Notes on Stomatopod’s visual ability: 2

Abbreviation	Term	Description	Notes
MO[x]	mid-band ommatidia(中带复眼)	Basic units of a mid-band.	There are 6 rows of midband eyes, designated as MO[1-6]. Each ommatidium in MO[1-4] has 3 tiers of rhabdom. Each ommatidium in MO[5,6] has 2 tiers of rhabdom. A hemispherical ommatidium has 2 tiers of rhabdom.
R[x]	Rhabdomeres(感杆）	The elongated rod-like portion of the retinular cells, the subunit of the rhabdom, containing closely spaced and longitudinal rows of microvilli and pigment granules.	There are 8 types of rhabdomeres, designated as R[1-8]. R8 cells consist the most distal tier of rhabdom in all types (midband and hemispherical) of ommatidium.
DR[x]	Distally placed rhabdomeres（远端感杆）	Rhabdomeres that consist the distally placed rhabdom in MO[1-4], which is placed between the R[8] rhabdom and the PR rhabdom.	There are 7 types of DR, which are R[1-7]. They are specially designated as DR[1-7].
PR[x]	Proximal placed rhabdomeres（近端感杆）	Rhabdomeres that consist the proximally placed rhabdom in MO[1-4], which is placed at the proximal end, that is, close to the basement menbrane.	There are 7 types of PR, which are R[1-7]. They are specially designated as PR[1-7].
F[x]	Filter（滤光体）	Specialized, coloured intra-rhabdomal structures in MO[2,3], function as the filter of light in a specific wavelength band.	There are 2 layers of filters, designated as F[1], F[2]. F[1] is relatively distal and F[2] is relatively proximal.

Structure of hemispherical ommatidia

The General structure of MO[5,6] is similar to that of hemispherical ommatidia. However, the arrangement of microvillar in MO[5,6] are modified.
