Alex Mustard - SLUUURP!
A nudibranch (Flabellina nobilis: Coryphella nobilis) feeding on a solitary hydroid (Tubularia indivisa), note how the hydroid has bent back as it is pulled into the nudibranch’s mouth by one of its tentacles. This photo reminds me of a child (and some adults) eating spaghetti.
Nudibranchs are small, marine gastropod molluscs, which unlike snails have lost their shells. Although they might seem vulnerable to predators, most nudibranchs are very well defended. The nudibranch is not only able to eat the stinging nematocysts of the hydroid without getting stung, but actually uses its prey’s stings for its own defence, storing them primed and ready in the extensions of its gut that branch its the cerata on its back. A prime example of you are what you eat.
