1. What Does A Football Fish Look Like?
A football fish has a menacing appearance. It has a globular body about 6 inches long. It also has prickly skin, needle-sharp teeth, miniscule eyes, and a strange stalk on its head. The stalk, called the illicium, extends outward from the dorsal fin and ends in a bioluminescent bulb or esca.
To expand upon the appearance of a football fish, consider these characteristics:
- Size: Typically around 6 inches in length, although females can be significantly larger than males.
- Body Shape: Globular or football-shaped, hence the name.
- Skin: Prickly and dark in color, usually black or dark brown, to blend in with the deep-sea environment.
- Teeth: Needle-sharp and inward-pointing, designed to trap prey.
- Eyes: Small and often poorly developed due to the lack of light in their habitat.
- Illicium and Esca: The most distinctive feature is the bioluminescent lure (esca) at the end of a long stalk (illicium) extending from the head. This lure is used to attract prey in the dark depths.
1.1 Sexual Dimorphism
One of the most remarkable aspects of the football fish is the extreme sexual dimorphism between males and females. Females are significantly larger, sometimes up to ten times the size of their male counterparts. This size difference is due to the unique reproductive strategy of these fish.
1.2 Male Parasitism
In some anglerfish species, including the football fish, males have evolved into what are known as sexual parasites. The males use their highly developed olfactory organs to find females. Once a male finds a female, he fuses himself to her body. Over time, the male loses his eyes, internal organs, and everything else except his testes. He becomes a permanent appendage, drawing nutrition from the female and serving as a readily available source of sperm.
