QUÉ SIGNIFICA SPICULE EN INGLÉS
Spicule
Las espículas son diminutas estructuras parecidas a picos de diverso origen y función que se encuentran en muchos organismos, como las espículas copuladoras de ciertos nematodos o los granos en la piel de algunas ranas. En las esponjas, las espículas realizan una función estructural. Las espículas son una parte muy importante de muchos organismos.
definición de spicule en el diccionario inglés
La definición de spicule en el diccionario también se llama: spiculum. una pequeña estructura puntiaguda o cristal, especialmente cualquiera de los elementos calcáreos o silíceos del esqueleto de esponjas, corales, etc. Otra definición de espícula es una eyección puntiaguda de gas caliente que se produce a más de 5000 kilómetros sobre la superficie del sol y que tiene un diámetro de cerca de 1000 kilómetros.
