What else is in the sea cucumbers habitat?
Not understanding why “what else” is in the sentence, but sea cucumbers are algal eaters, taking in bottom sand, silt and pebbles, digesting the algal matter on them and pooping back out the sand, now “cleaned”, so to speak. In some instances, if they are taking in sand, or silt, the excrement will look like a strand of pearls. In Hawaii, this is called a “mermaids necklace”.
