Hi,

Could anyone tell me what this is? Found next to Botrylloides leachii, it looks like another colonial tunicate because I can see a tunic between the white parts. Any help is appreciated.

Maybe Botrylloides diegensis, white form.

Would you be so kind as to give me an indication of this colonial tunicate, also found in the proximity of the others? Thank you very much.

Oh wow,I hadn't noticed the Botrylloides wasn't leachii. Thanks for the info on both!

Hello,

The white ascidian is, for me, Symplegma brakenhielmi (Michaelsen, 1904), https://doris.ffessm.fr/ref/specie/5093

For the botrylloides, may be, an another invasive specie, Botrylloides niger Herdman, 1886, https://doris.ffessm.fr/ref/specie/828
