“…Many crustacean larvae experience a shift in cardiac function through early development. For example, in the shrimp Metapenaeus ensis and isopod Ligia oceanica, a transition from myogenic to neurogenic cardiac control has been observed [68,69]. In the king crab L. santolla, the cardiac region becomes delineated from the megalopa to the juvenile [70], which may coincide with a shift in cardiac function [71].…”

Extant deep-sea invertebrate fauna represent both ancient and recent invasions from shallow-water habitats. Hydrostatic pressure may present a significant physiological challenge to organisms seeking to colonize deeper waters or migrate ontogenetically. Pressure may be a key factor contributing to bottlenecks in the radiation of taxa and potentially drive speciation. Here, we assess shifts in the tolerance of hydrostatic pressure through early ontogeny of the northern stone crab Lithodes maja, which occupies a depth range of 4-790 m in the North Atlantic. The zoea I, megalopa and crab I stages were exposed to hydrostatic pressures up to 30.0 MPa (equivalent of 3000 m depth), and the relative fold change of genes putatively coding for the N-methyl-D-aspartate receptorregulated protein 1 (narg gene), two heat-shock protein 70 kDa (HSP70) isoforms and mitochondrial Citrate Synthase (CS gene) were measured. This study finds a significant increase in the relative expression of the CS and hsp70a genes with increased hydrostatic pressure in the zoea I stage, and an increase in the relative expression of all genes with increased hydrostatic pressure in the megalopa and crab I stages. Transcriptional responses are corroborated by patterns in respiratory rates in response to hydrostatic pressure in all stages. These results suggest a decrease in the acute high-pressure tolerance limit as ontogeny advances, as reflected by a shift in the hydrostatic pressure at which significant differences are observed.

“…Yet, there is growing evidence that the development of the cardiovascular system in many groups is a complex and dynamic process, often involving phases that function in a very different way to one another and to the adult system (McMahon et al, 1997a;McMahon et al, 1997b;Reiber and Harper, 2001;Spicer, 2001;McMahon et al, 2002;Harper and Reiber, 2004). In insects, for example, there are distinct patterns of activity of the dorsal abdominal vesicle associated with larval, pupal and adult stages (Smits et al, 2000), whereas, for crustaceans, an ontogenetic shift has been suggested to occur from myogenic to neurogenic control of heart, although some groups appear to retain a myogenic control into adulthood (e.g.…”

SUMMARYThe molluscan cardiovascular system typically incorporates a transient extracardiac structure, the larval heart, early in development, but the functional importance of this structure is unclear. We documented the ontogeny and regulatory ability of the larval heart in relation to two other circulatory structures, the true heart and the velum, in the intertidal gastropod Littorina obtusata. There was a mismatch between the appearance of the larval heart and the velum. Velar lobes appeared early in development (day4), but the larval heart did not begin beating until day13. The beating of the larval heart reached a maximum on day17 and then decreased until the structure itself disappeared (day24). The true heart began to beat on day17. Its rate of beating increased as that of the larval heart decreased, possibly suggesting a gradual shift from a larval heart-driven to a true heart-driven circulation. The true heart was not sensitive to acutely declining P O2 shortly after it began to beat, but increased in activity in response to acutely declining P O2 by day21. Larval heart responses were similar to those of the true heart, with early insensitivity to declining P O2 (day13) followed by a response by day15. Increased velum-driven rotational activity under acutely declining P O2 was greatest in early developmental stages. Together, these findings point to cardiovascular function in L. obtusata larvae being the result of a complex interaction between velum, larval and true heart activities, with the functions of the three structures coinciding but their relative importance changing throughout larval development.

“…Heart rates in crustaceans typically become more regular and increase with early larval development before reaching a peak and then declining throughout the remaining duration of the animal's life, although there can be considerable variation in timing among species (McMahon et al, 2002;Reiber, 1997;Spicer, 2001;Spicer and Morritt, 1996). Peak heat rate of S. verreauxi was recorded with instar 9 phyllosoma which were approximately 20 mg in dry mass and 80 days post hatch.…”
