The gossamer worm (Tomopteris, Neo-Latin from Greek meaning "a cut" + "wing" but taken to mean "fin") [3] is a genus of marine planktonic polychaetes. All described species are known to be holoplanktic , meaning that they spend their entire life cycles in the water column.
[4] [5] [6] Some species are bioluminescent, and produce a yellow light. [7] Their sperm differ from other annelids in having two tails. [8] Females produce gelatinous egg cases that floats in the water column. [9] [10] The animals use a type of propulsion called metachronal paddling, a sequential movement of multiple appendages.

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.
Forage fish: Forage fish occupy central positions in the ocean food webs. The organisms it eats are at a lower trophic level, and the organisms that eat it are at a higher trophic level. Forage fish occupy middle levels in the food web, serving as a dominant prey to higher level fish, seabirds and mammals. [28] Predator fish; Ground fish

The discovery rate of siphonophore species was slow in the 18th century, as only four additional species were found. [11] During the 19th century, 56 new species were observed due to research voyages conducted by European powers. [11] The majority of new species found during this time period were collected in coastal, surface waters. [11]
