Toutes les espèces sont dangereuses si on pose le pied dessus
Les plus grosses peuvent infliger une piqûre mortelle.
Elles s'enfouissent sous le sable en quelques coups de nageoires et seuls leurs yeux restent visibles. Les plus petites peuvent se cacher ainsi très près du bord des plages et piquer les baigneurs qui les écrasent sans les avoir vues.
