An aggressive, invasive aquatic organism that is on the state’s most dangerous species list has been discovered in both Winchester Bay and Coos Bay, and scientists say this “colonial tunicate” – Didemnum vexillum – has serious economic and environmental implications.

The newly sequenced genome of a dainty, quill-like sea creature called a lancelet provides the best evidence yet that vertebrates evolved over the past 550 million years through a four-fold duplication of the genes of more primitive ancestors.

"You can eat your relatives but not your friends," could be the off-kilter credo of a tiny marine invertebrate called a sea squirt that can physically merge with, and parasitize, its own kin. The trigger for this unseemly behavior has now been traced to a single gene, isolated by researchers at the Stanford University School of Medicine. That gene also points to a common origin with the vertebrate immune system, far back in animal evolution, potentially shedding light on the development of...

Vase Tunicate, Ciona intestinalis
2014-01-12 00:00:00

The Vase Tunicate (Ciona intestinalis) is a species of sea squirt widely distributed in Northern European waters. It has also spread to other parts of the world, where it is considered invasive. It grows in dense aggregations on any floating or submerged substrate, especially on artificial structures like pilings, aquaculture gear, floats and boat hulls. It is found in the lower intertidal and subtidal zones. Sea squirts have been long recognized as being possibly the closest invertebrate...

Sea Pineapple, Halocynthia roretzi
2014-01-12 00:00:00

The Sea Pineapple (Halocynthia roretzi) is an edible species of tunicate. It is known as the Meongge in Korea and the Hoya or Maboya in Japan. This creature lives in shallow water, usually attached to rocks and artificial substrate. It is adapted to cold water temperatures between 36 and 75 degrees Fahrenheit, but prefer temperatures close to 54 degrees F. This creature is known for both its peculiar appearance, described by journalist Nick Tosches as “something that could exist only in...

Phallusia nigra
2014-01-12 00:00:00

Phallusia nigra is a species of sea squirt (tunicate) found in tropical seas around the world. It is usually found in shallow waters attached to any hard substrate. It is a solitary animal rather than living in colonies. Although the native range of this animal is unknown, the tropical western Atlantic Ocean, the Red Sea and the Indian Ocean are possibilities. Like all ascidians, this species has a thick leathery envelope (tunic) containing cellulosic material. The tunic encloses a...

Painted Tunicate, Clavelina picta
2014-01-12 00:00:00

The Painted Tunicate (Clavelina picta) is a species of sea squirt (tunicate) in the genus Clavelina (known as “little bottles.”). It is found in the waters of Florida, the Bahamas, and the Caribbean. It often occurs in large clusters attached to black coral, sponges, and gorgonians. Colonies may contain hundreds of individuals. This animal, like all ascidians, is a sessile filter feeder. It is about 0.75 inches long and comes in a variety of colors, including reds, purples and yellows....

Red-sea Squirt, Halocyntia papillosa
2014-01-12 00:00:00

The Red-sea Squirt (Halocyntia papillosa) is a species of sea squirt (tunicate) that are sometimes referred to as sea peaches. It is found in the Northeast Atlantic and Western Pacific oceans, along the Portuguese coast and in the Mediterranean Sea. It attaches itself to rocks and overhangs and occurs at depths of 6 to 325 feet. The Red-sea Squirt is generally about 4 inches high, but can reach maximum lengths of 8 inches. It contracts when disturbed. It is ovoid in form with a granulous...
