We normally assume either a Macropus or Abdopus (typically labled aculeatus) from Live Aquaria when they are labled Indonesian. However, occasionally we see a very small animal that does not live very long and have labled it abaculus (Roy's review of these suggest incorrect labeling). Dink had a very small mantle and relatively long arms. Her condition never allowed viewing of much body patterning but at her death, I noticed an unusual trait and would like a suggested id. The siphon is attached to the back of the head, fully outside the mantle. I have never taken notice of the back side of the mantle and never thought to photograph it after death but this immediately struck me as unusual.
