Migration

Alien species

De glanzende bolzakpijp Aplidium glabrum is oorspronkelijk afkomstig uit koude tot Arctische contreien. Het is een kolonievormende soort met een opvallend sponsachtig uiterlijk. De kolonies hebben de vorm van korstige klompen, zijn ietwat doorschijnend en kunnen grijs, geel tot zelfs oranje gekleurd zijn. Aan onze kust is de glanzende bolzakpijp sinds 2000 terug te vinden in de Zeebrugse jachthaven, waar ze groeit op touwen, kades, pontons en andere harde substraten.

Alien species

Originally, the ascidian Aplidium glabrum only occurred in cold to Arctic regions. It is a colony forming ascidian with a spongy appearance. The colonies are shaped as crusty lumps, are somewhat transparent and can be grey, yellow or even orange. On the Belgian coast, since 2000, the species is found in the marina of Zeebrugge, where it grows on ropes, quays, pontoons and other hard substrates.
