Catostylus tagi is a species of jellyfish from warmer parts of the East Atlantic Ocean and since the 2000s also found in the Mediterranean Sea.[1][2] It is the only member of the family Catostylidae that is found in Europe,[3] and it is a common species in the Tagus estuary in Portugal. [4] It has collagen in its bell which is currently being researched to see if it has biomedical uses as an intercellular matrix. The species is named after the Tagus river.[5]
Description[edit]
Typical Catostylus with chunky appendages and tentacle to go with each. This jellyfish has a sting that causes light pain and a skin rash, but generally poses no serious threat.[3] It is up to 65 cm (26 in) in bell diameter,[6] but a more typical size is 25 cm (10 in) in diameter and 2.5 kg (5.5 lb) in weight.[3] Its colour is variable and can be blue-white, cream, brown, or off-white. The exumbrellar grooves are reddish or purplish brown.[7] C. tagi has gonads along the edge of its stomach in an X shape. It has the octant formation typical of Catostylus jellies, the height of the octants are also variable.
Food[edit]
Eats both zooplankton and phytoplankton, certain crustaceans, small fish, and marine snow.
Biomedical use[edit]
Its bell collagen is currently being researched for use as an intercellular matrix. The collagen is made up of 1/3 glycine and the most of the rest is water and other amino acids, its amino acid content is very small. The collagen is denatured as soon as it reaches 29.9 °C (85.8 °F).
