This recent arrival along the North Wales coast was first discovered at Holyhead marina in 2008 by scientists at the School of Ocean Sciences and is said to be a potentially problematic "alien" species as it is highly invasive.
There are more than 2,000 species of sea squirts
, and they are found throughout the world.
"The sea squirts
were gone, and all of a sudden the glass sponges had tripled" in number, Richter says.
, for example, produce an agent that fights skin cancer.
They have found that cellulose from tunicates, commonly known as sea squirts
, can influence the behaviour of skeletal muscle cells in the laboratory.

From the evolutionary standpoint, individuals who play without getting themselves killed are mere likely to reproduce successfully, whether they are sea squirts
(one of the book's examples) or humans.
The thyroid gland, which produces and stores vital thyroid hormones, is introduced as not only the largest endocrine gland but also the oldest phylogenetically; even sea squirts

In a memorandum it explained that should EU ministers back the move, "Greenland can trade these commodities with the Union [as if they were produced within the EU] provided that Greenland transposes EU sanitary and, where appropriate, animal health rules on fishery products, live bivalve molluscs and by-products derived from these sources." The deal would also cover echinoderms (such as sea urchins and sea cucumbers), tunicates (for instance sea squirts
) and marine gastropods (these include whelks, winkles and abalone).
The translucent creatures were sea squirts
, animals that usually feed by pushing seawater through their bodies and filtering out plankton.
