antennali

Antennali is a term encountered in biology and taxonomic literature to describe things relating to antennae, or to denote antennae structures in some languages, particularly Italian and other Latin-derived texts. In English-language usage, the adjective antennal is standard, while antennali appears mainly in non-English texts or as part of Latin-based scientific phrases.

In arthropods, antennae are paired sensory appendages on the head used for tactile sensing, chemical detection, and sometimes thermoreception or proprioception. The plural form antennali can be used to refer collectively to antennal structures across species or to antennae-like features described in multiple organisms.

In crustaceans, there are two sets of antennae: the antennules and the larger antennae. Antennal morphology—segment count, length, setae, and dentition—varies between taxa and is commonly described in taxonomic keys using antennal terminology or the adjective antennalis/antennali.

Functionally, antennal structures play a role in environmental perception, navigation, mating, and feeding. The study of antennal form and function is important in systematics, helping distinguish closely related species and clarifying ecological adaptations.

Notes: Antennali is not a standalone biological taxon; it is a descriptor. In Italian texts, it can serve as the plural form of “antennale,” and in Latin-based nomenclature, as an adjectival ending. See also Antenna (biology), Antennule, and Insect morphology.
