An unusual new fossil discovery of one of the earliest animals on earth may also provide the oldest evidence of muscle tissue – the bundles of cells that make movement in animals possible.
The hard corals primarily responsible for the construction of coral reefs around the world have attracted the attention of taxonomists for hundreds of years.
A deep-water creature once thought to be one of the world's largest sea anemones, with tentacles reaching more than 6.5 feet long, actually belongs to a new order of animals. The finding is part of a new DNA-based study led by the American Museum of Natural History that presents the first tree of life for sea anemones, a group that includes more than 1,200 species.
Sponges are usually considered to be the oldest living animals, having evolved before all other groups.
Researchers from Virginia Tech College of Engineering have created an autonomous robotic jellyfish the size and weight of a grown man.
While many researchers are focused on how physical barriers and isolation can lead to new species on land, a pair of LSU biologists are more interested in the speciation of animals in the ocean.
Nature: Central components of muscles of higher animals much older than assumed
In an article published Wednesday, a team of Navy-sponsored researchers outlined an in-the-works project for a robotic jellyfish that is able to propel itself through water by harnessing the latent power of the ocean.
New research from the University of California shows how the ability to detect light could have evolved before anything like an eye.
A study carried out over 50 years by an international team, with the participation of the Balearic Oceanography Centre of the Spanish Institute of Oceanography (IEO) has confirmed an increase in the size and intensity of proliferations of the jellyfish Pelagia noctiluca.
The Warty Comb Jelly (Mnemiopsis leidyi), also known as the Sea Walnut, is a species of tentaculate ctenophore originally native to the western Atlantic coastal waters. Three species of Mnemiopsis have been named, but are now generally categorized as different ecological forms of the species leidyi. This species tolerates a wide range of salinity (2 to 38 psu), temperature (36 to 90 degrees F), and water quality. This creature was introduced in the Black Sea in the 1980s, where only one...
Chalice Corals, are a family of stony corals in the Pectiniidae family. Members of this family are mostly colonial but at least one species, Echinomorpha nishihirai, is solitary. These corals are endemic to the Indian and Pacific oceans. Pectiniids have a number of different forms but are basically streamlined and smooth. Polyps are large and brightly colored and resemble those of members of the Mussidae family of corals. The polyps are only extended at night. Tentacles are translucent,...
Fungia scruposa is a species of mushroom coral that lives a single individual rather than as a colony. It starts out life as a small disk attached to dead coral or rock, but by the time it reaches about 1 inch in diameter, it becomes detached. The adult has a single polyp that reaches up to 10 inches in diameter. This is the first species of coral that has been observed eating jellyfish. While most of its diet consists of bacteria and mesozooplankton, it does take larger marine life,...
The Black Sea nettle (Chrysaora achlyos) or sometimes known as the Black jellyfish is known for its dark coloration. This species of jellyfish is found in the Pacific Ocean. There have been reports or sighting of the black jellyfish as for north as British Columbia but its range is mostly thought to be from the north in Monterey Bay, to the southern shores of Baja California and Mexico. The Black Sea nettle is quite large. The bell of the jellyfish can measure up to 3 feet in size while...
