SQUIRES Department of Geological Sciences, California State University, Northridge, California 91330, USA Abstract. The malleid bivalve Nayadina (Exputens) has Old World Tethyan affinities but is known only from Eocene deposits in North America. Nayadina (Exputens) is reported for the first time from Mexico. About 50 specimens of N. (E.) batequensis sp. nov. were found in warm-water nearshore deposits of the middle lower Eocene part of the Bateque Formation, just south of Laguna San Ignacio, on the Pacific coast of Baja California Sur. The new species shows a wide range of morphologic variability especially where the beaks and auricles are located and how much they are developed. A review of the other species of Exputens, namely Nayadina (E.) llajasensis (Clark, 1934) from California and N. (E.) ocalensis (MacNeil, 1934) from Florida, Georgia, and North Carolina, revealed that they also have a wide range of morphologic variability. Nayadina (E.) alexi (Clark, 1934) is shown, herein, to be a junior synonym of N. (E.) llajasensis. The presence of a byssal sinus is recognized for the first time in Exputens. An epifaunal nestling mode of life, with attachment by byssus to hard substrate, can now be assumed for Exputens. INTRODUCTION species. It became necessary to thoroughly examine them, The macropaleontology of Eocene marine deposits in Baja and after such a study, it was found that the Bateque California Sur, Mexico, is largely an untouched subject.

  • Structure and Function of the Digestive System in Molluscs
    Cell and Tissue Research (2019) 377:475–503 https://doi.org/10.1007/s00441-019-03085-9 REVIEW Structure and function of the digestive system in molluscs Alexandre Lobo-da-Cunha1,2 Received: 21 February 2019 /Accepted: 26 July 2019 /Published online: 2 September 2019 # Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract The phylum Mollusca is one of the largest and more diversified among metazoan phyla, comprising many thousand species living in ocean, freshwater and terrestrial ecosystems. Mollusc-feeding biology is highly diverse, including omnivorous grazers, herbivores, carnivorous scavengers and predators, and even some parasitic species. Consequently, their digestive system presents many adaptive variations. The digestive tract starting in the mouth consists of the buccal cavity, oesophagus, stomach and intestine ending in the anus. Several types of glands are associated, namely, oral and salivary glands, oesophageal glands, digestive gland and, in some cases, anal glands. The digestive gland is the largest and more important for digestion and nutrient absorption. The digestive system of each of the eight extant molluscan classes is reviewed, highlighting the most recent data available on histological, ultrastructural and functional aspects of tissues and cells involved in nutrient absorption, intracellular and extracellular digestion, with emphasis on glandular tissues. Keywords Digestive tract . Digestive gland . Salivary glands . Mollusca . Ultrastructure Introduction and visceral mass. The visceral mass is dorsally covered by the mantle tissues that frequently extend outwards to create a The phylum Mollusca is considered the second largest among flap around the body forming a space in between known as metazoans, surpassed only by the arthropods in a number of pallial or mantle cavity.

  • Lab 5: Phylum Mollusca
    Biology 18 Spring, 2008 Lab 5: Phylum Mollusca Objectives: Understand the taxonomic relationships and major features of mollusks Learn the external and internal anatomy of the clam and squid Understand the major advantages and limitations of the exoskeletons of mollusks in relation to the hydrostatic skeletons of worms and the endoskeletons of vertebrates, which you will examine later in the semester Textbook Reading: pp. 700-702, 1016, 1020 & 1021 (Figure 47.22), 943-944, 978-979, 1046 Introduction The phylum Mollusca consists of over 100,000 marine, freshwater, and terrestrial species. Most are familiar to you as food sources: oysters, clams, scallops, and yes, snails, squid and octopods. Some also serve as intermediate hosts for parasitic trematodes, and others (e.g., snails) can be major agricultural pests. Mollusks have many features in common with annelids and arthropods, such as bilateral symmetry, triploblasty, ventral nerve cords, and a coelom. Unlike annelids, mollusks (with one major exception) do not possess a closed circulatory system, but rather have an open circulatory system consisting of a heart and a few vessels that pump blood into coelomic cavities and sinuses (collectively termed the hemocoel). Other distinguishing features of mollusks are: z A large, muscular foot variously modified for locomotion, digging, attachment, and prey capture. z A mantle, a highly modified epidermis that covers and protects the soft body. In most species, the mantle also secretes a shell of calcium carbonate. z A visceral mass housing the internal organs. z A mantle cavity, the space between the mantle and viscera. Gills, when present, are suspended within this cavity.

Coelomates are so named because they have a true bivalve coelom, a hollow, fluid-filled cavity that is completely surrounded incurrent siphon by mesoderm. Coelomates differ from pseudocoelomates, such as excurrent siphon roundworms, which have a Body cavity lined By mesoderm on the cephalopod outside and endoderm on the inside.

  • Lower Carboniferous Pelecypods of the Northwest Wing of the Moscow Basin
    VOPROSY PALEONTOLOGII, Vol. III, 1960 LOWER CARBONIFEROUS PELECYPODS OF THE NORTHWEST WING OF THE MOSCOW BASIN M. Ė. YANISHEVSKIY [IANISHEVSKII]* [p. 67] Family Amussiidae Ridewood Genus PROTOENTOLIUM nov. gen. Diagnosis. The shell is oval, slightly convex, equivalved; auricles are small, triangular. The anterior auricle of the left valve is larger than the posterior and is slightly raised upward, which is why the hinge margin forms not a straight, but rather an angular- concave line. Beaks are small, sharp-angled, and occupy a middle position. The main part of the shell is of triangular outline, and is delimited by two depressions widely diverging from expanded anterior and posterior margins of the shell. There is no hollow for the byssus on the anterior auricle. Both valves, by and large, are smooth, with slight concavity. The external surface of the left valve is smooth, with numerous, very fine concentric growth lines. The external surface of the right valve, however, also has, in addition, coarser concentric traces of growth, especially closer to the outer margin. Internal characters. On the steinkerns, impressions of two oblique ribs, proceeding from the beak to the anterior and posterior margins and containing bases of the auricles, are visible. “Cardinal ribs,” proceeding parallel to this margin, are visible on the hinge margin of the valves. There apparently is a smooth, narrow groove in the interspace between them. The anterior auricle of the left valve is strongly pushed upward and consists of two parts: the posterior - curved and triangular, tapering upward, with arcuate posterior margin, and the anterior -narrow, curved, lying more deeply from the hinge area and far from the posterior sharp curving projection.
