The red-tailed hawk is a bird of prey that breeds throughout most of North America, from the interior of Alaska and northern Canada to as far south as Panama and the West Indies. It is one of the most common members within the genus of Buteo in North America or worldwide. The red-tailed hawk is one of three species colloquially known in the United States as the "chickenhawk", though it rarely preys on standard-sized chickens. The bird is sometimes also referred to as the red-tail for short, when the meaning is clear in context. Red-tailed hawks can acclimate to all the biomes within their range, occurring on the edges of non-ideal habitats such as dense forests and sandy deserts. The red-tailed hawk occupies a wide range of habitats and altitudes, including deserts, grasslands, coniferous and deciduous forests, agricultural fields, and urban areas. Its latitudinal limits fall around the tree line in the subarctic and it is absent from the high Arctic. Generally it favors varied habitats with open woodland, woodland edge and open terrain. It is legally protected in Canada, Mexico, and the United States by the Migratory Bird Treaty Act.
The South American sea lion, also called the southern sea lion and the Patagonian sea lion, is a sea lion found on the western and southeastern coasts of South America. It is the only member of the genus Otaria. The species is highly sexually dimorphic. Males have a large head and prominent mane. They mainly feed on fish and cephalopods and haul out on sand, gravel, rocky, or pebble beaches. In most populations, breeding males are both territorial and harem holding; they establish territories first and then try to herd females into them. The overall population of the species is considered stable, estimated at 265,000 animals.
The Lessepsian migration is the migration of marine species along the Suez Canal, usually from the Red Sea to the Mediterranean Sea, and more rarely in the opposite direction. When the canal was completed in 1869, fish, crustaceans, mollusks, and other marine animals and plants were exposed to an artificial passage between the two naturally separate bodies of water, and cross-contamination was made possible between formerly isolated ecosystems. The phenomenon is still occurring today. It is named after Ferdinand de Lesseps, the French diplomat in charge of the canal's construction.
Amatitlania sajica, the T-bar cichlid or Sajica cichlid, is a Central American species of cichlid found in freshwater streams and lakes on the Pacific slope of Costa Rica. The fish is tan colored with seven indistinct bars on the body. The third bar is usually prominent and coupled with a dark lateral stripe running from the gill cover results in a horizontal T-shaped mark, hence the common name of T-bar cichlid.
The blackmouth lanternshark is a species of dogfish shark within the family Etmopteridae. This species is part of a subgroup that includes one other species from within the family. It is known to inhabit the benthic zones of the Eastern Indian Ocean and the Arafura Sea. These sharks were first described in a 2002 issue of Cybium: International Journal of Ichthyology, and there is still much unknown about the species.
The ocellated wrasse is a species of wrasse native to the eastern Atlantic Ocean and throughout the Mediterranean Sea, the Black Sea, and the Sea of Azov. It inhabits areas with rocks and eelgrass at depths from 1 to 30 m. It feeds on various marine invertebrates. This species can reach 12 cm (4.7 in) in standard length. It can also be found in the aquarium trade.
The tentacled blenny is a species of combtooth blenny most commonly found in all parts of the Mediterranean Sea, in the Sea of Marmara and the Black Sea, and the east Atlantic near the coast of Portugal, Spain, Canary Islands, and Morocco south to Guinea. This species reaches a length of 15 centimetres (5.9 in) TL. Found in brackish waters, in estuaries or deltas, this demersal fish can be found in the sand at the bottom of the water in light vegetation. The adult males guards a suitable spot, which a few females may visit and deposit their eggs, the males fertilizes the eggs and guards them until they hatch.
The Adriatic sturgeon is a species of fish in the family Acipenseridae. It is native to the Adriatic Sea and large rivers which flow in it of Albania, Greece, Italy, Montenegro, Croatia, Bosnia and Herzegovina and Slovenia. Specimens can be seen in several public aquarium, such the Milan Aquarium, Aquarium Finisterrae, Aquarium of the Po, and Oasis of Sant'Alessio in Lombardy.
Salaria is a genus of fish in the family Blenniidae. It now contains marine species which are found around the Mediterranean Sea and the eastern Atlantic Ocean. Freshwater species were reallocated to Salariopsis in 2022. One species, the peacock blenny, has colonised the northern Red Sea through the Suez Canal, a process knowns as anti-Lesspesian migration.
The butterfly blenny is a small marine blenniid fish of Northern and Western Europe, as well as the Mediterranean Sea and Black Sea and Morocco. It is usually found at a depth of 10–400 metres (33–1,312 ft) down, especially in areas with a rocky floor.
The corkwing wrasse is a species of wrasse native to the eastern Atlantic Ocean from Norway to Morocco and out to the Azores, as well as being found in the Mediterranean Sea and the Adriatic Sea. This species can be found in areas of rock or eelgrass at depths from 1 to 30 m.
Salarias fasciatus, commonly known as the jewelled blenny or lawnmower blenny is a benthic, neritic, marine fish species endemic to Australasia. Despite being known as the lawnmower blenny, due to its propensity to consume algae growth in aquaria, it is principally a detritivore, with plant material making up only about 15% of its diet. The lawnmower blenny camoflauges with its surroundings, even changing color to hide itself from predators.
Ophioblennius atlanticus, also known as the redlip blenny and the horseface blenny, is a species of combtooth blenny, family Blenniidae, found primarily in the western central Atlantic ocean. Redlip blennies can be found in coral crests and shallow fringing reefs. They are highly territorial and attack intruders with two long, sharp canine teeth. The adults are found at depths of 10 to 20 meters, and the eggs are benthic. The adults may reach up to four inches in length when fully grown, and they have large reddish lips, from which they attained their names. Redlip blennies largely feed on algae.
The sphinx blenny is a species of combtooth blenny, and the only species in the genus Aidablennius. It was described by Achille Valenciennes in 1836, originally under the genus Blennius, and was later reassigned under "Aidablennius" by Gilbert Percy Whitley in 1947. It is a subtropical blenny known from Morocco, in the eastern Atlantic Ocean, and also from the Mediterranean and Black Seas. Sphinx blennies inhabit shallow, rocky waters in the littoral zone, with sunlight exposure. They feed primarily on benthic algae, weeds and invertebrates. Sphinx blennies can measure up to 8 centimetres (3.1 in) long in total length.
The Kirk's blenny is a species of combtooth blenny in the genus Alticus. It was described by A. Günther in 1964, originally as a member of the genus Salarias. It is a tropical blenny which is known from the Red Sea, Mozambique, Réunion, the Persian Gulf, and India, in the Indian ocean. Kirk's blennies inhabit waters near the shore, and often spend time out of the water. They are able to breathe air when on land. They are oviparous, and form distinct pairs when mating; they also guard their eggs.

Salaria basilisca is a species of combtooth blenny found in the Mediterranean Sea near Tunisia and Turkey, also in the Adriatic Sea. This species reaches a length of 18 centimetres (7.1 in) TL. It is found among seagrass, sometimes where there is a rocky substrate. The male guards the eggs produced by several females. They are protogynous hermaphrodites with individuals being females while young changing to males later.
The yellow triplefin ,> also known as the Abel's triplefin in South Africa, is a species of triplefin in the genus Enneapterygius. Males in this species can reach a maximum length of 2.5 centimetres.
