Summary[
edit] Description: English: Phytoplankton – such as this colony of Chaetoceros socialis – naturally give off fluorescent light as they dissipate excess solar energy that they cannot consume through photosynthesis.Source: Behrenfeld, M.J., Westberry, T.K., Boss, E.S., O'Malley, R.T., Siegel, D.A., Wiggert, J.D., Franz, B.A., McLain, C.R., Feldman, G.C., Doney, S.C. and Moore, J.K.

Illustration from Report on the Radiolaria collected by H.M.S. Challenger during the years 1873-1876. Part III. Original description follows: Plate 111. Aulosphærida. Diam. Fig. 1. Aulonia hexagonia, n. sp., × 30 The complete spherical shell. Fig. 2. Aularia ternaria, n. sp., × 300 A group of six triangular meshes, with seven nodal points of radial tubes. Behind the central capsule, with its double membrane (e, outer; i, inner) and radiate operculum (o); u, the two outer parapylæ; v, vacuoles in the protoplasm. The ellipsoidal nucleus (n) contains numerous nucleoli (l). Fig. 3. Aulastrum triceros, n. sp., × 50 The complete shell. Fig. 3a. Aulastrum triceros, n. sp., × 300 A single radial tube. Figs. 4a, 4b, 4c. Aulastrum dendroceros, n. sp., × 400 Three single radial spines (taken from three different specimens). Fig. 5a. Aulophacus lenticularis, n. sp., × 300 A single radial spine. Fig. 5b. Aulophacus amphidiscus, n. sp., × 300 A single radial spine. Fig. 6. Aulatractus fusiformis, n. sp., × 5 The complete shell, five times enlarged. Fig. 6a. Aulatractus fusiformis, n. sp., × 20 Apical part of the shell. Fig. 6b. Aulatractus fusiformis, n. sp., × 400 A single radial tube. Fig. 7. Aulatractus diploconus, n. sp., × 20 Apical part of the shell. Fig. 7a. Aulatractus diploconus, n. sp., × 400 A single radial tube. Fig. 8. Auloplegma perplexum, n. sp., × 50 Half the shell. Fig. 8a. Auloplegma perplexum, n. sp., × 400 A single radial tube. Fig. 9. Auloplegma spongiosum, n. sp., × 300 A single radial tube.
