A sea cucumber can be hard to figure out at the best of times. A long red blob with orange spikes, they can be difficult to make heads or tails of, and for good reason.
To show how a cucumber is actually different from one end to the other I managed to snap these videos of a giant red cucumber feeding. Located at the ‘head’ of the animal these fluffy pink flowers known as feeding tentacles comb through sand for bits of detritus, making them important cleaners for the ocean floor. On their other end cucumbers breath through their butt, which can also be used as a second mouth for suspension feeding! Eating with both ends is known as bipolar feeding, and in the animal kingdom it is not as uncommon as you might hope.
From mouth to, er, other mouth, these animals are full of surprises!
