Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals. It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth.
A seahorse is any of 46 species of small marine fish in the genus Hippocampus. "Hippocampus" comes from the Ancient Greek hippókampos (ἱππόκαμπος), itself from híppos (ἵππος) meaning "horse" and kámpos (κάμπος) meaning "sea monster" or "sea animal". Having a head and neck suggestive of a horse, seahorses also feature segmented bony armour, an upright posture and a curled prehensile tail. Along with the pipefishes and seadragons they form the family Syngnathidae.
The leafy seadragon or Glauert's seadragon, is a marine fish. It is the only member of the genus Phycodurus in the family Syngnathidae, which includes seadragons, pipefish, and seahorses.
The Syngnathidae is a family of fish which includes seahorses, pipefishes, and seadragons. The name is derived from Ancient Greek: σύν, meaning "together", and γνάθος, meaning "jaw". The fused jaw is one of the traits that the entire family have in common.
The common seadragon or weedy seadragon is a marine fish related to the seahorses. Adult common seadragons are a reddish colour, with yellow and purple markings; they have small leaf-like appendages that resemble kelp fronds providing camouflage and a number of short spines for protection. Males have narrower bodies and are darker than females. Seadragons have a long dorsal fin along the back and small pectoral fins on either side of the neck, which provide balance. Common seadragons can reach 45 cm (18 in) in length.
Male pregnancy is the incubation of one or more embryos or fetuses by organisms of the male sex in some species. Most species that reproduce by sexual reproduction are heterogamous—females producing larger gametes (ova) and males producing smaller gametes (sperm). In nearly all animal species, offspring are carried by the female until birth, but in fish of the family Syngnathidae, males perform that function.
Pipefishes or pipe-fishes (Syngnathinae) are a subfamily of small fishes, which, together with the seahorses and seadragons, form the family Syngnathidae.
Underwater World, also known as Underwater World Singapore Pte Ltd, was an oceanarium located on the offshore Singaporean island of Sentosa. It was opened on 13 May 1991 and closed on 26 June 2016.
Ruby is a color that is a representation of the color of the cut and polished ruby gemstone and is a shade of red or pink.
The Hippocampinae are a subfamily of small marine fishes in the family Syngnathidae. Depending on the classification system used, it comprises either seahorses and pygmy pipehorses, or only seahorses.
Altona Beach is a beach located in Altona, Victoria, Australia. A long pier is located towards the middle of the beach. From late November through to around Easter each year, volunteers from the Altona Lifesaving Club patrol the beach on the eastern side of the pier.
William Buelow Gould was an English and Van Diemonian (Tasmanian) painter. He was transported to Australia as a convict in 1827, after which he would become one of the most important early artists in the colony, despite never really separating himself from his life of crime.
The Greater Cleveland Aquarium is an aquarium in Cleveland, Ohio. Occupying the historic FirstEnergy Powerhouse building located on the west bank of the Cuyahoga River in the city's Flats district, the aquarium, which opened in January 2012, consists of approximately 70,000 square feet (6,500 m2) of exhibition space and features 55 exhibits over 9 thematic concentrations representing both local and exotic species of fish. The facility is the only independent, free-standing aquarium in the state of Ohio and ended a 26-year period that the city lacked a public aquarium.
The ribboned pipefish, ribboned pipehorse or ribboned seadragon, is a species of pipefish found along the coast of northern Australia and New Guinea in habitats ranging from shallow and weedy to deeper and sandy bottoms down to depths of 16.5 m (54 ft). This species grows to a total length of 30 cm (12 in). Their colors can range from greenish yellow to brownish red. This species is the only known member of its genus.
Established in 1976, the Marine Life Society of South Australia is a long-standing incorporated association which aims to foster the study and appreciation of marine life and encourage marine conservation engagement in South Australia. The society's most notable recent achievement was the statewide protection of all Syngnathidae under the State's Fisheries Management Act. This was driven by concerns that the animals could become targeted by aquarium keepers and poachers looking to exploit the species for the aquarium trade.
The ruby seadragon is a marine fish in the family Syngnathidae, which also includes seahorses. It inhabits the coast of Western Australia. The species was first described in 2015, making it only the third known species of seadragon, and the first to be discovered in 150 years. A specimen found on shore in 2007 was 23.5 cm (9.3 in) long.
Frank Edward Clarke was a New Zealand ichthyologist and scientific illustrator. He discovered numerous fish species previously unknown to science and was the third most active describer of those new species in New Zealand from 1870 to 1905. Clarke was also an artist and a collection of his scientific illustrations is held at Museum of New Zealand Te Papa Tongarewa.
The Great Southern Reef is a system of interconnected reefs that spans the southern coast of continental Australia and Tasmania and extends as far north as Brisbane to the east and Kalbarri to the west. It covers 71,000 km2 (27,000 sq mi) of ocean and straddles five states, running along the coast for 8,000 km (5,000 mi).
Nerida Gaye Wilson is an invertebrate marine molecular biologist at the Western Australian Museum who has interests in diversity, systematics, phylogeny, phylogeography and behavior. Wilson has been instrumental in demonstrating the level of marine cryptic species complexes in Antarctic waters, testing the circumpolar distribution paradigm with molecular data, and using interdisciplinary approaches to show how Antarctic diversity may have been generated. Her work with NOAA on Antarctic Marine Living Resources has been used to regulate exploratory benthic fisheries.
Leafy seadragons are widely recognized for their strikingly derived characters, including leaf-like appendages, extreme spinal curvature, elongated craniofacial bones, and large body size. These make them phenotypic outliers in the teleost fish clade . Up until recently, the genome of leafy seadragons was unknown; but in 2022, their genome was fully annotated, along with weedy seadragons. Several significant features have been found in the leafy seadragon and weedy seadragon genomes, including divergent noncoding regions near a developmental gene responsible for integumentary growth; high genome wide repetitive DNA density; and recent transposable element expansions. Genetic diversity in leafy seadragons and weedy seadragons is relatively low as they have low-dispersal life history. Most recently, another species of seadragon was discovered and genetically sequenced: the ruby seadragon, which differs genetically and phenotypically from the two other seadragon species.
