Phrynus longipes is a species of amblypygid (also referred to as whipspiders or tailless whipscorpions)[2] native to the Caribbean region.

[citation needed] Being nocturnal predators, they take shelter during the day and hunt primarily at night.

[6] Phrynus longipes occurs in a number of localities throughout the Caribbean, with the male holotype being from Haiti.

It is believed this is the case as most of the prey for this specific species also tends to gather around large tree stumps.

[7] Following these interactions, the spermatophore will be deposited into the female - ultimately resulting in fertilization and the development of an egg sac.

The females, due to their caring for the egg sac, are prohibited from mating freely with multiple males.

In the cases where polygyny does not occur, Phrynus longipes has been observed to take part in mate-multiply behavior.

[7] This means that one male will mate multiple times with the same female in order to ensure full paternal-ship of every clutch.

[7] Amblypygi including Phrynus species have been recorded as being preyed upon by reptiles and mammals, as well as other arachnids.
