Ectotermos y Endotermos: ¿Qué son y cuál es la diferencia?

En el mundo animal, existen dos tipos principales de regulación de la temperatura corporal: ectotermos y endotermos. Estos términos describen la forma en que los animales mantienen y controlan su temperatura interna. En esta entrada, exploraremos en detalle qué son los ectotermos y endotermos, y cuál es la diferencia entre ellos.

1. ¿Qué son los Ectotermos?

Los ectotermos son animales que obtienen la mayor parte de su calor del entorno externo. Esto significa que su temperatura corporal varía según las condiciones ambientales. Los ectotermos no tienen la capacidad de regular su temperatura interna de manera eficiente y dependen del calor externo para calentarse o enfriarse.

Los ectotermos son comunes en reptiles, anfibios, peces y la mayoría de los invertebrados. Por ejemplo, las serpientes, los lagartos y las tortugas son ectotermos. Estos animales pueden ser activos y tener una temperatura corporal alta cuando el entorno es cálido, pero se vuelven menos activos o incluso inactivos cuando las temperaturas descienden.

2. ¿Qué son los Endotermos?

Los endotermos son animales capaces de generar y mantener su propia temperatura corporal interna, independientemente de las condiciones externas. También se les conoce como animales de «sangre caliente». Los endotermos pueden regular su temperatura corporal mediante procesos metabólicos internos, como la producción de calor a través del metabolismo de los alimentos y la regulación del flujo sanguíneo.

Los endotermos incluyen mamíferos y aves principalmente. Estos animales tienen una amplia gama de adaptaciones para mantener una temperatura corporal constante, como pelaje o plumaje aislante, glándulas sudoríparas y sistemas de circulación eficientes.

3. Diferencias entre Ectotermos y Endotermos

Ahora que hemos definido los términos, vamos a explorar las diferencias clave entre ectotermos y endotermos:

3.1. Origen del calor

La principal diferencia radica en cómo obtienen el calor. Los ectotermos dependen del calor del entorno externo, mientras que los endotermos generan y mantienen su propio calor interno.

3.2. Regulación de la temperatura corporal

Los ectotermos tienen una temperatura corporal que fluctúa según las condiciones ambientales. Por otro lado, los endotermos pueden mantener una temperatura corporal constante, independientemente de las condiciones externas.

3.3. Actividad y Metabolismo

Los ectotermos suelen ser menos activos en condiciones frías, ya que su metabolismo se ralentiza. Por el contrario, los endotermos son más activos y tienen un metabolismo más rápido, lo que les permite mantener una temperatura corporal constante y realizar actividades incluso en entornos fríos.

3.4. Adaptaciones físicas

Los endotermos suelen tener adaptaciones físicas específicas para mantener su temperatura corporal, como pelaje, plumaje o capas de grasa aislante. Los ectotermos no tienen estas adaptaciones físicas especializadas.


En resumen, los ectotermos son animales cuya temperatura corporal depende del entorno externo, mientras que los endotermos tienen la capacidad de generar y mantener su propia temperatura corporal interna. Los endotermos, como mamíferos y aves, pueden regular su temperatura corporal, mientras que los ectotermos, como reptiles y anfibios, no pueden hacerlo de manera eficiente. Estas diferencias en la termorregulación tienen un impacto significativo en el comportamiento, el metabolismo y la adaptación de los animales a diferentes entornos.

Es importante destacar que estas categorías no son exclusivas y hay excepciones. Algunos animales pueden tener características de ambos grupos, como algunos peces que tienen la capacidad de regular su temperatura corporal de manera limitada. La termorregulación es un campo fascinante de estudio en la biología, y comprender las diferencias entre ectotermos y endotermos nos permite apreciar la diversidad y complejidad del reino animal.
