TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Rodentia
Family: Muridae
Genus/species: Mus musculus

GENERAL CHARACTERISTICS: it has a dull greyish-brown fur and the tail, which is the same length as the body, It has a
distinctive strong ‘stale’ odor. Length: 6 – 10 cm (2.36 – 4 inches)

IMG_8925 (1)

DISTRIBUTION/HABITAT: Global, origin probably Mediterranean

DIET: House mice are typically active at night eating invertebrates, most human food and more.

IUCN Red List Least Concern (LC)

REMARKS: The House Mouse is partially color blind communicating with squeaks, ultrasonic calls and pheromones.

Predators such as pit vipers, boas and pythons have heat sensing organs which detect infrared wavelengths on their face. This feature that detects heat is used in the dark to detect warm-blooded prey such as mice.

M. musculus is one of the most widely distributed and successful mammals in the world.

 Blackeye Goby3156957770_6f372fc8f5_b

GENERAL CHARACTERISTICS: Eye and tip of first dorsal fin black. Large scales. Fleshy ridge extending from area between the eyes to dorsal fin. Pale tan overall with small blue spot below the eye. Max. length: 15 cm (6 inches).

 Blackeye Goby3968321166_3e2284847f_b

DIET IN THE WILD: Small crustaceans and mollusks including amphipods, copepods, isopods, decapods (particularly hermit crabs), snails, and clams.

Blackeye Goby3707835699_7a6d5047ff_b

REPRODUCTION: A protogynous hermaphrodite (born female and change sex to male). Forms permanent harem groups composed of a single male and several smaller females Oviparous, Male cleans spawning site under rock, then attracts female by rising from bottom to display his black pelvic disk. Male guards nest after female lays eggs.

CONSERVATION: Not Evaluated

REMARKS: Defensive strategy is to freeze on the bottom but if a predator comes too close, the goby dashes for safety under a rock or to another protective spot.

 Rubberlip Surfperch14903173973_a0105891ee_k

GENERAL CHARACTERISTICS: Silvery blue to purplish on dorsal surface; pectoral fins yellowish; pelvic fins black or dusky fringed with black; prominent lips thick, pink or white. The lower jaw is slightly shorter than the upper. Juveniles have one or two vertical dusky bars on the body, usually are not found on adults.The largest of the surfperches, up to 19 inches long.

REPRODUCTION: Like all surfperches, they are viviparous with young highly developed and free-swimming at birth.

CONSERVATION: IUCN: Not evaluated.

REMARKS: Overall population decline. Small commercial fishery in Southern California; most caught by sport fishermen who seek out the larger, mature females.

 RedtailSurfperch14869151163_0bb09c1cd1_k

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. Max. size: 41 cm (16 in) and 2.1 kg (4.5 lbs.) in weight.

RedtailSurfperch6764336841_65e83d9bbe_b 

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

DIET IN THE WILD: Worms, crabs, other small crustaceans, and fishes.

LONGEVITY: Life span: up to 9 years.

REPRODUCTION: Females viviparous and reproductively mature at 3–4 years; males mature at 2 years. 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.

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. Max. size: 30 cm (12 in).

 RainbowSurfperchIMG_8307

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: Isopods, amphipods and other crustaceans; also snails and brittle stars.

 REPRODUCTION:  The male approaches the female from below; both swim with vents close for 2 or 3 seconds, then separate and repeat the process. As all surfperchs fertilization is internal and 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).

(content.cdlib.org/view?docId=kt2f59n5cq;NAAN=13030&do…)

 MORTALITY/LONGEVITY: Life span: to 9 years.

 CONSERVATION: IUCN: Not evaluated.

REMARKS: S. serriceps is an important species in both the nearshore recreational fishery and in the commercial live fish fishery.

Serriceps means “saw head” in latin, referring to the large head spines. See below.

ClepticusParrae14582664694_eb0ac408f1_b

GENERAL/CHARACTERISTICS: Color primarily violet or purple; large individuals with a wash of yellow on lower two-thirds of body; prolonged portions of dorsal and anal fins and tips of pelvic fins blackish. Max length : 30.0 cm (1 foot).

DISTRIBUTION/HABITAT: Western Atlantic: Bermuda, southern Florida (USA), and Bahamas to northern South America. Found in seaward reef slopes; occasionally on shallow patch reefs.
Depth 10-30 meters (33-100feet).

DIET IN THE WILD: Plankton small jellyfishes, pteropods, pelagic tunicates and various invertebrate larvae

REPRODUCTION: Form leks during breeding (a place where males assemble during the mating season and engage in competitive displays that attract females). Protogynous hermaphrodite The largest fish in a group is a dominant breeding male, while smaller fish remain female. If the dominant male dies, the largest female changes sex.

CONSERVATION: IUCN; Least Concern.

REMARKS: Like many wrasse, it changes color markedly during its lifetime, with juveniles being almost completely violet-purple. As it matures, it develops a yellow patch on the rear part of its body.
