Hedgpeth'S Sapsucker
elysia hedgpethi
Hedgpeth's Sapsucker (Elysia hedgpethi) is a fascinating marine gastropod belonging to the sacoglossan group, often referred to as sap-sucking sea slugs. Found along the Pacific coast of North America, this remarkable creature is famous for its solar-powered lifestyle. It feeds on green siphonous algae, particularly species of Codium, using a specialized radula to pierce the algal cell walls and suck out the cellular fluids. Instead of digesting everything, it selectively retains the living chloroplasts within its own digestive gland cells.
生息地: Typically found in intertidal rocky shores, estuaries, and coastal tide pools, closely associated with beds of green algae like Codium.
外見
This small, slender sea slug typically reaches lengths of 1 to 3 centimeters. Its body is primarily olive to bright emerald green, a color derived from the symbiotic chloroplasts inside its tissues. The dorsal surface features wing-like flaps called parapodia, which fold over its back and are often speckled with minute, iridescent blue, red, or white dots. Its head features two prominent, rolled rhinophoral tentacles used for sensing chemicals in the water, and its overall leaf-like shape provides excellent camouflage amidst marine algae.

おもしろい事実
Hatchlings are born completely translucent white; they only turn green after taking their very first meal of chlorophyll-rich green algae.
Their name Elysia honors the mythical paradise of Elysium, highlighting the elegant, leaf-like appearance of this genus.
They are widely known as 'solar-powered sea slugs' because of their ability to live off photosynthesis when algae is scarce.
特殊能力
能力
Solar Powered Symbiosis
Retains functioning chloroplasts from its algal prey, allowing it to undergo photosynthesis and survive without eating for weeks.
能力
Suction Feeding Radula
Features a specialized, blade-like radular tooth designed to puncture tough algal cells to extract cytoplasm without damaging the chloroplasts.
能力
Algal Mimicry Camouflage
Blends perfectly with its host algae due to its matching coloration, shape, and slow movement, avoiding predators.
食性と食事
Feeds exclusively on the cellular fluids of green siphonous algae, retaining the functional chloroplasts for energy.
年齢による違い: Planktonic veliger larvae feed on phytoplankton before metamorphosing and switching to a macroalgae diet.
