A survey of the Sipuncula of the Indian River Lagoon - Rice, M. E.; Piraino, J.; Reichardt, H. F. (Bulletin of Marine Science, 1995)
ABST; FROM 22 STAT. IN THE IND. RIV.LAG. RANGING FROM HAULOVER CANAL IN THE NORTH TO ST. LUCIE IN THE SOUTH 18 SP. OF SIPS ARE REPORTED. HABITATS INCLUDE OYSTER BEDS, SUBTIDEAL AND INTERTIDAL SANDS, SEA-GRASS BEDS AND SEA WALLS. THE GREATEST JNUMBER OF SP OCCURS NEAR INLETS: SABASTIAN, FR. PIERCE, & ST. LUCIE. THE MOST WIDELY DISTRIBUTED IN THE I.R.LAG. IS P’LION CRYPTUM AVER. 3 CM. IN LENGTH. USUALLY BURIED IN THE UPPER 5 CM. OF SANDY SEDIMENTS ASSOCIATED WITH SEAGRASS BEDS IT INHABITS DISCARDED GASTROPOD SHELLS IN SHALLOW WATGERS THRUOUT THE LAG.. DEVELOPMENT IS DIRECT, A CRAWLING VERMIFORM STAGE HATCHING FROM EGG COVERINGS WITHIN 2 DAYS. THE SECOND MOST WIDELY DISTRIBUTYED SIP. IS THEMISTE LAGENIFORMIS, ATTAINING A MAXIMUM EXTENDED LENGTH OF 4 CM.. OCCURING MOST COMMONLY NEAR THE INLETS OF FT. PIERCE & ST. LUCIE, IT IS ASSOCIATED EITHER WITH OYSTER BEDS, WHERE IT LIVES IN AND AMAONAG THE SHELLS, OR WITH THE ENCRUSTING FAUNA ON SEAWALLS, AMONG THE VERMATID SNAILS, SPONGES, AND TUNICATES. IN OYSTER BEDS NEAR FT. PIERCE IT OCCURS IN DENSITIES AS GREAT AS 2100/SQ.M.. THIS SP. IS PARTHENOGENIC; IT’S DEVELOPMENT INCLUDES AQ SHORT-LIVED, NON FEEDING PELAGIC LARVAL STAGE. OTHER SPECIES, FOUND MOSTLY IN SMALL NUMBERS NEAR THE INLETS, ARE CHARACTERIZED GENERALLY BY DEVELOPMENTAL PATTERNS WITH LONG-LIVED FEEDING PELAGIC LARVAE.

A functional organization of dermal coelomic canals in Sipunculus nudus (Sipuncula) with a discussion of repiratory designs in _____ sipunculans - Ruppert, E. E.; Rice, M. E. (Invertebrate Zoology, 1995)
ABSTRACT; S. N. IS A LARGE SIP. THAT BURROWS ACTIVELY IN COARSWE MARINE SANDS. THE BODY SURFACE IS FOLDED INTO APPROX. 30 LONGI. RIDGES THAT EXTEND ALONG THE LENGTH OF THE TRUNK AND INTROVERT. A DERMAL CANAL LIES BENEATH EACH OF THE RIDGES AND CIRCULATES COELOMIC FLUID AND HEMERYTHROCYTES TO WITHIN A FEW MICROMETERS OF THE BODY SURFACE. COELOMICFLUID ENTERS AND LEAVES THE DERMAL CANAL THRU PORES LEADING FROM THE TRUNK COELOM AND FLOWS UNIDIRECTIONALLY AT APPROXIMATELY 0.7 MM/SEC. FROM POST > ANTER. THE FLOW IS GENERATED BY CILIA ON PERITONEAL CELLS LINING THE CANALS. THE VOLUME OF THE CANALS IS APPROX. 8% OF THE TOTAL COELOMIC VOL. WE SUGGEST THAT SIP. SPECIES FALL INTO 3 FUNCTIONAL CATAGORIES BASED ON THE BODY REGION OR REGIONS USED FOR ENVIRONMENTAL GAS EXCHANGE. "TENTACLE BREATHERS" SUCH AS SPECIES OF THEMISTE, BORE INTO ROCKS OR MICRO-OXIC SEDIMENTS AND EXTEND THEIR NUMEROUS TENTS. INTO THE WATER. DISSOLVED GASES ARE TRANSPORTED BETWEEN THE TENT. & TRUNK COEL. CAVITIES VIA WELL DEVELOPED CONT. VESS.. "TENTACLE AND INTROVERT BREATHERS". SUCH AS SP. OF ASPIDO’IDAE & PHASCOLOSOMATIDAE, LODGE THE TRUNK BODY IN THE SUBSTRATUM AND EXTEND AN ELONGATED THIN WALLED INTROVERT AND TENTACLES INTO THE WATER. THEIR CONT.VESS. ARE USUALLY SIMPLE UNBRANCED TUBES. "INTEGUMENTARY BREATHERS", SUCH AS SIP.NUDUS AND OTHER SP. OF SIP’IDAE, HAVE INTEG. SPECIALIZATIONS FOR GAS EXCHANGE ACROSS THE ENTIRE BODY SURFACE, BUT USUALLY SMALL TENTACLES AND OFTEN WEAKLY DEVELOPED CONT.VESS.. METHODS / RESULTS / DISCUSSION (1, 2, 3 ABOVE)
