Lycaenidae is the second-largest family of butterflies (behind Nymphalidae, brush-footed butterflies), with over 6,000 species worldwide, [1] whose members are also called gossamer-winged butterflies. They constitute about 30% of the known butterfly species.
Seagrasses then evolved from terrestrial plants which migrated back into the ocean. [ 14 ] [ 15 ] Between about 70 million and 100 million years ago, three independent seagrass lineages ( Hydrocharitaceae , Cymodoceaceae complex, and Zosteraceae ) evolved from a single lineage of the monocotyledonous flowering plants.
Limaria hians, the flame shell, is a species of small saltwater clam, a marine bivalve mollusc in the family Limidae. [1] This species is native to the northeastern Atlantic Ocean. Biology

The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
As well as being eaten by humans, the soft-shelled clam is relished by sea otters in the eastern Pacific Ocean, [citation needed] where the clam is an invasive species. In New England the soft-shell clam is preyed heavily upon by northern moon snails and invasive green crabs. They are also a favorite of gulls, which pull the clam from the sand ...
Like other clam species, A. islandia is a filter feeder.Feeding activity appears regulated by light levels, which can be used as a proxy for food availability. This means that at the northern extreme of the distribution, feeding is concentrated during eight months of the year, while during the rest of the year the clams only feed for a few days a month.
C. rosaceus lives on the surface of sandy seabeds and is nocturnal. It feeds on fragments of dead plant material and algae particularly among seagrass plants. In the process of feeding it grinds up sand particles with its Aristotle's lantern mouthparts, and it has been estimated that it reduces 5.5 kg (12.1 lb) of coarse particles of sediment into fine particles in the course of a year.
