Like many sea creatures the Elysiachlorotica slug eats algae to survive. As a result of doing this, the sea snail takes the photosynthesizing chloroplasts from the algae and transfers them into its own body. This process is called “kleptoplasty”, in which the snail leaves the algae’s plastids intact allowing it to shortly benefit from energy generated through photosynthesis.
Sea Sheep? This Adorable Sea Slug Eats So Much Algae …
Seagrasses are often called nursery habitats because the leafy underwater canopy they create provides shelter for small invertebrates (like crabs and shrimp and other types of crustaceans), small fish and juveniles of larger fish species. Many species of algae and microalgae (such as diatoms), bacteria and invertebrates grow as “epiphytes” directly on living seagrass leaves, much like lichens and Spanish moss grow on trees. Other invertebrates grow nestled between the blades or in the sediments—such as sponges, clams, polychaete worms and sea anemones. The accumulation of smaller organisms amongst and on the seagrass blades, as well as the seagrass itself, attracts bigger animals. As a result, seagrasses can be home to many types of fish, sharks, turtles, marine mammals (dugongs and manatees), mollusks (octopus, squid, cuttlefish, snails, bivalves), sponges, crustaceans (shrimp, crabs, copepods, isopods and amphipods) polychaete worms, sea urchins and sea anemones—and the list goes on.
Knobbed Whelk (Busycon carica)! Christened the state seashell in 1987, the knobbed whelk is a whorled shell, eight inches long at maturity, displaying heavy spines, many knobs, and an orange or red mouth. Minerals in Georgia coastal waters cause ocher striations on the sand-colored, semi-gloss surface. This marine snail shell is found all along Georgia’s […]
