Delphinidae

[thumb|[Puer in delphino est insigne urbis Tarenti. Nummus saeculi 6 a.C.n.]]
***Delphinidae*** sunt familia mammalium marinorum et fluviatilium superfamiliae Delphinoideorum.

Sunt circa quadraginta species animalium in septendecim generibus descriptae. Longitudo delphinorum variat ab 1.2 metris usque ad septem metra, et pondus ab quadraginta kilogrammatibus usque ad 4.5 tunnas. Delphini per totum orbem terrarum adsunt, praesertim in maribus brevibus. Carnivori sunt, pisces et loligines quaerentes.

Familia est maxima recentiorque inter Cetacea: delphini abhinc annorum circa 10 milliones evolverunt, in epocha Miocaeno.

Nomen *delphini* etiam comprehendit porcos marinos, sive thursiones.

## Taxinomia

Sex species delphinorum in quinque generibus familiae Delphinidarum sunt delphini balaenici.

## Evolutio 
Delphini cum balaenis et porcis marinis descendentis mammiferorum terrestrium, fortasse ordinis Artiodactylorum. Aquam iniverunt abhinc circa 50 miliones annorum. 

## Anatomia 
Delphinus corpus fusiforme habent, quod natatum adaptatum est. In capite pepo est, sensorium locationis resonantia seu echolocatio. In multis speciebus maxilla producta est, formans rostrum distinctum, et nonnulli species plurimum dentium habent. Cerebrum delphini magnum, et cortex bene structura est.

Color solitus delphini pullus est, cum infimo albiore et cappa atriore.
