J3 and J1A-crystallin gene expression in adult jellyfish rhopalia and tentacles. In situ hybridization on whole jellyfish (a–c, j–l) and cryosections (d–i). J3-crystallin (a, d, g, j) and J1A-crystallin (c, f, i, l) antisense riboprobes; J3-crystallin sense riboprobe (b, e, h, k). R, rhopalium; L, lens of large ocellus; SL, lens of small ocellus. (a, b, c) Arrows point to the surface of the lens of the large ocellus. (g, h, i) Arrowheads point to the tissue surrounding the lumen of the statocyst. (g) Arrows point to the staining in the outer aspect of the pigmented region of the ocellus. (j) Arrow points to the tip of a tentacle.
