The spinner dolphin is a small dolphin found in off-shore tropical waters around the world. It is famous for its acrobatic displays in which it rotates around its longitudinal axis as it leaps through the air. It is a member of the family Delphinidae of toothed whales.
Calamus is a genus of marine ray-finned fishes belonging to the family Sparidae, the seabreams and porgies. Most of the species in this genus are found in the Western Atlantic Ocean, with 2 species occurring in the Eastern Pacific Ocean.
The California spiny lobster is a species of spiny lobster found in the eastern Pacific Ocean from Monterey Bay, California, to the Gulf of Tehuantepec, Mexico. It typically grows to a length of 30 cm (12 in) and is a reddish-brown color with stripes along the legs, and has a pair of enlarged antennae but no claws. The interrupted grooves across the tail are characteristic for the species.
Porcelain crabs are decapod crustaceans in the widespread family Porcellanidae, which superficially resemble true crabs. They have flattened bodies as an adaptation for living in rock crevices. They are delicate, readily losing limbs when attacked, and use their large claws for maintaining territories. They first appeared in the Tithonian age of the Late Jurassic epoch, 145–152 million years ago.
Petrolisthes is a genus of marine porcelain crabs, containing these extant species:
Scarus is a genus of parrotfishes. With 52 currently recognised extant species, it is by far the largest genus in this family. The vast majority are found at reefs in the Indo-Pacific, but a small number of species are found in the warmer parts of the eastern Pacific and the western Atlantic, with a single species, Scarus hoefleri in the eastern Atlantic. Most are very colourful, and have strikingly different initial and terminal phases. Adults of most species reach maximum lengths of between 30 and 50 cm (12–20 in), but the rainbow parrotfish can grow to lengths of 1.2 m (3.9 ft).
Petrolisthes eriomerus is a species of marine porcelain crab found in the eastern Pacific Ocean. It is commonly known as the flattop crab. It is a flattened, rounded animal, with a carapace up to 20 mm (0.8 in) across. It is a filter feeder, and also sweeps food from rocks.
Allopetrolisthes spinifrons is a species of porcelain crab. It displays "hypercarcinisation", whereby the resemblance to a true crab is enhanced by sexual dimorphism of the abdomen. It lives along the Pacific coast of Peru and Chile, as a symbiont of a sea anemone.
Petrolisthes armatus, the green porcelain crab, is a species of small porcelain crab in the family Porcellanidae. It is believed to be native to Brazil but has spread to other parts of the world. Populations in the south eastern part of the United States have increased dramatically and the species is considered to be an invasive species.
Chlorurus is a genus of parrotfish from the Indian and Pacific Oceans.
John Ernest "Jack" Randall was an American ichthyologist and a leading authority on coral reef fishes. Randall described over 800 species and authored 11 books and over 900 scientific papers and popular articles. He spent most of his career working in Hawaii. He died in April 2020 at the age of 95.
Opisthopatus cinctipes is a species of velvet worm in the Peripatopsidae family. This species has 16 pairs of legs, all with claws and all used for walking. The color of the dorsal surface varies from blue to olive green. Females range from 7 mm to 50 mm in length, whereas males range from 6 mm to 36 mm. Like other velvet worms in this genus, this species exhibits matrotrophic viviparity, that is, mothers in this genus retain eggs in their uteri and supply nourishment to their embryos, but without any placenta. The type locality is in South Africa.
Opisthopatus highveldi is a species of velvet worm in the family Peripatopsidae. This species is a clade in the O. cinctipes species complex. This species has 16 pairs of legs and varies in color from brown to black to indigo. The original description of this species is based on two holotypes ranging from 16 mm to 17 mm in length. Also known as the Highveld velvet worm, this species is found in indigenous forest patches along the Highveld in Mpumalanga province in South Africa.
Opisthopatus kwazululandi is a species of velvet worm in the family Peripatopsidae. This species is part of the O. cinctipes species complex. This species has 16 pairs of legs. The color of its dorsal surface varies from brown to rose pink, and the ventral surface ranges from light brown to creamy white. The original description of this species is based on a male holotype measuring 16 mm in length and a female holotype measuring 22 mm in length. Also known as the coastal velvet worm, this species is found in Eastern Cape province and Kwazulu-Natal province in South Africa.
Opisthopatus swatii is a species of velvet worm in the family Peripatidae. This species is a clade in the O. cinctipes species complex. This species has 16 pairs of legs, and the color of the dorsal surface ranges from blue to slate black, while the ventral surface ranges from light brown to creamy white. The original description of this species is based on male holotypes ranging from 13 mm to 20 mm in length. Also known as the Swati velvet worm, this species is found in indigenous forest patches along the Highveld in Mpumalanga province in South Africa.
The crucifix sea catfish — also known as the Christfish, the crucifix/crucifex catfish, the crucifixfish, or the gillbacker, — is a species of catfish in the family Ariidae.
Atyoida is a genus of freshwater shrimp in the family Atyidae. There are five species in the genus, each endemic to a different Pacific island group. The type species, Atyoida bisulcata, is endemic to Hawaiʻi and described by John Witt Randall in 1840.
Petrolisthes cabrilloi, also known as the Cabrillo porcelain crab, is a species of crab. Native to the Pacific coast of North America, it was first described to science by Steve Glassell in 1945. Its range is believed to be from Morro Bay to Baja California. It is more common than its close cousin Petrolisthes cinctipes in waters south of Point Conception.
