WThe giant damselfish inhabit rocky reefs, below the surf zone at depths of 1–25 m. They feed mainly on low-profile, attached algae. They defend both feeding and reproductive territories by driving off other fishes and divers who come too close. They are oviparous, and form distinct pairings during breeding. The eggs are demersal and adhere to the substrate. Males guard and aerate the eggs.

It is found in tropical and subtropical waters in the eastern Pacific Ocean, from Mexico to Peru, and possibly as far north as the Gulf of California. It frequents inshore habitats over soft bottoms to a depth of 100 m, and also enters mangroves and estuaries.
WThe threadfin jack or thread pompano is a species of coastal marine fish in the jack family Carangidae. The species inhabits the tropical waters of the eastern Pacific Ocean from Baja California in the north to Ecuador and the Galapagos Islands in the south. It is a moderately large fish, growing to 60 cm (24 in) and may be recognized by its filamentous dorsal and anal fin lobes. The threadfin jack inhabits both deeper coastal waters and inshore environments, including reefs and estuaries, where it preys on minute benthic and pelagic organisms, including small fishes and crustaceans. Very little is known about the ecology and reproductive cycle in the species. The threadfin jack is of importance to fisheries throughout its distribution, caught by hook-and-line and net methods and marketed fresh and salted, and is considered a very good table fish. The species was named Carangoides dorsalis by Theodore Gill 20 years before the name Caranx otrynter was introduced, but confusion with Vomer dorsalis led to the proposal of the new name to separate the two species.
WThe kelp pipefish, Syngnathus californiensis, is a species of the pipefish. It inhabits the eastern Pacific from the Bodega Bay in northern California, United States, to southern Baja California, Mexico. It is a marine subtropical demersal fish, up to 50 centimetres (20 in) length.
WThe Pacific jack mackerel, also known as the Californian jack mackerel or simply jack mackerel, is an abundant species of pelagic marine fish in the jack family, Carangidae. The species is distributed along the western coast of North America, ranging from Alaska in the north to the Gulf of California in the south, inhabiting both offshore and inshore environments. The Pacific jack mackerel is a moderately large fish, growing to a maximum recorded length of 81 cm, although commonly seen below 55 cm. It is very similar in appearance to other members of its genus, Trachurus, especially Trachurus murphyi, which was once thought to be a subspecies of T. symmetricus, and inhabits waters further south. Pacific jack mackerel travel in large schools, ranging up to 600 miles offshore and to depths of 400 m, generally moving through the upper part of the water column.
WAbudefduf troschelii, the Pacific sergeant major or Panama sergeant major, is a species of damselfish belonging to the family Pomacentridae that can be identified by their pronounced black stripes on the lateral sides of the fish. Its specific name honors the zoologist Franz Hermann Troschel (1810-1882). It is native to the neritic pelagic zone of the shallow water coral reefs in the Eastern Pacific Ocean and they are an omnivorous species feeding on plankton and algae attached to their coral habitat. Abudefduf troschelii is a sister-species of A. saxatilis but have diverged from each other since the uplift of the isthmus of Panama, separated by the rise of the Panama land bridge 3.1 to 3.5 million years ago. Males, like in many other marine species, take care of and defend newborn A. troschelii after they have been hatched by eggs from the female. There are currently no major threats to the species and there is no indication of a current decline in its population size. The IUCN Red List lists this damselfish as being of “least concern”.

It has a cylindrical trunk, conical head, and small spiracles behind the eyes. The snout of the Mexican hornshark is very round and blunt. Like all members of the order Heterodontiformes, this shark has fin spines in front of both of its dorsal fins. The first dorsal fin originates before the pectoral fins, while the second dorsal fin originates behind the pelvic fins.

It generally inhabits sandy flats, rocky reefs, and kelp forests from the surface to a depth of 200 m (660 ft), but has also been known to make forays into the open ocean. Measuring up to 1.4 m (4.6 ft) long, this species has smooth-rimmed spiracles and a dark gray, slate, or brown dorsal coloration, sometimes with dark spots. Its body form is typical of the genus, with a rounded pectoral fin disc wider than long and a thick tail bearing two dorsal fins of unequal size and a well-developed caudal fin.

The specific epithet entemedor seems to be the Spanish equivalent of "intimidator".
WThe scoophead is a little-known species of hammerhead shark, part of the family Sphyrnidae. It inhabits the tropical waters of the western Atlantic Ocean, from Panama to southern Brazil, and in the eastern Pacific Ocean from the Gulf of California to Ecuador, and probably northern Peru, as well.

Despite its name and appearance, it is more closely related to electric rays than to true guitarfishes of the family Rhinobatidae. This species ranges from Tomales Bay to the Gulf of California, generally in inshore waters no deeper than 6 m (20 ft). It can be found on or buried in sand or mud, or in and near kelp beds. Reaching 91 cm (36 in) in length, the thornback guitarfish has a heart-shaped pectoral fin disc and a long, robust tail bearing two posteriorly positioned dorsal fins and a well-developed caudal fin.
