anudibranchaday:The Spanish Dancer Nudibranch (Hexabranchus sanguineus), is famous for being one of the largest nudibranchs out there- while typically reaching 20 - 30cm, it has been seen growing to be 60cm long! But although this nudibranch is relatively heavy compared to its smaller cousins, it doesn’t let that way it down, as when alerted this nudibranch can swim by contracting and waving its mantle. In fact, this movement it where it gets its name, as the undulations are reminiscent of a spanish dancer moving her dress. Its rhinophores are retractable, and only turns its signature bright red colour as it matures. It feeds on sponges on coral reefs 1 - 50m deep, from the Eastern coast of Africa to Hawaii and Japan! -- source link
