“…The total lipid level was much higher in the ovary than in the testis of S. mollis during gametogenesis. A similar difference was noted in Pisaster giganteus (Greenfield et al 1958). Even in equally sized gonads of S. mollis, more energy was deposited in the ovaries than in the testes, which supports the conclusion that the energetic demands on the female are greater than on the male in many asteroids (Lawrence and Lane 1982).…”

Abstract. Seasonal changes in biochemical composition of tissues are compared in a shallow inshore and deeper offshore population of the seastar Sclerasterias mollis (Hutton, 1872) on the Otago shelf, New Zealand, from 1985 to 1986. The biochemical composition of the body wall, gonads and pyloric caeca of the two populations did not differ greatly, even though reproductive output and nutrient storage of reserves were consistently higher in the offshore population. The biochemical composition of the ovaries and testes differed. High levels of carbohydrate and lipid were maintained in the ovaries from the commencement of vitellogenesis until spawning occurred. The testes had higher ash levels during spermatogenesis. During the annual reproductive cycle, an inverse relationship in the carbohydrate levels between the ovary and the pyloric caeca suggests nutrient transfer from the pyloric caeca to the gonads during gametogenesis. Annual changes in biochemical composition indicate that the body wall is also used for nutrient storage.

“…340 mg coelomocytes (fresh wt), corresponding to 33 mg dry wt or 4.2 mg lipid. The last value is in good agreement with data from other studies that indicate that the same amount of coelomic fluid (including coelomocytes) contains 1.5-6.5 mg lipid depending on the asteroid species studied (Greenfield et al, 1958;Giese, 1966;Oudejans and Rutten, 1982). If the supply of fatty acids is not limited as in the described in vitro experiments, this amount of coelomocytes can accumulate approx.…”

Abstract--1. The turnover of fatty acid and amino acid in the coelomic fluid of the sea star Ar'terias rubet, ~s was quantified by intra-coelomic injection of radiolabelled oleic acid and L-leucine which had half time .s of 2 and 10 min, respectively.2. The molar composition of the amino acids of the cell-free coelomic fluid was determin.ed. The totai q concentration of amino acids was 4.33 + 1.93/~g/ml; the total concentration of fatty acids was 0.34 #g/ml.3. In a period of 4weeks, 74mg of fatty acid and 201 mg of amino acid is transferred through the coelomic fluid of a standardized 100 g animal.4. In vitro experiments allow an estimation of the apparently minor role ofcoelomocytes in lipid transport. 5. Transport of fatty acid and amino acid through the perivisceral coelomic fluid can by far not meet the demands of the ovaries during vitellogenesis. Therefore, other systems (haemal and perihaemal) must play an important role.

“…However, at the present time several marine forms have been suc cessfully kept in apparently healthy condition for prolonged periods of time in the laboratory or on floats which could be illuminated or darkened: oysters (73,74), barnacles (76), an annelid worm (77,124), some starfishes (78), and a sea urchin (79). Oysters, particularly, should make excellent material for studies of the influence of daylength upon breeding, since so much is known about their cytology (75,80,81,82) and general biology erated in nature during the spring diatom outburst and that in the laboratory they are liberated even when the diatoms are supplied unseasonally early (in winter).…”

Interest in the study of the physiology of reproduction is of relatively recent date and has developed largely in the last forty years. Interest in the physiology of reproduction of the invertebrates is of even more recent date. In fact, the most complete and up-to-date compendium of compara tive animal physiology (1) omits the subject entirely. Yet it is known that in the invertebrate world exists a diversity of modes of reproduction from primitive to highly evolved, asexual3 as well as sexual (2,3,125,126). Here is to be seen, so to speak, the evolution of the animal reproductive process, a procession of nature's fascinating experiments. Investigators have to some extent realized the opportunities for such studies, and many articles on the physiology of reproduction in invertebrates are widely scattered in the literature in a variety of journals. Neglect of discussion of the physiology of the reproductive processes of the invertebrates, then, has not been for lack of material but rather for lack of a synthesis of the existing literature.It would be impossible in a single brief review to cover completely the physiology of invertebrate reproduction, desirable as it might be. Rather, this review considers only the annual reproductive cycles of marine inver tebrates, with special emphasis on papers which include interesting view points, experimental approaches, or provocative material.A few general references which give considerable information on annual reproductive cycles of marine invertebrates are: the Handbook of Biological Data (4), in which is found a table containing breeding seasons and related data for invertebrates from various places; a book on methods for obtaining and handling marine eggs and embryos (5) of East Coast invertebrates (particularly for animals from the Woods Hole area); a paper (6) on New Zealand invertebrates; two books (7, 8) and several papers (9, 10) on West 1 The information in this article covers the literature as far back as seemed feasible to go and includes citations up to August, 1958. Wherever possible, reference is given to key review articles which give references to older literature. If important or inter esting work was omitted, it was unintentional.2 I am indebted to the staff of the Stanford Biological Libraries: Mr. F. Falconer, Chief Science Librarian, Miss Joanne Dandois, and Mr. Michael Sadoski without whose help it would have been impossible to make the extensive bibliographic search.3 Asexual reproduction occurs in many groups of animals, among them the Pro tozoa, Porifera, Coelenterata, Platyhelminthes, Rotifera, Tunicata, and certain Annelida (Polychaeta). These are dealt with in general works (2, 3) on the inverte brates. Considerable research on polychaetes is referred to by Durchon (123). Dode caceria, one of the most interesting of the polychaetes, has a remarkable capacity for asexual reproduction, and Martin's paper (125) and references cited by him should be consulted for information. 547 Annu.
