LONGEVITY: Live up to 25 years

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 on this immature Treefish.

TAXONOMY

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 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.

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.

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.
