Biphragmosagittidae

Biphragmosagittidae is a family of chaetognaths, also known as arrow worms, a phylum of predatory marine worms that are a major component of plankton worldwide.

Taxonomy

The family Biphragmosagittidae belongs to the order Phragmophora, one of the two main orders of chaetognaths. The family includes two genera, Biphragmosagitta and Parabiphragmosagitta.

Morphology

Members of the Biphragmosagittidae family are characterized by their elongated, transparent bodies, which can reach up to 120 mm in length. They have a pair of lateral fins and a tail fin, which they use for swimming. The head is equipped with a set of sharp, grasping spines, which they use to capture prey.

Distribution and habitat

Biphragmosagittidae are found in oceans worldwide, from the surface to depths of over 1000 meters. They are particularly abundant in the Atlantic Ocean and the Mediterranean Sea. They inhabit both coastal and open ocean environments, and are often found in areas with strong currents or upwellings.

Ecology

Biphragmosagittidae are voracious predators, feeding on a wide variety of small planktonic organisms, including copepods, krill, and fish larvae. They are in turn preyed upon by a variety of larger marine animals, including fish and squid.

Reproduction

Like all chaetognaths, Biphragmosagittidae are hermaphrodites, possessing both male and female reproductive organs. They reproduce via external fertilization, releasing both eggs and sperm into the water column.

Research and significance

Biphragmosagittidae, like other chaetognaths, are an important part of marine food webs and play a significant role in the cycling of nutrients in the ocean. They are also used as indicators of water quality and oceanographic conditions.
