76 TISSUE RESPIRATION IN INVERTEBRATES 



Coelenterata 

 Hydrozoa 



Physalia phy salts: Tentacles; Robbie, 1949 

 Anthozoa 

 Condylactis ,^iga7itea: Tentacles; Robbie, 1949 

 Gorgonia flabellum: Branches; Robbie, 1949 

 Plexaura flexuosa: Slices; Robbie, 1949 

 Mollusca 

 Pelecypoda 

 Crassostrea virginica: Mantle; Jodrey and Wilbur, 1955 

 Isognomon alata : Gill; Robbie, 1949 



Mercenaria mercenaria: Gill, mantle, adductor muscle; Hopkins, 1949 



Pinctada martensii: Gill; Kawai, 1957. Heart; Navez, Crawford, Benedict, and DuBois, 1941 

 Cephalopoda 

 Loligo pealeii: Gill; also retina, lens and "cornea" of eye; Robbie, 1949 

 Arthropoda 

 Crustacea 

 Panulinis argus: Leg nerve, leg muscle, midgut gland; Robbie, 1949 

 Effect: Inhibition of endogenous respiration and complete or partial reversal of this inhibition by 

 methylene blue; suggests the involvement of cytochrome oxidase; this effect noted in: 

 Mollusca 

 Pelecypoda 

 Crassostrea gigas: Mantle, gill; Kawai, 1958 

 Cristaria plicata: Gill; Higashi and Kawai, 1959 

 Hyriopsis schlegelii: Gill; Higashi and Kawai, 1959 

 Arthropoda 

 Crustacea 

 Homarus americanus'- Leg nerves and nerve cord; Chang, 1931 

 Effect: Inhibition of endogenous respiration by cyanide but the inhibition not reversible by methylene 

 blue; suggests that some terminal oxidase other than cytochrome oxidase may be involved in 

 electron transport; this effect noted in: 

 Mollusca 

 Pelecypoda 

 Crassostrea gigas: Gill; Okamura, 1959 

 Crassostrea virginica: Mantle; Jodrey and Wilbur, 1955 



ANTIMYCIN A 



Effect: Inhibition of respiration because the oxidation of succinate via the pathway involving the 

 Slater factor is blocked; this effect noted in: 

 Arthropoda 

 Insecta 

 Hyalophora cecropia: Wing epithelium of pupa and adult, Shappirio and Williams, 1957b 

 Periplaneta americana: Coxal muscles of legs of adult; Harvey and Beck, 19 53 



COMPARISON OF RESPIRATORY RATES OF VARIOUS TISSUES 



The following studies are concerned with the comparative endogenous respiratory rates of various 

 tissues of invertebrates; the results of no study are given here in their entirety.
