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.

Genus/Species Neoclinus uninotatus

GENERAL CHARACTERISTICS: The color is usually light to dark brown with black specks and mottling. The jaw is large extending beyond the eye. There is one large ocellus (eye spot) between dorsal fin spines. A few carrier above the eye and one larger (longer than the eye diameter).

DISTRIBUTION/HABITAT: N. uninotatus is found along the California coast from Bodega Bay to the Baja California. It is usually found in rock crevices as well as inside objects, including bottles, cans, and tires which it guards fiercely.
Depth 3-27 m (10-90 ft)
Length up to 25 cm (10 in)

DIET IN THE WILD: Benthic crustaceans

REPRODUCTION: Both sexes guard the eggs with the male circulating water over them.

CONSERVATION: IUCN Least Concern.

REMARKS: The Sarcastic Fringhead is similar but has two ocelli on the dorsal fin.

TAXONOMY
Kingdom: Animalia
Phylum: Mollusca
Class: Cephalopoda
Order: Octopoda
Family: Octopodidae

Genus/species: Octopus bimaculoides

GENERAL CHARACTERISTICS: Usually a mottled-brown color with a dark deep-blue ovoid spot under each eye. It can use the chromatophores in its skin to change its color and texture when hunting for prey or hiding from predators (including its eye spots).

Size to 3 feet (including its body and outstretched arms)

DISTRIBUTION/HABITAT: Found from central California to northern Baja California among reefs and pilings on the sea floor.

DIET IN THE WILD: Limpets, black abalone, snails, clams, hermit crabs and small fishes. Prey are subdued with a parrotlike beak and toxic secretions through a salivary gland. Their food is then scraped out with a radula.

REPRODUCTION: Females lay up to 150,000 eggs under rocks from late winter to early summer, then brood on them continuously for 2-4 months. During brooding, the female doesn’t feed and usually dies when eggs hatch.

Life Span: One-and-a-half to two years.

PREDATORS: Moray eels, scorpionfish and humans. Arms are often lost during a fight with a moray eel and can regenerate.

CONSERVATION: O bimaculoides is very sensitive to impaired water quality, thus water pollution is an issue for its survival.
