FIGURE 11. Comparative morphologies of extant clitellate annelid cocoons. 1, Light micrograph of two earthworm (Oligochaeta: Lumbricus terrestris) cocoons with prominent polar extensions and walls constructed almost entirely of the solid alytine layer (from Clive A. Edwards, The Ohio State University, Columbus, USA, Public domain via Wikimedia Commons). 2, Light micrograph of a true leech (Hirudinea:?Macrobdella decora) cocoon with a wall dominated by a Dictyothylakos-like meshed hapsine layer (courtesy of Macroscopic Solutions, LLC. www.macroscopicsolutions.com). 3, Scanning electron micrograph of a crayfish worm (Branchiobdellida: Cambarincola macrocephelus or C. fallax) cocoon with a thin scabrate hapsine layer overlying solid alytine (courtesy of Dr Naglaa M SH Geasa, Tanta University, Egypt; after Geasa, 2014, figure 6G); co = cocoon body lacking an operculum; st = attachment stalk. Scale bars represent 1 mm in 1, 2; 50 µm in 3. ... : Published as part of McLoughlin, Stephen, Bomfleur, Benjamin, Mörs, Thomas & Reguero, Marcelo, 2016, Fossil clitellate annelid cocoons and their microbiological inclusions from the Eocene of Seymour Island, Antarctica, pp. 1-27 in Palaeontologia Electronica 11 (1) on page 18, DOI: 10.26879/607, http://zenodo.org/record/13331733 ...
