The Diet Of Goliath Frog
A study revealed that Goliath frogs have diverse diets, actively hunting both on land and in water.
Younger frogs show a preference for annelids, arachnids, myriapods, insects, crustaceans, gastropods, and reptiles.
In contrast, fully grown individuals primarily favor arachnids, myriapods, insects, crustaceans, and gastropods, with a notable preference for myriapods.
Young Goliath frogs’ varied diet hints at diverse adult preferences, possibly including fish, small mammals, and amphibians.
Reproduction of The Goliath Frog
Water plays a vital role in Goliath frog reproduction, like most amphibians.
In contrast to other frog species, they don’t produce mating calls due to the lack of a vocal sac.
Instead, egg masses usually contain hundreds to thousands of 3.5 mm (0.14 in) diameter eggs attached to aquatic vegetation.
Goliath frogs create nests by clearing pools, expanding existing ones, or digging new ones, including moving stones.
Moreover, adult Goliath frogs guard nests at night, with males likely constructing them and females protecting the eggs.
Lastly, larval development takes 85 to 95 days.
Life Cycle Of The Goliath Frog
Lamotte, Perret, and Zahl’s studies enabled the creation of a chronological table for larval development.
In the initial 24 hours, the egg mass turns yellow, and eggs become dark gray-brown, often attached to plants.
During the first month, organs remain undifferentiated, with pigmentation in the ocular region.
Their length is 8 to 10 mm (0.31–0.39 in), with slight pigmentation in the body and tail, and mostly white abdomen.
In the second month, tadpoles actively feed on leaves, showing denser pigmentation.
Spiraculum and anal tube become visible, and they develop teeth. Sizes range from 19 to 21 mm (0.75–0.83 in), increasing to 24 mm (0.94 in).
By the third month, posterior legs form, tadpoles reach about 40 mm, and posterior legs grow with distinct joints and fingers.
Tadpoles are 45 mm long, anterior legs appear, mouths become arched slot lines, tail regression begins, and tadpoles breathe by poking their heads out.
In the fourth month, all specimens complete metamorphosis, with reabsorbed or nearly absent tails.
They attain adult shape and color, measuring 35 mm (1.4 in).
The entire larval development takes about 85–95 days.
