Hyas may also refer to:
Hyas, in Greek mythology, was a Boeotian who was regarded as the ancestor of the ancient Hyantes (Ὕαντες), who were the aboriginal inhabitants of Boeotia. His name means rain from hyô, hyetos.
Sigma Hydrae, also named Minchir, is a solitary star in the equatorial constellation of Hydra. It is visible to the naked eye with an apparent visual magnitude of 4.48. The estimated distance to this star from the Sun, based upon an annual parallax shift of 8.75 mas, is around 370 light-years. At that distance, the visual magnitude of the star is diminished by an interstellar extinction factor of 0.16, due to intervening dust.
The great spider crab, Hyas araneus, is a species of crab found in northeast Atlantic waters and the North Sea, usually below the tidal zone.
Delta Hydrae, Latinized from δ Hydrae, is a double star in the equatorial constellation of Hydra. It is visible to the naked eye with an apparent visual magnitude of 4.146. Based upon an annual parallax shift of 20.34 mas, it is located about 160 light years from the Sun.
Zeta Hydrae is a solitary star in the equatorial constellation of Hydra. This is a generally faint constellation, so, at an apparent visual magnitude of +3.10, this is the third-brightest member after Alphard and Gamma Hydrae.
The Bayer designation Tau Hydrae is shared by two star systems in the equatorial constellation of Hydra. The two stars are separated by 1.74° in the sky.
The Majoidea are a superfamily of crabs which includes the various spider crabs.
Hya or HYA may refer to:
Decorator crabs are crabs of several different species, belonging to the superfamily Majoidea, that use materials from their environment to hide from, or ward off, predators. They decorate themselves by sticking mostly sedentary animals and plants to their bodies as camouflage, or if the attached organisms are noxious, to ward off predators through aposematism.
Inachus dorsettensis, commonly known as the scorpion spider crab, is a species of crab generally found on loose substrates from 6 metres (20 ft) depth down to about 100 m (330 ft).
Hyas is a village in the Canadian province of Saskatchewan within the Rural Municipality of Clayton No. 333 and Census Division No. 9.
Hya is an Afro-Asiatic language spoken in northern Cameroon and neighboring regions of Nigeria.
Hyas is a genus of oregoniid crabs comprising five extant species:
The Oregoniidae are a family of crabs, formerly included in the family Majidae. It contains the four genera Chionoecetes, Hyas, Macroregonia, and Oregonia.
Around 65 species of crab occur in the waters of the British Isles. All are marine, with the exception of the introduced Chinese mitten crab, Eriocheir sinensis, which occurs in fresh and brackish water. They range in size from the deep-water species Paromola cuvieri, which can reach a claw span of 1.2 metres, to the pea crab, which is only 4 mm (0.16 in) wide and lives inside mussel shells.
The Bayer designation υ Hydrae is shared by two stars in the constellation of Hydra:
Eta Hydrae is a star in the equatorial constellation of Hydra. With an apparent visual magnitude of 4.3, it is visible to the naked eye. However, it is the faintest of the five stars that form the "head" of the hydra. Based upon an annual parallax shift of 5.56 mas, it is located roughly 590 light years from the Sun.
Rho Hydrae, equally written ρ Hydrae, is a binary star in the equatorial constellation of Hydra. It is visible to the naked eye with an apparent visual magnitude of 4.34. The distance to this system, based upon an annual parallax shift of 9.21 mas, is about 354 light years. At that distance, the visual magnitude is diminished by an interstellar extinction of 0.06 magnitudes, due to intervening dust.
Hyas coarctatus is a marine crab species native to the North Atlantic. It is characterized by a lyriformed shell.
