Callianira bialata

Callianira bialata is a species of ctenophora characterized by its gelatinous, lobed body with a pale pink coloration. The lower half of its body features two horn-like appendages, which in adult specimens can get as long as its body.^{[citation needed]}

The species exhibits two axes of symmetry, and possesses two retractable tentacles used to capture prey, each with numerous small branches called tentilla.^{[citation needed]}

If observed closely, eight vertical bands can be seen extending from the posterior part of the body. These bands contain paddle-like structures called cilia plates, which move synchronously. However, its mobility is limited, and the organism is primarily carried by ocean currents.

Unlike cnidarians, Callianira bialata does not possess stinging cells.^[2]

The vast majority of ctenophores, including Callianira bialata, feed on zooplankton (small organisms carried by currents) and ichthyoplankton (fish eggs and larvae). They capture their prey using sticky cells on their tentacles called colloblasts.^{[citation needed]}

These organisms are hermaphroditic, meaning they possess both female and male gonads. Reproduction occurs externally: individuals release eggs and sperm into the water, where fertilization takes place, resulting in the production of thousands of eggs. They exhibit a remarkably high reproductive capacity.^{[citation needed]}
