns. They are known to interbreed and hybridize freely with very little consistent genetic differentiation amongst them.

DISTRIBUTION/HABITAT: H. gummigutta is rare and found in the Western Central Atlantic. It is coral reef associated.

CONSERVATION: IUCN: Least Concern (LC)

No known major threat but juveniles are potentially a prey item of the invasive Lionfish.

REPRODUCTION: The Golden Hamlet is a simultaneous hermaphrodite (possesses both male and female sex organs).  Successful spawning requires two individual fish.

Color of Life note: Brightly colored fish seem to jump into your sight. But underwater, these bright colors mingle with those of other fish, reef creatures, and the coral itself, to offer a mixtures of color and patterns in which no one individual stands out. Movement of the anemones and corals in the current also serve to obscure and protect the fish.
