Loggerhead turtles can use their powerful jaws to
crush prey like conches, crabs and other animals with
hard shells. But they also eat softer foods such as
jellyfish, seaweed and a brown alga called sargassum.
Loggerheads are no landlubbers
Loggerhead turtles (Caretta caretta) live in oceans all over the world,
except in the most frigid waters. Having paddle-like flippers for
swimming, and streamlined carapaces, loggerheads are renowned
for their long-distance oceanic migrations (up to 4,800 km or 3,000
miles),1 and pin-point accurate navigation. (Adult females often
exhibit natal beach nesting, i.e. laying their eggs on the very same
beach where they themselves hatched.)
Despite their evident aquatic prowess, evolutionists say these sea
turtles are “limited by their land-dwelling ancestry”, as they must
breathe air and nest on dry land. 2
But a creationist perspective makes much more sense. Their need to
breathe air is no impediment to them at all, being able to dive for up
to 20 minutes, and even rest for hours without breathing. (In any case,
loggerheads’ food is mostly found in the relatively shallow coastal
waters, where their average dive is only three to four minutes.) Their
‘attachment’ to land during their lifetimes is minimal: no more than
t wo months as eggs buried in sand, a few hours at most as hatchlings
journeying from nest to sea, and a few hours again for adult females
when making landfall to lay eggs. So loggerheads are best viewed
as sea creatures, created on Day 5 of Creation Week.
But some might ask, how could sea turtles have survived the global
Flood of Noah’s day, with no dry land available for nesting, if they
were not taken aboard the Ark? The answer lies in the fact that
females only nest every two to five years. So, once the Flood waters
went down, the surviving sea turtles could begin reproducing again.
Female loggerheads lay up to five clutches of eggs in one nesting
season, with up to 150 eggs per clutch—that’s a lot of turtles! Thus
loggerhead populations could rapidly recover from Flood losses and
from any interruptive effect of the Flood on reproductive cycles.
Loggerheads attain mature size between 10 and 30 years of age, and
reproductive life span after reaching maturity is estimated at about
32 years. So, it's no problem for loggerheads to survive the Flood.
