“The food particles a bdelloid ingests pass thru its jaws, called the trophi and which happen to be the only hard parts in their bodies.”
“That's surprising -- the trophi can be preserved, though, right?”
“The trophi can be preserved, but they are not by themselves enough to identify species.”
“The picture below shows the trophi of this unidentified species of bdelloid.”
“Buccal appendages: the mouth parts excluding the labrum: see trophi.”
“Mouth-parts: a collective name including labrum, mandibles, maxillae, labium and appendages = trophi.”
“Abdomen yellowish brown, above sprinkled with dark brown, the edges of each segment with several small wart-like prominences; two first segments being also shagreened at the sides, beneath pitchy brown, segments at the base black with green reflections; the femora are pitchy brown; the tibiAe pale yellowish with black spines; the tarsi of a deeper yellow; head dark brown, the trophi and a narrow line on the cheeks yellowish; antennae somewhat ferruginous.”
“External differences apparently so small, and which might elsewhere be deemed inadequate to the establishment of genera, become important in this remarkable family, from their being confirmed by the structure of the trophi, and the strong distinctions exhibited in their females in every instance that has yet presented itself to me, wherever I have had the certainty of specific identity in these heterogynous insects, from the direct observation of my friends in Australia.”
