TAXONOMY
Kingdom: Animalia
Phylum:  Chordata

Order: Perciformes (Perch-likes)
Suborder: Labroidei
Family: Embiotocidae (surfperches)

Genus/species: Rhacochilus vacca

 PilePerchIMG_0091

DIET IN THE WILD: R. vacca feed on hard-shelled mollusks, crabs and barnacles. 

REPRODUCTION: Fertilization is internal. Viviparous (live bearer). Fecundity increases with age, averaging from 11–60 young.

LONGEVITY: 7–10 years.

CONSERVATION: Least Concern, the distribution of this species may coincide with a number of designated marine protected areas.

REMARKS: Specialized pharyngeal dentition enable the pile perch to crush hard shells persuading some ichthyologists to place the species in its own genus (Damalichthys).

TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Perciformes
Family: Embiotocidae (Surfperches)

Genus/species: Amphistichus rhodoterus

 GENERAL CHARACTERISTICS: The body of the Redtail Surfperch is a deep oval shape and is compressed from side to side. All fins reddish or pink. Faded brown bars on the side. Silvery overall with pale olive shading above and 9 to 11 narrow vertical dark bars, posteriorly, broken and staggered along the lateral line. Caudal (tail) fin broadly forked; dorsal fin distinctive for the long dorsal spines that contrast with shorter soft rays.

Length up to: 41 cm (16 in) and 2.1 kg (4.5 lbs.) in weight.

 

DISTRIBUTION/HABITAT: Temperate marine. Vancouver Island to Monterey Bay around sand beaches and rocky shores in surf.

DIET IN THE WILD:  A. rhodoterus feeds on worms, crabs, other small crustaceans, and fishes.

LONGEVITY: Life span: up to 9 years.

REPRODUCTION: The Redtail Surfperch females are viviparous and reproductively mature at 3–4 years; males mature at 2 years. The females enter bays and estuaries to spawn.

REMARKS: This shallow water schooling surfperch is most often caught from central California northward.  A. rhodoterus omprises 10–30% of the total recreational catch in this area. Redtails also support a sizable commercial fishery, and comprise almost 75% of the commercial surfperch catch.

TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Family: Embiotocidae (Surfperches)

Genus/species: Hypsurus caryi

 GENERAL CHARACTERISTICS: Compressed and oval to oblong-shaped bodies. Orange and blue horizontal stripes on body; larger orangish bars on back. Fins tinged with orange with black blotch on continuous soft dorsal and anal fins. The caudal (tail) fin is forked. 

Length up to: 30 cm (12 in)

DISTRIBUTION/HABITAT: Subtropical. Cape Mendocino to northern Baja California along rocky shores, often at the edges of kelp beds; occasionally over sand but not found in the surf zone.

DIET IN THE WILD: Rainbow Surfperch feed on isopods, amphipods and other crustaceans; also snails and brittle stars.

REPRODUCTION: H. caryi males approach the female from below; both swim with vents close for 2 or 3 seconds, then separate and repeat the process. As with all surfperches fertilization is internal and they are viviparous (livebearers) giving birth to as many as 22 young which are fully-formed (5 cm) at birth miniature versions of the adults.

 CONSERVATION: IUCN: Not evaluated.

 REMARKS: Divers in Monterey Bay report Rainbow Surfperch cleaning ocean sunfish (Mola mola).

TAXONOMY:
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Gasterosteiformes (sea horsespipefishes)
Family: Syngnathidae  (seahorses, the pipefishes, the pipehorses, and the leafyruby, and weedy seadragons all have fused jaws)

Genus/species: Hippocampus ingens

GENERAL CHARACTERISTICS: Their color is variable and can change their body color, depending on the environment. Body colors include maroon, yellow, and muddled brownish-green. adults have thin close set scrubby lines along the head and body.
The tail prehensile and flexible and able to coil around seagrass and other objects.

Length up to 12 inches long.

DISTRIBUTION:HABITAT: Southern California to Peru including the Galapagos Islands. Found on temperate reefs clinging to sponges, branching coral, sea-whips and inhabits weed beds, usually at depths of 1—20 m (3.28-65 ft).

DIET IN THE WILD: Small shrimp, mysids and other plankton. Seahorses lack teeth and jaws instead suck prey through their tube-like snouts.

REPRODUCTION: H. ingens males and females perform a mating “dance” by bobbing up and down together lasting for three days. Finally, a male will display his empty breeding pouch, which the female will fill with eggs using her ovipositor. Males carry fertilized eggs in a brood pouch for 2-3 weeks up and then releases up to 1000 hatched individuals.

LIFESPAN: Estimated range is 3-5 years. The Pacific Seahorse’s camouflage abilities are its best defense to avoiding predation.

PREDATORS: Pacific Seahorses are also known to be associated with flotsam as it has been collected at the surface and from the stomachs of the Pacific Yellowfin Tuna and Bluefin Tuna.

CONSERVATION: IUCN: Vulnerable
Declines result from targeted catch, incidental capture, and habitat degradation from coastal development. Once caught, H. ingens are used throughout Latin America for curios, occasionally in traditional medicine, and in the live aquarium trade. The vast majority are exported internationally for use in traditional medicine.

REMARKS: Academy individuals were captive raised in the Cabrillo Aquarium, Cabrillo, CA.
